Comparative phytochemical composition and antimicrobial potential of leaf and twig extracts of Ginkgo biloba L. from India
Antimicrobial potential of leaf and twig extracts of Himalayan gymnosperm Ginkgo biloba L. has been determined by agar well diffusion and agar dilution methods respectively. Strains of five Gram positive bacteria were used as test organisms. Plant extract were prepared in different organic solvents (methanol, hexane and DCM). All plant extracts exhibited antimicrobial activity against all these tested bacterial strains. Methanolic extract of leaf and twig, and hexane leaf extract of G. biloba showed maximum activity against E. coli with Minimum Inhibitory Concentration (MIC) 2.01, 2.53 and 2.97 mg/mL, respectively.
