HPLC法同时测定益骨颗粒中3种成分的含量
Simultaneous Determination of Three Components in Yigu Granules by HPLC
【摘要】 目的建立同时测定益骨颗粒中淫羊藿苷、龙胆苦苷、马钱苷酸3种成分含量的方法。方法采用高效液相色谱法(HPLC),色谱柱为Agilent Eclipse Plus C18(250 mm×4.6 mm,5μm),流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为1.0 mL·min-1,检测波长为254 nm,柱温为25℃,进样量为10μL。结果淫羊藿苷、龙胆苦苷、马钱苷酸3种成分的检测质量浓度线性范围分别为4.072101.8,20.252506.3,4.044101.1μg·mL-1(r=0.999 9),平均回收率分别为99.51%、98.74%、98.77%,RSD分别为1.16%、1.02%、1.79%(n=6)。结论该测定方法操作简便、结果准确、重复性及专属性好,可用于益骨颗粒的质量控制。
【Abstract】 OBJECTIVE To establish a method for simultaneous determination of icariin,gentiopicroside and loganic acid in Yigu granules. METHODS HPLC was performed on the column of Agilent Eclipse Plus C18( 250 mm×4.6 mm,5 μm) with mobile phase ofacetonitrile-0.1% phosphoric acid( gradient elution) at a flow rate of 1.0 mL ·min-1,the detection wavelength was 254 nm,column temperature was 25℃,and the injection volume was 10 μL. RESULTS The linear range was 4. 072- 101. 8 μg·mL-1 for icariin( r = 0.999 9),20.252-506.3 μg·mL-1 for gentiopicroside( r = 0.9999),4.044-101.1 μg·mL-1 for loganic acid( r = 0.999 9),respectively. The average recoveries were 99.51%( RSD = 1.16%,n = 6),98.74%( RSD = 1.02%,n = 6),98.77%( RSD = 1.79%,n = 6),respectively. CONCLUSION The method is simple and accurate with good repeatability and specificity,and could be used for the quality control of Yigu granules.
