目的 研究金银花水提液在体外对α-淀粉酶、α-葡萄糖苷酶活性的影响.方法 用超声波处理和直接水煮制备金银花水提液,采用碘-淀粉比色法和PNPG法分别测定金银花水提液对α-淀粉酶、α-葡萄糖苷酶活性的影响.结果 两种金银花水提液对α-淀粉酶的活性具有抑制作用,且抑制效果随提取液浓度的增加而增大;对α-葡萄糖苷酶的活性也有抑制,超声波处理的金银花水提液的作用能力较强.结论 金银花提取液在体外对α-淀粉酶和α-葡萄糖苷酶的活性均有一定的抑制作用,因而金银花可能具有降血糖功能.
目的 研究金銀花水提液在體外對α-澱粉酶、α-葡萄糖苷酶活性的影響.方法 用超聲波處理和直接水煮製備金銀花水提液,採用碘-澱粉比色法和PNPG法分彆測定金銀花水提液對α-澱粉酶、α-葡萄糖苷酶活性的影響.結果 兩種金銀花水提液對α-澱粉酶的活性具有抑製作用,且抑製效果隨提取液濃度的增加而增大;對α-葡萄糖苷酶的活性也有抑製,超聲波處理的金銀花水提液的作用能力較彊.結論 金銀花提取液在體外對α-澱粉酶和α-葡萄糖苷酶的活性均有一定的抑製作用,因而金銀花可能具有降血糖功能.

Objective To study the effects of ultrasonic treatment and water boiled honeysuckle extraction on activities of amylase and α-glucosidase in vitro. Methods Honeysuckle extracts were prepared by ultrasonic treatment and direct water boiling respectively, then the effects of honeysuckle extracts on activities of amylase and α-glucosidase were determined separately by iodine-starch colorimetric technique and PNPG method. Results The results showed that both extracts inhititory effects on activities of amylase and α-glucosidase in a concentration dependent manner. While on α-glucosidase, ultrasonic processed honeysuckle extract showed stronger inhibitory effect. Conclusion Honeysuckle extracts have some inhibitory effects in vitro on the activities of amylase and α-glucosidase, indicating the honeysuckle may have function of reducing blood glucose.
