目的鉴定醋柳黄酮中的β-谷甾醇(Sito)及其β-D-葡萄糖苷(SitoG),并测定其含量。方法采用TLC法鉴定醋柳黄酮中的Sito及其SitoG;采用RP-HPLC法测定其中的SitoG,色谱柱为Diamonsil C18(150 mm×4.6 mm,5μm),流动相为100%甲醇,流速为1.0 ml.min-1,检测波长为205 nm,标准曲线法定量。结果醋柳黄酮中含有Sito和SitoG,后者的含量为3.1%~3.8%。结论所用方法可用于醋柳黄酮及其制剂的质量控制。
OBJECTIVE To identify and quantitate β-sitosterol(Sito) and β-sitosterol-β-D-glycoside(SitoG) in total flavones of Hippophae rhamnoides(TFH).METHODS TLC method was utilized to identify Sito and Sito G in TFH.The Sito G was determined by RP-HPLC.The mobile phase of pure methanol was delivered at a flow rate of 1.0 ml·min-1.The Diamonsil C18(150 mm×4.6 mm,5 μm) column was maintained at 35℃,and the detective wavelength of the UV detector was set at 205 nm.The SitoG concentration was calculated with the standar...
