摘要: 在体外比色法观察大豆胚轴提取物对大鼠小肠黏膜蔗糖酶和麦芽糖酶活性的影响,并用快速过滤法观察其对兔小肠刷状缘囊泡葡萄糖转运活性的影响。结果表明,大豆胚轴提取物明显降低大鼠小肠蔗糖酶、麦芽糖酶活性和兔小肠刷状缘囊泡葡萄糖转运能力。提示,大豆胚轴提取物可延缓小肠对糖的消化和吸收,经常食用可能有助于延缓餐后血糖的持续升高。

Abstract: The effect of soybean hypocotyl extract on sucrase and maltase activity of rat intestinal mucosa was investigatedby colorimetric method, and glucose uptake into brush border membrane vehicles were determined by a rapid filtration method.The results showed that soybean hypocotyl extract significantly decreased sucrase and maltase activities of rat intestinal mucosaand glucose transport potency of brush border membrane vehicle of rabbit small intestine. It is suggested that soybean hypo-cotyl extract, which inhibit carbonhydrate digestion and absorption into small intestine, seem physiologically useful for sup-pressing postprandial hyperglycemia.

Key words: soybean hypocotyl, sucrase, maltase, glucose transporter
