Toxicity of \u3cem\u3eGynandropsis pentaphylla\u3c/em\u3e DC Extracts Against Microbials and Its Phytochemical Profile

Fresh leaves, roots, stems, seeds and seed pods of Gynandropsis pentaphylla DC were used in extractions with benzene and ether. Fresh extracts were tested against 6 bacteria and 4 fungi using the well diffusion method. Extracts of roots, stems, leaves, seeds and seed pods were screened phytochemically for the presence of secondary metabolites such as tannin, alkaloid, flavones, sugar, phenolic group, essential oil, amino acids and saponin. All the phytochemicals were observed in all the plant part extracts using both ether and benzene. Among the bacterial cultures, Agrobacterium tumefaciens (NCIM 2145) was highly susceptible (28.0±0.3 mm) to both ether and benzene extracts of the leaves of G. pentaphylla. Also A. tumefaciens showed the highest average zone of inhibition for all extracts. Among the fungi, Penicillium notatum (NCIM 747) was highly susceptible (25.0±0.0 mm) to the benzene extracts of G. pentaphylla leaves. The extracts of leaves showed highest activity among all the plant parts. Highest activity index was observed for all extracts against the fungus P. notatum
