目的对金樱子乙醇提取物进行抗氧化和抑制α-葡萄糖苷酶活性的研究。方法用β-胡萝卜素-亚油酸漂白法,DPPH和NO自由基清除实验来衡量金樱子乙醇提取物的抗氧化活性;用α-葡萄糖苷酶抑制实验来测定金樱子乙醇提取物抑制α-葡萄糖苷酶的活性。结果金樱子乙醇提取物随着浓度增加抗氧化活性和α-葡萄糖苷酶抑制活性逐渐增大,但弱于阳性对照品。结论金樱子乙醇提取物具有较好的抗氧化和一定的抑制α-葡萄糖苷酶的活性,并且有助于将来进一步开发利用金樱子。

Objective To study antioxidative activity and α-glucosidase inhibitory activity of ethanol extract from Rosa laevigata Michx.（R. laevigata）. Methods The antioxidative activity of ethanol extract from R. laevigata were determinated byβ-carotene-linoleic acid bleaching, DPPH and NO scavenging assay. And the α-glucosidase inhibitory activity of ethanol extract from R. laevigata was measured by α-glucosidase inhibitory assay. Results The ethanol extract from R. laevigata showed strong antioxidant activity and possessed α-glucosidase inhibiti...
