摘要
本研究收集全国各地的37种豆豉样品,测试其水提物对α-葡萄糖苷酶体外抑制活性。结果表明:37种来源不同的豆豉样品水提物均对小鼠肠道内的α-葡萄糖苷酶呈现一定程度的抑制活性,其中5#(L.Y)、16#(W.N.H)以及21#(M.W)豆豉水提物对α-葡萄糖苷酶呈现较高的抑制活性(P<0.05);此外,通过对高活性豆豉的蔗糖和葡萄糖含量检测,结果表明,尽管豆豉中含有微量的葡萄糖,但抑制干扰作用甚微。本研究结果预示着豆豉中存在可以强烈抑制α-葡萄糖苷酶的活性成分,这种活性成分呈现较好的水溶性,可能是具有类似糖结构的成分在起作用,有待于深入研究。
Thirty-seven Douchi samples collected from various regions of China were tested for the inhibitory effects of their water extracts on alpha-glucosidase in vitro.The water extracts from all these Douchi samples could inhibit mouse intestinal alpha-glucosidase to a certainty extent.In addition,samples NO.5 （L.Y）,NO.16 （W.N.H） and NO.21 （M.W） showed stronger inhibitory effect against the enzyme （P〈0.05）.Moreover,microamounts of glucose existing in Douchi samples had less interrupting effect on the anti-hyperglycemic activity of Douchi water extract.This study suggests that there are some active components in Douchi,which can strongly inhibit alpha-glucosidase and present excellent water solubility.These components may have sacchride-like structures.However,this needs to be deeply investigated.
