HPLC-ELSD联用检测白头翁汤中白头翁皂苷B4的含量
摘要
目的:建立HPLC-ELSD检测白头翁汤中白头翁皂苷B4含量的方法。方法:采用Agilent Ecilpse XDB-C18色谱柱(4.6 mm×250 mm
Objective:To establish a method for the deter mination of pulchinenoside B4 in Baitouweng decoction by HPLC-ELSD.Method: A HPLC methods detected by HPLC-ELSD has been developed: Agilent Ecilpse XDB-C18 column(4.6 mm × 250 mm
5 μm) with mobile phase of acetonitrile and water(28∶72);The temperature of the drift tube was set at 100 ℃
the flow rate of gas at 2.8 L·min-1.Result:pulchinenoside B4 in Baitouweng decoction could be deter mined by HPLC-ELSD.The line arrange of pulchinenoside B4 was 1.156-10.404 μg.The recovery was 98.9%(n = 5
RSD 0.7%).Conclusion:The method is simple and accurate
with good repeatability
and can be used for deter mination of pulchinenoside B4 in Baitouweng decoction.
