Study on Anti-bacterium Activities of Extract of Ginkgo biloba Leaves(EGbs)and Ginkgolic Acids(GAs)

Abstract

Abstract: Anti-microbial activities of EGbs contatining different concentration Ginkgolic acids and Ginkgolic acids were assayedand the different pH and heat treatment effects on anti-microbial activity of Ginkgolic acids were assayed also.It was concludethat Ginkgolic acids in the EGb was the main anti-microbial ingredient, and showed specially strong inhibiting effect on G+bacterium, and anti-microbial activity was enhanced with the increasing of concentration and the acting time of Ginkgolic acids.Ginkgolic acids showed also certain heat stability.

Key words: EGb, Ginkgolic acids, anti-microbial
