摘要
目的建立白头翁汤中白头翁皂苷B4含量测定的RP-HPLC法。方法采用HypersilC18色谱柱(250mm×4.6mm,5μm),以乙腈-水(体积比28:72)为流动相,流速为1.0mL·min^-1,检测波长205nm,柱温30℃,进样量10μL。结果白头翁皂苷B4质量浓度在0.1—1.5g·L^-1内线性关系良好(r=0.9998);平均加样回收率为103.1%,RSD为1.2%(n=9);重复性RSD为1.6%(n=5)。结论该方法简便、快速、准确、重现性好,为白头翁汤及其新剂型改进提供了一种质量控制方法。
Objective To establish an RP-HPLC method for the determination of pulchinenoside B4 in Pul- satillae( traditional Chinese medicine) decoction. Methods Chromatagraphy was performed on a Hypersil C18 column (250 mm×4.6 mm,5μm) at 30℃ and 205 nm. The mobile phase was acetonitrile-water (V: V = 28: 72, ) at a flow rate of 1.0 mL·min-l. Results The calibration curve was linear in the range of 0.1 - 1.5 g· L^-1 ( r = 0. 999 8 ) ; The average recovery was 99.0% and RSD was 1.6% ( n = 9 ) ;The RSD of re- producibility was 1.6 % ( n = 5 ). Conclusions The method is simple, accurate with good reproducibility. It can provide a method of quality assessment for Pulsatillae decoction.
