Syzygiumcuminiis a folklore plant traditionally indicated to treat various inflammatory disorders. In this study anti rheumatic activity of oral administration of petroleum ether extract of Syzygiumcumini stem bark at the doses of 50,500,750,1000, mg/kg on complete Freund’s complete adjuvant induced arthritis has been studies in rats. The treatment is assessed by measuring the paw volume, body weight, arthritic index, and rheumatoid factor. The investigated result showed that the extract inhibited the CFA induced arthritis in dose dependent manner and this effect was more significant (P<0.05) with 1000mg/kg dose. The standard drugs Indomethacin (10mg/kg), dexamethasone (0.1mg/kg) also produce significant anti rheumatic effect in rats and is compared with test drug. The result suggest that the petroleum ether extract of Syzgiumcuministem bark produced significant anti-rheumatic effect.

Arthritis is a form of joint disorder that involves inflammation of one or more joints [1-2]. Rheumatoid arthritis (RA) is a systemic autoimmune multisystem disease characterized by joint inflammation, morning stiffness, and destruction of articular tissues and restricted joint movement [3-5]. Arthritis can cause severe disability and ultimately affects a person’s ability to carry out normal tasks, restricts the quality of life and causes premature death . Any part of the body can become inflamed or painful from arthritis. Arthritis is the most common inflammatory disorders affecting approximately 0.5-1.0% of the global adult population, with female being affected three times more than males [7-9]. RA still remains a formidable disease, producing severe crippling deformities and functional disabilities and cartilage destruction and commonly leads to significant disability, caused by no. of pro-inflammatory molecules released by macrophages including reactive oxygen species and eicosanoids such as, cytokines, leukotrienes, and prostaglandin. The regulation of these mediators secreted by macrophages and other immune cells and modulation of arachidonic acid metabolism by inhibiting enzymes like Cox and LOX are the potential target for chronic inflammatory conditions.
The prevalence of rheumatoid arthritis varies between 0.3% and 1% worldwide and is more in developed countries. It mainly affects women that man (3:1). Rheumatoid arthritis is a chronic systemic inflammatory illness with a prevalence of approximately 0.75% in India. .
Syzygiumcumini(L) is an important medicinal plant used for treatment of diabetes , ulcers, some pharmacological activity like anti-allergic, gastro protective, anti-oxidant, anti-fertility, anti-viral.
Materialsl and Methods
The stem bark of Syzygiummcumini was collected from natural habit and around Hyderabad. The plant was aunthentifed by Prof. P Jayaraman, PARC Chennai.
Reg no of Certificate: PARC/2010/652.
Preparation of Extract
The collected stem bark of Syzygiummcumini was cleaned, dried in the shade and cut in to coarse powder and extracted with petroleum ether as solvent. The extraction of petroleum ethers extract is done by using soxhlet apparatus b hot percolation method. The extraction is carried with 2 litres of solvent for a period of 72 hours. At the end of extraction the yields was in brown oil and it was concentrated in vaccum at 400C using a rotary evaporator and the residues was stored in a freezer at -800C for further tests.
Male wistar rats of approximately the same age, weighing about 150-200g was selected for the study. There were housed in the polypropylene cages and were giving feed with standard diet and water ad libitum.The study has got approved from IAEC(Institutional Animal Ethical Committee) of CPCSEA.
Acute Toxicity Studies
Acute toxicity study was performed for petroleum ether extract according to acute toxic classic method as per OECD guidelines.
Induction of Arthritis 
Arthritis was induced in all the animals of each group by an intra-dermal injection of complete Freund’s adjuvant suspension of 0.1ml in the planter surface of left hind paw which contains 1.0 mg dry heat killed Mycobacterium tuberculosis per millilitre sterile paraffin oil. Acute inflammation in the form of paw edema was produced after injecting CFA suspension.

Freund’s complete adjuvant induced arthritis model are extensively used to study the pathogenesis of rheumatoid arthritis for testing therapeutics. One of the reasonfor the wide utilization of this model is due to strong correlation between efficacy of therapeutic agents in the model and in rheumatoid arthritis in human and it is characterized by very rapid erosive disease. In adjuvant arthritis bacterial peptidoglycan and muramyl dipeptide are responsible for arthritis induction. It occurs through cell mediated autoimmunity by structural mimicry between myco bacterial and cartilage proteoglycans in rats.
The present study was designed to evaluate the anti-arthritic activity of Petroleum ether extract of Syzygiumcumini which is very was reported to contain betulinic acid, beta sitosterol, friedelin, epi-friedelanol, gallic acid.
In the present study involves the release of number of mediators like cytokines, granulocyte monocyte colony stimulating factor, interferons. These mediators are responsible for the pain, destruction of bone and cartilage that can lead severe disability. Paw swelling is one of the major factors in assessing the degree of inflammation and therapeutic efficacy of the drugs.
The pain, inflammation and swelling of joints in arthritis can be greatly reduced by different compounds of Syzygiumcumini. In contrast to the traditional NSAIDs which are reported to produce gastric ulceration and bleeding. But this plant has been reported to have gastro protective effect.
From the previous studies bark, seed leaves extract of this plant are having anti-inflammatory, antidiabetic and antibacterial activity.
Change in body weight has also been used to assess the course of disease and the response to the therapy of anti-inflammatory drugs. Adjuvant arthritis is characterized by reduced weight loss and the body weight loss is associated with increased production of pro inflammatory cytokines such as TNF-alpha and IL-1. Test drug showed significance increase the body weight as that of the vehicle control group.
In the present study the test extract in the doses of 750, and 1000mg/kg had anti-inflammatory effect as it decreased the paw edema significantly. Results of this study are in agreement to the available literatures.
The present studty was designed to evaluate the Anti rheumatic activity of petroleum ether extract of Syzygiumcumini stem bark.
The petroleum ether extract of Syzygiumcumin bark had a better effect on controlling CFA induced rheumatoid arthritis.
