中文摘要
目的探讨紫色悬钩子(RSI)水提物在体内、体外对α-葡萄糖苷酶(AG)的抑制活性。方法利用酶-抑制剂体外筛选模型,阿卡波糖为对照品,对不同浓度的RSI进行体外酶抑制活性研究。体内进行糖耐量试验,正常小鼠分别ig RSI 40、10 g·kg-1,阿卡波糖0.375 g·kg-1,生理盐水0.3 mL,连续5 d,分别负荷葡萄糖2.0 g·kg-1、淀粉2.0 g·kg-1,在15、30、60、120 min时测定小鼠的血糖值。结果 RSI 0.0195~2.50 mg·mL-1时,体外酶抑制率为5.20%~88.81%;阿卡波糖1.5625~25.00 mg·mL-1时,抑制率为9.28%~64.87%;淀粉糖耐量的提高作用比葡萄糖糖耐量的明显(P
