摘要: 以银杏(Ginkgo biloba L.)外种皮为原料,乙醇回流提取粗多酚,选择D-101型大孔树脂纯化,分别用30%、50%、70%、90%乙醇洗脱,考察不同洗脱物的多酚含量及抗氧化抑菌活性,研究大孔吸附树脂纯化对银杏外种皮多酚抗氧化及抑菌活性的影响。结果表明,90%乙醇洗脱物多酚含量最高,抗氧化活性最强。胡萝卜汁产生菌的抑菌结果表明,90%乙醇洗脱物的抑菌活性明显高于粗提物。D-101型大孔树脂适用于银杏外种皮多酚的初步纯化。

Abstract: The total polyphenols were extracted by ethanol reflux method, and the D-101 macroporous resin was used to purify the total polyphenols to study the effect of antioxidation and antibacterial activities on polyphenols from ginkgo(Ginkgo biloba L.) fruit sarcotesta separation by macroporous adsorption resin. The macroporous adsorption resin was eluted by 30%,50%,70%,90% ethanol and to inspect the polyphenol content and the antioxidant and antibacterial activity of different elution. Results showed that 90% ethanol elution had the highest polyphenol content and the highest antioxidant activity. The results showed that the antibacterial activity of 90% ethanol elution on the bacteria from carrot juice was significantly higher than that of crude extract. D-101 macroporous resin is suitable for the preliminary purification of polyphenols from ginkgo fruit sarcotesta.

Key words: ginkgo(Ginkgo biloba L.) fruit sarcotesta, polyphenol, antioxidant, antibacterial activity, macroporous resin
