Abstract: The present study reports the phenol and flavonoid contents of Cistus ladaniferus and Mentha suaveolens from Northern Morocco and the evaluation of their in vitro antioxidant and antimicrobial activities against gram positive, gram negative bacteria, and yeast. The results showed that the highest phenol and flavonoid content found in the aqueous extract of Cistus ladaniferus. However, the methanol extract of Mentha suaveolens contains the high phenol and flavonoid contents.  A significant anti-DPPH activity was obtained with aqueous extract of Mentha suaveolens and Cistus ladaniferus with IC₅₀ values of 8.78 ± 0.02μg/mL and 2.93± 0.02μg/mL, respectively. An important anticandidal effect of MSEO as observed against Candida albicans. The most sensitive bacteria to all extracts were B. subtilis, P. mirabils and S. aureus.  Our findings indicate that the natural compounds of Cistus ladaniferus and Mentha suaveolens with an antimicrobial activity could be a good target for the antioxidants and antimicrobial industry. However, further investigations regarding the isolation of phenolic bioactive compounds and the evaluation of their antioxidant and antimicrobial properties are required.
