| 目的：探讨昆仑雪菊提取物对α- 葡萄糖苷酶的抑制活性。方法：将昆仑雪菊干燥花序粉碎, 分别用水提法和乙醇法制备5
种提取物。采用α- 葡萄糖苷酶体外活性抑制模型, 测定昆仑雪菊的5 种提取物对α- 葡萄糖苷酶的抑制活性。结果：这5 种提取
物对α- 葡萄糖苷酶活性有较强的抑制作用，抑制活性均高于阿卡波糖。其中提取物Ⅰ的抑制活性最强，IC50 =28.2 mg/L。结论：
昆仑雪菊提取物具有较高的α- 葡萄糖苷酶抑制活性，提示昆仑雪菊在抗糖尿病产品开发方面具有很好的应用前景。 |

| Objective: To investigate the inhibited effect of Coreopsis tinctoria flowers extracts from the Kunlun Mountain on
alpha-glycosidase. Methods: The dry inflorescence of Coreopsis tinctoria flowers wre crushed, and then five extracts with water and alcohol
extraction were prepared, respectively. The inhibitory activity on alpha-glycosidase of the five extracts of Coreopsis tinctoria flowers
were identified by vitro activity inhibition models of alpha-glycosidase. Results: The five extracts have higher inhibition activity on
alpha-glycosidase than acarbose. Among them, the extract Ⅰ had the most inhibited effect with IC50=28.2mg/L. Conclusion: The extracts
have inhibited effect on alpha-glycosidase, which indicated Coreopsis tinctoria flowers had good application prospects in antidiabetic
product development. |
