摘要:目的 建立秦艽中马钱苷酸、獐牙菜苦苷、6′-O-β-D-葡萄糖基龙胆苦苷、龙胆苦苷、獐牙菜苷、异荭草苷和异牡荆苷测定的UPLC方法。方法 采用色谱柱ACQUITY UPLC?BEH C18(50 mm×2.1 mm,1.7μm);流动相甲醇-0.04%磷酸水溶液梯度洗脱,体积流量0.3 m L/min;检测波长242 nm;柱温30℃。结果 马钱苷酸、獐牙菜苦苷、6′-O-β-D-葡萄糖基龙胆苦苷、龙胆苦苷、獐牙菜苷、异荭草苷和异牡荆苷分别在2.100~537.100、1.050~270.000、0.920~236.000、11.100~2 830.000、0.750~192.000、0.167~102.000、0.216~52.800μg进样量与峰面积积分值线性关系良好(r≥0.999 5),平均回收率97.83%~100.08%,RSD≤3.76%。结论 UPLC较HPLC更简便、更有效,可用于秦艽中7种指标成分的同时测定。
Objective An ultra performance liquid chromatographic(UPLC) method was developed for simultaneously determining seven constituents,such as loganic acid,swertiamarin,6′-O-β-D-glucosyl gentiopicroside,gentiopicroside,sweroside,isoorientin,and isovitexin,from the medicinal plants of Gentiana macrophylla.Methods The separation was performed on an Acquity UPLC?BEH C18 column(50 mm ×2.1 mm,1.7 μm) through a gradient elution of methanol-0.04% aqueous phosphorite at a flow rate of 0.3 mL/min.The detection wavelength was 242 nm,and the column temperature was set at 30 ℃.Results For the seven analytes,loganic acid,swertiamarin,6′-O-β-D-glucosyl gentiopicroside,gentiopicroside,sweroside,isoorientin,and sovitexin,a good linearity(r ≥ 0.9995)was obtained in the range of 2.100—537.100,1.050—270.000,0.920—236.000,11.100—2 830.000,0.750—192.000,0.167—102.000,and 0.216—52.800 μg,respectively.Their average recoveries(n = 6) were 97.83%—100.08%,respevtively,with RSD values less than or equal to 3.76%.Conclusion The UPLC method is simpler and more effective than HPLC,and can be used for the simultaneous determination of seven indicative constituents in medicinal plants of G.macrophylla.
