摘要: 从乌墨( Syzygium cumini) 根的甲醇提取物中分离鉴定8 个已知化合物, 并对其进行了经高糖、高胰岛素处理后胰岛素抵抗L6 肌管细胞糖摄取活性的筛选。初步研究结果表明, 其中7 个化合物在有无胰岛素刺激下均能明显促进葡萄糖的利用。在无胰岛素刺激状态下, 浓度为10μg ml-1 时, 无羁萜(1) 的葡萄糖消耗量比抵抗细胞增加了17.35% ; 在有胰岛素刺激状态下, 浓度为0 . 1μg ml-1 , 5 , 7 , 3′, 4′, 5′-五羟基黄酮(8) 葡萄糖消耗量比抵抗细胞增加了51.11%。

Abstract: Eight known compounds isolated from the roots of Syzygium cumini were evaluated for their ability to enhance the glucose consumption in insulin-resistant L6 muscle cells induced by high concentration-insulin and glucose . All of compounds significantly enhanced the glucose consumption of insulin-resistant cells in the presence and absence of insulin. The glucose consumption was increased 17.35% and 51.11% by compound 1 ( friedelin) at a concentration of 10 μg ml-1 without insulin and by compound 8 (5 , 7 , 3′, 4′, 5′-pentahydroxyflavone) at a concentration of 0 . 1μg ml - 1 with insulin, respectively .
