摘要
目的:建立反相高效液相色谱法测定紫红獐牙菜药材中3种苷类成分含量的方法。方法:色谱柱为Alltimal C18柱(4.6 mm×250 mm,5μm),流动相为甲醇-水(水中含0.05%磷酸),梯度洗脱,流速1 mL.min-1,检测波长254 nm,柱温30℃。结果:龙胆苦苷(gentiopicroside),芒果苷(mangiferin),8-O-β-D-吡喃葡萄糖基-1,5-二羟基-3-甲氧基酮(swertrianolin)分别在31.3~281.7,0.31~2.78,0.55~4.91μg内线性关系良好,相关系数分别为0.999 6,0.999 3,0.999 5;平均回收率分别为103.36%,101.42%,97.39%,RSD均小于3%(n=5)。结论:该方法操作简便,分离度好,为完善紫红獐牙菜药材的质量标准提供了依据。
To develop a RP-HPLC method for determination of three glycosides in Swertia punicea. Method: Chromatographic column: Alhimal C18 (4. 6 mm × 250mm, 5 μm). Mobile phase: methanol-water ( including 0.05% H3PO4) , and gradient elution. Flow rate : 1 mL·min^-1. Wavelength : 254 nm. Column temperture: 30℃. Result: The calibration curves of gentiopicroside, mangiferin and swertrianolin were in good linearity over the range of 31.3-281.7, 0. 31-2.78, 0. 55-4.91μg, ( r = 0. 999 6, 0. 999 3, 0. 999 5). The average recoveries were 103.36%, 101.42% and 97.39% , with RSD less then 3% (n = 5). Conclusion: It is a simple and sensitive meathod in controlling the quality of S. punicea.
