摘要
目的建立HPLC—ELSD同时测定不同产地青蒿中青蒿素的含量。方法采用色谱柱:LichrospherC18柱(4.6mm×250mm,5μm);流动相:甲醇:水(75:25);Alltech ELSD 2000(蒸发光散射检测器)检测,气体为高纯氮气,流速2.0L/min。结果在此色谱条件下,青蒿素与其它色谱峰完全达到基线分离(R〉2.0)。12批不同产地黄花蒿中青蒿素含量在0.25%~1.21%。结论用该方法进行检测,操作简单,灵敏度高。
Objective To establish a method to quantify the artemisinin in Artemisia annuan L. from different regions. Methods Separtion was performed in a chromatographic column : Lichrosper C18 (4.6 mm × 250 mm,5μm ) , and mobile phase consisted of : Methyl alcohol:water(75:25 ) . Alltech ELSD 2000 (electronic light scattering detector)was used. Results Under this chromatographic condition the baseline totally disunited between the peak of artemisinin and other chromatographic peaks . The quantity of artemisinin in twelve batches Artemisia annua L. in different regions is between 0.25% - 1.21%. Conclusion This method is sensitivity and convenient for dertermination of artemisinin.
