ABSTRACT
Stephania japonica (Thunb.) Miers and Cocculus hirsutus (L.) Diels (Menispermaceae) are the most commonly used medicinal plants to cure various human ailments. Antimicrobial and qualitative phytochemical studies have been carried out in them using chloroform, ethanol and aqueous extracts. Studies showed that leaf ethanolic extracts of Stephania japonica has high potent against E.coli, and Pseudomonas aeruginosa and while chloroform extract of the same plant has potent against Vibrio cholera and Streptococcus pneumoniae. Ethanolic extracts of Cocculus hirsutus(leaf) showed high potency against E.coli, and Pseudomonas aeruginosa also. Phytochemical studies reveal the presence of tannins, alkaloids and, proteins and other biocompounds.
Keywords: Antibacterial, phytochemical, biocompounds. Stephania japonica, Cocculus hirsutus.
