Nowadays, there is a growing interest in using natural antioxidants rather than synthetic ones. In this study, the antioxidant activity of Ginkgo biloba's active compounds was investigated by addition of its extracts in vegetable oils. The rate of oxidation was determined by Oxidograph apparatus at the temperature of 110 deg C. The collected leaves of Ginkgo biloba were extracted with ethanol and their antioxidant activity was compared with the commercial extract of Ginkgo biloba and also with the synthetic antioxidant BHT. It was found out, that both of ginkgo extracts demonstrated an antioxidant activity, but it was lower than the antioxidant activity of BHT.
