Preliminary Study on the Anti-oxidative Damage Substances of Ginkgo Flavone Components

Ginkgo flavonoids are extracts of Ginkgo biloba leaves with precise antioxidant activity. In this study, a model of human umbilical vein endothelial cell chemical injury was established. Based on the cell viability, nitric oxide (NO) content and lactate dehydrogenase (LDH) content, the preliminary antioxidant bases of different ginkgo flavonoids were discussed. The study found that 45% ethanol component can effectively improve cell survival rate, has damaged cell repair function, and there is synergy and antagonism between different components, which provides reference and guidance for subsequent product development.
