Abstract: Scavenging effect of ginkgolide extract from Gingko biloba leaves against O^-,OH^-, hydrogen peroxide was investigated. Extract from Escherichia coli was added into producing systems of free radicals and hydrogen peroxide in order to show scavengingeffect of ginkgolide extract from Gingko biloba in cells. It is indicated that ginkgolide extract from Gingko biloba leaves did not show strongs cavenging effect against O^-,OH^-, hydrogen peroxide. It is suggested that mutual function between flavonoid extract and ginkgolide extract from Gingko biloba leaves was very complexin scavenging process on free radicals and hydrogen peroxide. It is also proved that scavenging effect of ginkgolide extract from Gingko biloba leaves against O^-,OH^-, hydrogen peroxide were not changed by extract from Escherichia coli.

Key words: Gingko biloba leaves, Ginkgolide extract, Free radicals, Hydrogen peroxide
