摘  要:
目的:建立反相高效液相色谱法同时测定祁连獐牙菜中3种有效成分含量的方法。方法:采用ZORBAX SB-C18(250 mm×4.6 mm,5μm)色谱柱,流动相甲醇和水(含0.04%磷酸)的比例在0~20 min内由20∶80至30∶70梯度洗脱,流速1 ml/min,检测波长240 nm,柱温35℃。结果:落干酸、獐牙菜苦苷、龙胆苦苷与其他成分达到基线分离。线性范围分别为0.05~0.625μg(r=0.999 9)0、.009 5~2.9μg(r=0.999 8)和0.048 6~2.56μg(r=0.999 6),加标回收率分别为103%(3.9%)、98.2%(4.0%)、101%(3.5%)。结论该方法简便、快速,结果准确、可靠。

摘  要:
The objective of the research was to establish a quantitative method of simultaneously determination of loganic acid,swertiamarin and gentiopicroside in Swertia przewalskii with RP-HPLC.The samples were separated in the column of Zorbax SB-C18(250 mm×4.6 mm,5 μm),which eluted with methanol and water(0.04% phosphoric acid).The ration of methanol and water was increased from 20∶80 to 30∶70 in 20 min with a detected wavelength of 240 nm,the flowing rate of 1 ml/min,column temperature of 35 ℃.The result indicated three conpounds were isolated.The linear range of loganic acid,swertiarnarin and gentiopicroside were 0.05~0.625 μg(r=0.999 9),0.009 5~2.9(r=0.999 8)and 0.048 6~2.56 μg(r=0.999 6),respectively.The average recoveries were 103%(3.9%),98.2%(4.0%) and 101%(3.5%),respectively.
