文摘	采用反相高效液相色谱法同时分离和测定了龙胆科獐牙菜属的川西獐牙菜和抱茎獐牙菜中几种酮的含量.色谱柱为Kromasil C_(18)(250 mm * 4.60 mm i.d., 5 μm),流动相为甲醇-0.1%的磷酸水溶液(体积比为73∶27),流速1 mL/min,检测波长260 nm,柱温20 ℃.实验结果表明,该方法具有很好的线性关系与精密度,方法简单、准确、实用性强.
其他语种文摘	A simple and rapid method for simultaneous separation and determination of xan-thones in Swertia mussotii and Swertia franchetiana by high performance liquid chromatogra-phy has been established. The analysis was performed on a Kromasil C18 column (250 mm * 4.60 mm i.d., 5μm) (at 20 ℃) eluted with methanol and 0.1% aqueous phosphoric acid (73: 27 in volume ratio) as mobile phase at a flow rate of 1.0 mL/min and with UV detection at 260 nm. Results showed that xanthones were separated successfully from each other and from other interfering components. There was a good linear relationship between the content of component and its peak area for each xanthone, with the correlation coefficients of 0.999 2 -0.999 9. The convenient method can be used for quantitative analysis of xanthones.
