【摘要】 建立了藏药麻花艽中龙胆苦苷(gentiopicroside)、落干酸(loganic acid)、獐牙菜苦苷(swertiamarin)和獐牙菜苷(sweroside)4种苦苷类成分的HPLC分析方法。色谱柱为Eclipse XDB-C8(4.6 mm i.d.×150 mm,5μm),流动相为体积分数5%乙腈+10 mmoL甲酸~95%乙腈水溶液,检测波长为240 nm。结果表明,该方法具有良好的线性关系和回收率,为麻花艽中苦苷类成分的进一步开发利用提供了科学依据。更多还原

【Abstract】 The contents of four iridoids（gentiopicroside,loganic acid,swertiamarin,sweroside） in Gentiana straminea were determined by high performance liquid chromatography（HPLC）.The analysis was performed on Eclipse XDB-C₈（4.6 mm i.d.×150 mm,5 μm） column,eluted with the solution of 0.01 mol/L methanoic acid with 5% acetonitrile and 95% acetonitrile and with UV detection at 240 nm.All calibration curves indicated good linear regression（r≥0.9999） within test ranges.更多还原
