摘要
目的建立同时测定桑叶中绿原酸、芦丁和木犀草苷含量的方法。方法样品用70%乙醇溶液提取,采用Phenomenex LunaC18色谱柱(4.6mm×250mm,5μm)分离;流动相:0.1%磷酸-乙腈,梯度洗脱;流速:1:0mL·min^-1;检测波长:348nm。结果绿原酸、芦丁、木犀草苷分别在3.048~152.4,1.059~52.96,1.437-71.85μg·mL一内具有良好的线性关系;加标回收率分别为100.4%,98.3%,98.7%;RSD分别为1.7%,2.0%,1.9%(n=9)。结论该方法简单易行,准确性和重复性好,可用于桑叶的质量控制。
OBJECTIVE To determine the content of chlorogenic acid, rutin and luteolin glycosides in mulberry leaves by HPLC. METHODS The sample was extracted by 70% ethanol and separated on a Phenomenex Luna column(4.6 mm × 250 mm, 5 μm). 0.1% Phosphoric acid and acetonitrile was used as mobile phase with gradient elntion at flow rate of 1.0 mL.min^-1 The detection wavelength was set at 348 nm. RESULTS The linear ranges of chlorogenic acid, rntin and luteolin glycosides were 3.048-152.4, 1.059-52.96 and 1.437-71.85 μg.mL^-1. And the average recoveries were 100.4%, 98.3% and 98.7% with the RSD of 1.7%, 2.0%, 1.9%(n=9), respectively. CONCLUSION This method is simple, rapid and with good repeatability, and can be used for the quality control of mulberry leaves.
