Abstract
The Fabaceae (Leguminosae) plant family contains several species of the Mucuna Adans. genus possessing therapeutic potential and growing widely in tropical and sub-tropical regions. In this research, we investigated the anti-inflammatory and antioxidant properties of the extract from the Mucuna sanjappae Aitawade & S.R.Yadav seeds. Initially, we conducted an in vitro anti-inflammatory activity test using the bovine serum albumin anti-denaturation assay and found promising dose-dependent activity. Subsequently, we performed an in vivo anti-inflammatory and antioxidant study on a rat paw edema model induced by carrageenan. Three different doses of M. sanjappae seed water extract (50, 100 and 200mg/kg B/W) were used for the study (Oral administration). Edema measurement was carried out at 0, 2, 4 and 6 hr intervals. Dose dependent inhibition in edema in the M. sanjappae seed extract treatment group was observed with maximum activity for 200mg/kg B/W dose at 4 hr (53.49%). Standard drug showed maximum edema inhibition (54.94%) at 6hr. Our results also showed that, M. sanjappae seed extract inhibited pro-inflammatory cytokine TNF-α and increases anti-inflammatory cytokine IL-10 with increased level of blood serum antioxidants. Phytochemical analysis for secondary metabolites including polyphenol, flavonoids, phytic acid, proanthocyanidin, tannin and saponin was also quantified which might be the responsible component for biological activities under study.

Introduction
Inflammation can be defined as essential response exhibited by host after tissue injury or infection. However, its longstanding persistence may result in chronic diseases like cancer, cardiovascular diseases, neurological disorders, diabetes, pulmonary diseases, and arthritis1-7. Inflammation is characterized by pro-inflammatory enzymes, chemokines, cytokines, and certain signal proteins generated in response to infection or injury. Management of inflammatory diseases today represents an important medical problem since currently used non-steroidal anti-inflammatory drugs (NSAIDs) has several other adverse effects commonly known as gastroenteropathy1,7. Hence, identification of novel and effective therapies for safer management of inflammatory diseases remains an urgent priority. Natural plant wealth is continually being investigated for novel bioactive molecules with therapeutic properties. In contrast to modern synthetic drugs, natural bioactive are cost effective and provides significant protection from diseases without secondary adverse complications. Therefore, researchers are investigating plant-based drugs which can provide promising anti-inflammatory activity with lower secondary complications8. Numerous reports endorse the use of various plants for treating inflammation1,9.
Genus Mucuna belongs to family fabaceae, popularly known as cowitch, kapikachu and atmagupta. Mucuna species are recognized for their itching properties due to hairs present on the pods. Since ancient time, Indian ayurveda system of medicine uses seeds of Mucuna for the management of different types of diseases and disorders. Remarkable research has been carried out on Mucuna pruriens particularly for its anti-Parkinson’s, anti-infertility, anti-venom, anti-inflammatory and anti-bacterial activity7,10-16. Mucuna seed powder is very common ingredient in various ayurvedic formulations marked in India and across the world. However, exploitation of M. pruriens at large scale may affect ecosystem adversely and due to limited availability, final product cost may also increase. To avoid this, there is increasing interest in investigating hidden potential of other underutilized Mucuna spp. as a promising alternative therapeutic agent. Previously, our research group have successfully reported Mucuna species including M. macrocarpa, M. bracteata, M. imbricata and M. sanjappae etc. for their nutritional and medicinal benefits15-24. In 2019, we have reported L-DOPA (L-3,4-dihydroxyphenylalanine), an FDA approved anti-Parkinson’s drug in seeds of different Mucuna species found in Indian contingent and proved that number of Mucuna species possesses higher level of L-DOPA as compared to the commonly used M. pruriens25.
M. sanjappae is endemic plant species found in Western Ghats region of Maharashtra, India which belongs to genus Mucuna26. In previous studies we have demonstrated that M. sanjappae seeds possess promising level of nutritional components with gross energy 383 kcal and around 5.43 g of protein. Moreover, it contains about 7.3 % L-DOPA and other important primary and secondary metabolites, minerals, important phenolics etc. Furthermore, anti-Parkinson’s activity of M. sanjappae seed extract in Parkinson’s disease (PD) mice model intoxicated by MPTP is reported18,19. M. sanjappae seed extract could successfully ameliorate PD symptoms developed by MPTP toxicity. However, till date, there is no data available on the effect of M. sanjappae on inflammatory diseases and oxidative stress using in vitro or in vivo model. Carrageenan induced rat paw edema model is popular method of anti-inflammatory studies of natural as well as synthetic drugs1. Hence, present efforts have been made to examine anti-inflammatory and antioxidant properties of M. sanjappae seed on carrageenan induced rat paw edema model.
Material and Methods
Chemicals and reagents
Analytical grade solvents and chemicals were used the study. Carrageenan and enzyme-linked immunosorbent assay (ELISA) cytokine kits for TNF-α and IL-10 measurement were obtained from Sigma-Aldrich, USA. Diclofenac (Standard anti-inflammatory drug) was obtained from Recon, Bangalore, India respectively.
Plant material and preparation of drugs for administration
The pods of M. sanjappae were collected from its original location (Pune district, Western Ghats, Maharashtra, India). The herbarium was carefully prepared and stored at the herbarium center of the Botany department, Shivaji University, Kolhapur under the guidance of taxonomist Prof S. R. Yadav.
After removing the healthy seeds from the pods, fine powder was prepared. Extract of seed was produced by adding and macerating 1g M. sanjappae seed powder in 100 ml D/W in the mortar and pestle. Further, sonication for 15min and centrifugation at 10000 rpm for 10 min was carried out. Supernatant was carefully separated and stored for further use. Effective yield was calculated by evaporating water. Importantly, seed extract and standard drug diclofenac were prepared freshly at the time of dosing.
In vitro anti-inflammatory activity
Bovine serum albumin (BSA) anti-denaturation assay
This test was performed using a method defined earlier with slight modifications27. Various concentrations of seed extract and standard drug diclofenac were reacted with 1ml of 1% BSA solution prepared in 50mM Tris buffer (pH 6.5). Incubation was carried out at 37°C for 20 min and further heating at 64°C in water bath till mixture get turbid (around 5 to 10 min). Finally, tubes were cooled, and absorbance of generated turbidity was measured at 660 nm. D/W was used as a control. Following formula was used to calculate denaturation inhibition percentage:
% denaturation inhibition = A (control) – A (sample) / A (control) X 100
Where, A (control): Absorbance of the control; A (sample): Absorbance of samples.
Hypotonicity-induced HRBC membrane stabilization method
Capacity of M. sanjappae seed to protect hypotonicity encouraged human red blood cell membrane protection have been determined28. Various concentrations of M. sanjappae seed extract were made into 1 mL using distilled water in a tube. Initially, 0.5ml of 10% HRBC suspension and 0.5 mL of 0.25% hyposaline were added to each tube. Then, mixture was incubated at static condition for 30 mins at 37°C and centrifuged at 3000 rpm for 20 mins at 4°C. The amount of hemoglobin in the supernatant was performed at a wavelength of 560 nm. Working solution of standard drug aspirin was prepared in 0.2 M phosphate buffer (1 mL) at various concentration ranging from 100 µg to 500 µg. To induce complete hemolysis (100%) without any sample or drug, a control was prepared using distilled water as a replacement for hyposaline. To calculate the percentage of HRBC hemolysis and evaluate the degree of membrane stabilization or protection, below given formula was employed:
% of hemolysis = Absorbance of test/ Absorbance of control x 100
% protection = 100 – (% of hemolysis)
In vivo anti-inflammatory activity
Rats were divided into seven groups (6 rats per polypropylene cage) housed under controlled conditions (Relative humidity 44–56 %, temperature of 25±2 °C, and 12 h light/ dark cycles). Standard diet and water ad libitum was provided to the experimental animals. The experiment was started after proper acclimatization of animals in the laboratory environment after a week. Details of randomization, grouping and drug dosing are given in table 1. Seven days prior dosing was carried out by M. sanjappae seedextractin group IV, V, VI and VII. On the 8th day rats were kept fasted but water was provided ad libitum. Extract was administered 2hr before inducing the inflammation by carrageenan (0.9%) through sub plantar way and further investigation was accomplished.

Rat paw edema measurement
The inflammation in terms of swelling of carrageenan induced foot of animal was measured using plethysmometer (UGO Basile, Italy) as a water displacement in ml. The measurement was done at 0, 2, 4 and 6 hr. The decrease in paw volume was compared to the vehicle control. The percentage of inhibition in seed water extract and diclofenac treated group was compared with carrageenan induced group.
Inhibition Percentage (%) = [Carrageenan treated group-test drug group / Carrageenan treated group] X 100
Inflammatory biomarkers and Oxygen radical absorbance capacity (ORAC) assay
TNF-α and IL-10 concentration in serum of control and drugs treated respective groups was determined using ELISA kit. The experiment was performed as per instructions of manufacturer. TNF-α and IL-10 level was expressed as picogram per milligram (pg/mg).
Antioxidant level of serum samples in treated and control animal group was carried out by ORAC method29. Shortly, 25 μl of serum sample added in fresh 150 μl of 10nM fluorescein solution and allowed to stand at 37 0C for 30 min. After incubation, 25 ml of AAPH substrate (500mM) mixed and the fluorescence was calculated for 150 min at 485 and 520nm (Excitation and emission wavelengths respectively) using microplate reader. Standard trolox was used as a and results were expressed as micromoles of Trolox equivalents (TE) per liter of sample.
Phytochemical analysis
The total polyphenol level of M. sanjappae seeds was determined spectrophotometrically30 and represented as mg of gallic acid equivalent per gram (mg GAE g–1) of dry mass. Theflavonoids content was analyzed31 and results represented as milligram of quercetin equivalents per gram (mg QUE g-1) of dry weight. Proanthocyanidin examined and reported as catechin equivalents per gram (mg CAE g-1) of dry weight32. The phytic acid was determined and absorbance was measured at 500 nm33. Tannin and saponin level also studied according to methods reported earlier34,35.
Statistical Analysis
GraphPad Prism 5 is used for data analysis. All the results were represented Mean ± SEM. P-values of less than 0.05 were considered as significant.
Results and Discussion
Nature has gifted us with medicinally important, inexhaustible sources of secondary metabolites, including alkaloids, terpenoids, phenolics, saponins, and other classes of organic compounds. These phytometabolites have tremendous health benefits for the overall growth and the management of diseases. Over time, experimental procedures and tools for the isolation, characterization, validation, and development of drugs for disease have been well established36. The present attempt was aimed to find out the anti-inflammatory and antioxidant properties of M. sanjappae seeds for future natural drug development.
In vitro anti-inflammatory activity
Preliminary screening of anti-inflammatory potential was performed using table assay as given below:
Bovine serum albumin (BSA) anti-denaturation potential:
Denaturation of proteins causes several inflammatory responses in the body. Many synthetic drug molecules show promising anti-inflammatory activity37 but are known to cause secondary complications after long-term use38. Hence, the use of plant-mediated drugs may prove more advantageous than their synthetic counterparts. M. sanjappae seed extract has shown inhibition of heat-induced albumin denaturation activity at different concentrations, as shown in Fig. 1. M. sanjappae extracts showed strong inhibition of albumin denaturation (87.73±3.81%) at 500μg/ml concentration. The standard drug diclofenac showed 94.82± 1.79% inhibition at 500 μg concentration. The results suggested good anti-inflammatory activity of M. sanjappae seed extract.

HRBC Membrane stability potential
Stabilisation of lysosomal membrane is an essential process in the regulation of inflammation process. It occurs by preventing the release of lysosomal components of active neutrophils including bactericidal enzymes and proteases. Red blood cell membrane bears resemblance to lysosomal membrane28, therefore understanding the stability of RBC membrane by our drug of interest gives idea about its potential to protect lysosomal membrane to prevent release of inflammatory response markers. Haemoglobin released in the supernatant in the control tube (without std drug or plant extract) due to bursting of red blood cells, while the yellow supernatant in the plant extract tube indicates the stabilisation of HRBCs. Our results demonstrated that M. sanjappae seed extract could protect the HRBC membrane with maximum protection at 500ug M. sanjappae seed extract (60.47±2.1 %) as depicted in Fig. 2. As concentration of M. sanjappae seed extract was increased, HRBC membrane stability was also increased suggesting concentration dependent stabilization activity by M. sanjappae seed. Standard drug aspirin showed superior HRBC membrane protection capacity as compared to M. sanjappae seed extract. The maximum protection by aspirin at 500ug concentration was 99.56±1.01 and it also represented dose dependent increase in activity.

In vivo anti-inflammatory activity
Carrageenan is a sulfonated polysaccharide widely used in food industries. It is extracted from red seaweed algae. It does not have any nutritional potential but is preferentially used as thickening, gelling and emulsifying agent39. Several studies have successfully reported use of carrageenan as an inflammatory agent to induce acute paw edema1. It is a simple and effective mean of assessing anti-inflammatory properties of drug.
Paw edema measurement
Determination of paw edema level after carrageenan toxicity and its furth treatment using oral dose of M. sanjappae seed extract was evaluated. Carrageenan generates acute paw edema which can be seen as redness and swelling at the site of injection. In the present study, paw edema was induced by using carrageenan and measured at 0hr, 2hr, 4hr and 6hr post injection. Carrageenan toxicity successfully developed inflammation in the rat paw which was evident from redness and swelling at the site of induction with highest paw thickness at 4hr (9.44±0.25). Vehicle control animal group does not show edema. Animal group treated with different doses of M. sanjappae seed extract exhibited significant reduction in the paw edema with maximum result at 200mg/kg body weight (Table 2). It showed 53.49% of edema inhibition after 4 hr treatment. Standard drug showed maximum edema inhibition (54.94%) at 6hr.The anti-inflammatory potential of M. sanjappae seed extract was observed very close to the standard drug Diclofenac control group. Dose dependent increase in the anti-inflammatory activity of M. sanjappae seed extract in respect to edema reduction was clear from the study. Sham control group was given the highest dose of M. sanjappae seed extract (200mg/kg body weight) and does not show any inflammatory symptoms during the experiments. Our finding supports anti-inflammatory potential of M. sanjappae seed and its traditional use in the management of inflammation related disorders.

Effect of M. sanjappae treatment on pro-inflammatory cytokine TNF-α
TNF-α is a mediator of inflammatory responses playing a key role in the development of innate immune system via activating macrophages, T cells and secretion of other inflammatory cytokines. In the carrageenan induced acute inflammatory model, complement system stimulation along with inflammatory mediators’ synthesis are major events 40. Serum TNF-α level was determined after 6hr post carrageenan treatment (Fig 3a). There was considerable increase in TNF-α (89±8.13 pg) in serum due to inflammatory response after carrageenan injection confirming its pro-inflammatory properties (Group II). However, treatment of M. sanjappae seed extract at various doses significantly decreased TNF-α level. Among tested doses, 100 and 200mg dose significantly reduced (p<0.01) TNF-α level (59.5±4.48 pg and 57±1.96 pg respectively) in animal (Fig 3a) and we found superior results as compared to standard drug diclofenac (61.3±6.61 pg). Vehicle control and Sham control represented normal TNF- α level. According to the results, it can be concluded that, M. sanjappae has potential of reducing the inflammation caused by external toxic compounds and possesses potential to use for managing inflammatory diseases.

Effect of M. sanjappae treatment on anti-inflammatory cytokine IL-10
IL-10 is an important anti-inflammatory cytokine which attenuates the activity of pro-inflammatory markers including TNF- α41. In the present study, in contrast to TNF- α, IL-10 level was increased in Diclofenac and M. sanjappae seed extract treated animal groups (Fig. 3b). Reduction in IL-10 in carrageenan induced group (II), suggests, carrageenan exerts its anti-inflammatory response through suppression of anti-inflammatory cytokines. Positive effect of M. sanjappae seed extract was validated from considerable augmented IL-10 level (p<0.001) with maximum activity at 100 and 200mg M. sanjappae seed extract dose. Vehicle control (I) and SHAM control (VII) exhibited normal level of IL-10 which was higher than carrageenan induced group II. Overall, our study signifies M. sanjappae exerts its anti-inflammatory action by suppressing pro-inflammatory cytokines and expressing anti-inflammatory cytokines in the serum of carrageenan toxicated rat.

Oxygen radical absorbance capability (ORAC) assay
Serum antioxidant levels of different animal groups is studied by oxygen radical absorbance capacity method1. Serum antioxidant activity was significantly (p<0.001) elevated in M. sanjappae seed extract treated animal group. The higher activity was found for 100 and 200mg/kg B/W dose. There was also significant increase in serum antioxidant capacity in sham control animal suggesting M. sanjappae seed possesses secondary metabolites which are enhancing antioxidant properties in the animal. Carrageenan control showed lower level of serum antioxidant activity (468±31.6µM Trolox equiv/L) suggesting oxidative stress is get generated due to toxicity of carrageenan. Different doses of M. sanjappae seed extract showed 560±22.4, 905±53.8 and 1105±42.4 µM Trolox equiv/L respectively showing concentration dependent increase in oxygen radical absorbance potential (Fig 4).

Human disorders show pathogenesis through cellular inflammation and oxidative stress mediated cell degeneration. An inbuilt antioxidant system comprising antioxidant molecules and enzymes performs a crucial role in removing free radicals7,42. But increased oxidative stress because of environmental toxins, genetic changes, or unknown causes results in cell components/organelle to degenerate or alter leading to apoptosis of cell. In such cases, supplementary antioxidants through food or drugs become essential way of disease management. Present study demonstrated M. sanjappae seeds contains vital phyto-metabolites which have capacity to induce anti-inflammatory and antioxidant properties required in the disease treatment.
Phytochemical analysis
Phenolics and flavonoids are considered as major secondary metabolites with prominent role as antioxidant and anti-inflammatory agents20,21,22,24. These secondary metabolites are with diverse biological activities combating diseases through multiple pathways. Their role in managing diseases including neurodegenerative diseases is via unstable superoxide radicals scavenging and cellular inflammation decreasing pathway43. M. sanjappae showed 80.78±2.56 mg GAE g-1 of phenolics and 419.5±7.18 mg QAE g-1 of flavonoids. Earlier we have analyzed gallic acid, tannic acid, p-hydroxybenzoic acid and p-coumaric acid as major phenolic compounds present in M. sanjappae seeds using HPLC20. M. sanjappae seed possesses higher levels of flavonoids than polyphenols which may be attributed to the specificity, and accuracy of reaction and respective standard used for the reaction. Proanthocyanidin level was 2.14 ± 0.13 mg CAE g-1. Proanthocyanidin is flavan-3-ol group having compound with strong antioxidant, anti-inflammatory, antihypertensive, antimicrobial and antiallergic activity44-46. M. sanjappae seed contains a higher concentration of phytic acid 197.23±0.11 mg g-1. Phytic acid is metal chelating and anti-inflammatory in nature 47,48. Phytic acid decreased inflammation by reducing the level of NF-κB and p-ERK in MPTP intoxicated PD mice model48. It is also natural iron chelating agent which prevents iron induced dopaminergic neuron degeneration in Parkinson’s disease49. M. sanjappae beans showed 0.52±0.11 mg g-1 and 18.71 ± 0.13 mg g-1 of tannin and saponin content respectively. Both of these compounds possess anti-inflammatory and antioxidant activity50, 51.
Investigation of traditional ayurveda knowledge with respect to disease management has lain to find novel drug molecules and related molecular pathways responsible for it. In modern medicine, single synthetic drug is preferred for targeted and quick action. But on the other side, those synthetic molecules usually have several side effects to the patients. In this connection, plant-based drug therapy which comprises several effective drug molecules proves to be most effective and moreover exerts minimum side effects. Based on the present results, M. sanjappae may prove as a promising lead for treating inflammatory diseases.
Conclusion
Natural drugs isolated from plants show promising anti-inflammatory properties with little to no side effects. Local indigenous peoples have been using Mucuna species as a staple food and medicinal purposes, mainly for Parkinson’s disease, male infertility, and snake bite treatment. However, there has been no elaborative investigation of the anti-inflammatory properties of M. sanjappae using in vivo or in vitro model. The present study revealed the anti-inflammatory potential of M. sanjappae seed extract by inhibiting pro-inflammatory cytokines and upregulating anti-inflammatory cytokines. The carrageenan-induced edema was reduced after treatment with M. sanjappae seeds’ water extract. Furthermore, the antioxidant level was elevated after the treatment by M. sanjappae extract. Phytochemical analysis confirmed presence of active secondary metabolites such as phenolics, flavonoids, phytic acid, saponins etc. Thus, the study strongly supported therapeutic potential of M. sanjappae and suggests further molecular-level investigations for its future exploration as a pharmacological agent in the management of inflammation and oxidative stress-related diseases.
