高良姜提取物的降血糖活性

Hypoglycemic Activity of Extract of Alpinia officinarum

利用α-葡萄糖苷酶抑制活性筛选对海南产高良姜的不同提取部位及其主要化学成分进行降血糖活性测试。结果表明,高良姜的根茎、花、果实和茎叶的乙醇提取物及其主要成分高良姜素、山奈素、异鼠李素和槲皮素对α-葡萄糖苷酶的抑制活性显著高于阳性对照药阿卡波糖。

Hypoglycemic activity of main constituents and extracts of different parts of the plant lesser galangal （Alpinia officinarum Hance） were determined using inhibitory assay of α-glucosidase.The results indicated that ethanol extracts of the rhizome,flowers,fruits and leaves of A.officinarum and its main ingredients galangin,kaempferol,isorhamnetin and quercetin all produced obviously higher inhibitory activities against α-glucosidase than the positive control acarbose.Hypoglycemic activities of flowers,fruits and leaves of A.officinarum were first reported,which provides basis for the study and development of the waste material in the harvest of A.officinarum.
