| الوصف: | 建立HPLC法测定桑叶提取物中水解槲皮素和山萘酚的含量.先用甲醇-盐酸混合液（甲醇终浓度50%,盐酸终浓度2.0 mol •L-1）水解桑叶提取物中的黄酮类成分成槲皮素和山萘酚,以HPLC法测定槲皮素和山萘酚含量.色谱柱为Diamonsil钻石C18柱,流动相为甲醇-0.2%磷酸（63 ：37 ,体积分数）,流速为1.0 mL •min-1,检测波长为370 nm.结果表明槲皮素在0.84~26.8 mg •L -1之间,山萘酚在0.44~14.2 mg •L -1之间呈良好的线性关系,平均回收率分别为101.3%和99.5%.该测定方法准确、重复性好,可用于桑叶提取物中槲皮素和山萘酚的含量测定. |
