摘要 目的: 建立不同海拔蒙药新疆假龙胆中3种有效成分的RP-HPLC测定方法。方法: 采用ZORBAX SB-C18柱(4.6 mm×250 mm,5 μm)色谱柱,流速1.0 mL·min-1,獐牙菜苦苷、龙胆苦苷的流动相为甲醇-水(20:80),芒果苷的流动相为甲醇-0.5%乙酸(25:75),检测波长分别为獐牙菜苦苷238 nm,龙胆苦苷270 nm,芒果苷254 nm,柱温25℃。结果: 实验所建立的测定方法简便准确,在1 900~3 035 m的不同海拔的新疆假龙胆中獐牙菜苦苷、龙胆苦苷、芒果苷的含量变化范围分别是1.30%~2.48%,0.377%~0.508%,0.041%~0.071%。结论: 不同海拔的新疆假龙胆中3种有效成分含量随海拔高度增高均呈增加趋势。 Objective: To establish a RP-HPLC method for the determination of three kinds effective compositions in Mongolian medicine Gentianella turkestanorum from different elevation. Method: A Zorbax SB-C18(4.6 mm×250 mm,5 μm) column was used with methnol-water(20:80) and methnol-0.5%acetic acid(25:75) at detection wavelengths of 238,270 nm and 254 nm for swertiamarin, gentiopicrin and mangiferin. The flow rate was 1.0 mL-1·min-1 and the column temperature was 25℃. Result: The method is simple and accurate. In Gentianella turkestanorum from 1 900-3 035 m, the changes of swertiamarin,gentiopicrin and mangiferin were 1.30%-2.48%,0.377%-0.508%,0.041%-0.071%(g·g-1). Conclusion: Three kinds effective compositions in Gentianella turkestanorum were increased with the increase of elevation.
