The methanol extract of kiwifruit leaf suppressed the postprandial blood glucose level after an oral administration of soluble starch or sucrose in mice. The mechanism of action is proposed to be due to the alpha-amylase-inhibiting activity in the 90% aqueous methanol fraction and alpha-glucosidase-inhibiting activity in the n-buthanol fraction, based on the results of in vitro experiments.
猕猴桃叶的甲醇提取物在小鼠口服可溶性淀粉或蔗糖后可抑制餐后血糖水平。根据体外实验结果,其作用机制被认为是由于90%甲醇水溶液部分具有α-淀粉酶抑制活性,正丁醇部分具有α-葡萄糖苷酶抑制活性。
