摘要
目的:建立露源胶囊的质量标准。方法:采用TLC法对主要成分枸杞子、女贞子等进行定性鉴别;采用HPLC法测定制何首乌中有效成分2,3,5,4'-四羟基二苯乙烯-2-O-β-D-葡萄糖苷的含量,色谱柱:Agilent Eclipse XDB-C_(18)(250 mm×4.6 mm,5μm),流动相:乙腈-水(20∶80),流速:0.6 ml·min^(-1),检测波长:320 nm,柱温:35℃,进样量:5μl。结果:TLC色谱斑点清晰,在与对照药材或对照品色谱相应的位置上,显相同颜色的荧光主斑点,阴性样品无干扰;制何首乌中有效成分2,3,5,4'-四羟基二苯乙烯-2-O-β-D-葡萄糖苷线线性浓度为0.184~1.840μg(r=1.000 0),平均回收率为102.0%,RSD为1.1%(n=5)。结论:本方法操作简便,专属性高、重复性好,可作为露源胶囊的质量控制方法。
Objective： To establish the quality standard for Luyuan capsules. Methods： The two main herbs in the preparation, wolPDerry and ligustrum were identified by TLC qualitatively. The content of 2,3,5,4＇- four hydroxy two styrene -2- O-β-D - glucoside in amultiflorum was determined by HPLC. The chromatographic separation was carried out by using an Agilent Eclipse XDB-C18 （251） mm × 4.6 mm,5 μl）column. The mobile phase consisted of acetonitrile-water （20：80） with gradient elution at a flow rate of 0.6 ml min-1 , and the injection volume was 5 μl. The detection wavelength and column temperature was 320 nm and 35 ℃ ,respeetively. Results： The characteristics under a microscope were ohvious. The spots in TLC were clear without any interference. The linear range of 2,3,5,4＇- four hydroxy two styrene -2- O-β-D - glueoside was 0.184-1. 840 ℃g（ r = 1. 000 0）. The average recovery was 102.0% and RSD was 1.1% （n = 5）. Conclusion： The method is simple with high specificity and good repeatability, whleh can he used as the quality control method of Luyuan capsules.
