摘要
目的:建立HPLC同时测定麻花秦艽中马钱苷酸、龙胆苦苷、獐牙菜苦苷、獐牙菜苷、山栀苷甲酯含量的方法。方法:采用Diamonsil C18色谱柱(4.6 mm×250 mm,5μm),流动相乙腈-0.05%磷酸水梯度洗脱,流速1.0 m L·min-1,柱温30℃,检测波长240 nm。结果:以上5种环烯醚萜类成分的线性范围分别为0.042 1-8.420 0(r=0.999 7),0.094 2-18.830 0(r=1.000 0),0.012 4-2.471 2(r=0.999 9),0.009 9-1.971 2(r=1.000 0),0.011 3-2.260 0μg(r=0.999 0),平均回收率均在95.39%-103.75%,RSD≤2.6%。结论:该法简便、快速、准确,可以用来同时测定麻花秦艽中5种环烯醚萜苷成分的含量。
Objective: To establish an HPLC method for the determination of loganic acid, gentiopicroside, swertiamarin, sweroside, shanzhiside methylester in Gentiana straminea. Method: The assay was performed on a Diamonsil C18 column (4.6 mm × 250 mm, 5 μm) eluted with acetonitrile-0.05% phosphoric. The detection wavelength was 240 nm, the flow rate was 1.0 mL ·min^-1, and the column temperature was set at 30 ℃. Result: The calibration curves were linear in the ranges of 0. 042 1-8. 420 0 μg ( r = 0. 999 7) for loganic acid, 0.094 2-18.830 0 μg (r = 1.000 0) for gentiopicroside, 0.012 4-2.471 2 μg (r =0.999 9) for swertiamarin, 0.009 9-1.971 2μg (r = 1.000 0) for sweroside, 0.011 3-2.260 0 μg (r =0.999 0) for shanzhiside methylester. The average recoveries were 95.39%-103.75% ( RSD ≤ 2.6% ). Conclusion: The method is simple and accurate for the quality control of G. straminea Radix.
