摘要: 收集全国不同地区传统发酵生产的豆豉样品,综合评价其水提物对小鼠肠道内α-葡萄糖苷酶抑制活性,分析豆豉样品中的营养功能成分,揭示不同地区生产的豆豉样品所具有降糖活性的差异。结果表明:中国传统发酵豆豉水提取物具有一定程度的α-葡萄糖苷酶的抑制活性,其中三种豆豉样品(万年红豆豉、美味豆豉、浏阳球哥豆豉)水提物的α-葡萄糖苷酶抑制活性显著高于其他样品(p<0.05)。此外,对豆豉样品中各种营养活性成分的分析结果显示,豆豉样品水提物的α-葡萄糖苷酶抑制活性与样品中糖类物质成分含量的多少密切相关,表明豆豉中存在的α-葡萄糖苷酶抑制剂可能是一种糖类物质或者具有糖链结构的成分。全国各地不同产地、来源豆豉的降糖活性的差异显示,豆豉中降血糖活性因子的产生与其发酵条件、微生物、辅料等因素均可能相关。

Abstract: The water-extracts of some douchi samples, collected from various regions of China, were assayed for its anti-α-glucosidase activity. The nutrients in douchi were also analyzed in order to discuss different anti-hyperglycemic activity of various douchi samples. The results indicated that aqueous douchi, traditionally fermented in China, showed an anti-α-glucosi-dase activity. Among them, there were three samples (WNH douchi, MW douchi and LY douchi) expressed stronger α-glucosidase inhibitory activity than other samples(p<0.05). Moreover, through determining the nutrients contents in douchi, it was found that the anti-α-glucosidase activity of douchi water-extract was closely related to the carbohydrate contents in douchi samples. The results indicated that this kind of α-glucosidase inhibitor is probably carbohydrate or some compound with carbohydrate structure. Besides, the anti-α-glucosidase activities of various douchis were probably related to their fermentation conditions, microorganisms and additives.
