以23个银杏雄性优株为材料，比较了银杏叶甲醇提取液的抗氧化能力（DPP

Using 23 excellent male Ginkgo biloba plants as materials, the antioxidant capacity (DPPH•, OH•, O2-• clearance rate and total reducing power) and functional components (total flavonoids, terpene lactones) of the methanol extract of Ginkgo biloba were compared. , Polysaccharides, proanthocyanidins) content differences among individual plants, and based on cluster analysis and correlation analysis, the antioxidant properties of Ginkgo biloba extract and the material basis of its antioxidant effect were discussed.

Based on 23 Ginkgo male excellent strains, the antioxidant ability (DPPH, OH, O2-removal rate and total reduction force) and functional content (total flavonoids, steroids, polysaccharides, progesterone) were compared, and the antioxidant properties and antioxidant properties of Ginkgo biloba extract were discussed based on polysaccharide analysis and correlation analysis.

The antioxidant capacity (DPPH ·, oh ·, O2 - ·) and the contents of functional components (total flavonoids, terpenoids, polysaccharides and procyanidins) of methanol extract from Ginkgo biloba leaves were compared among individual plants. The antioxidant properties and antioxidant activities of the extracts were discussed based on cluster analysis and correlation analysis Material basis for use
