摘要
目的:建立中药茺蔚子中盐酸水苏碱的高效液相色谱-蒸发光散射检测器测定方法。方法 Asahipak NH2P 504E色谱柱(4.6 mm×250 mm),流动相为乙腈-0.2%磷酸溶液(84:16),体积流量1 mL/min,柱温30℃。结果盐酸水苏碱在0.487~4.383μg范围内线性关系良好,r=0.9999,平均回收率为97.96%,RSD为0.92%。结论该法灵敏度高,专属性强,可作为中药茺蔚子中盐酸水苏碱的定量测定方法。
Objective To establish HPLC-ELSD determination method of the hydrochloric acid stachydrine in Mother-wort Fruit. Methods The separation by HPLC-ELSD was performed on Asahipak NH2P 50 4E column (4.6 mm×250 mm) with acetonitrile-0.2% phosphoric acid solution (84:16) as mobile phase, 1 mL/min of flow rate and 30℃ of column temperature. Results Hydrochloric acid stachydrine at 0.487-4.383μg had good linear relationship, r=0.9999, the av-erage recovery was 97.96%, RSD was 0.92%. Conclusion The method is sensitive, specific, it can be used as quantita-tive determination method of the hydrochloric acid stachydrine in Motherwort Fruit.
