反相高效液相法测定枳实、枳壳中橙皮甙和柚皮甙的含量

 采用高效液相法测定了枳实和枳壳中的橙皮甙和柚皮甙含量。柱为HypersilODS1柱(250mm×4 6mmi d ),流动相为乙腈 0 5%乙酸溶液(体积比为22∶78),流速为1 0mL/min,检测波长为283nm。柚皮甙和橙皮甙的线性范围分别为0 060g/L～0 604g/L和0 0125g/L～0 125g/L,柚皮甙和橙皮甙的平均回收率分别为97 1%和95 3%。该方法具有操作简便、分析快速、准确等优点。

Determination of Hesperidin and Naringin in Fructus Aurantii Immaturus and Fructus Aurantii by Reversed-Phase High Performance Liquid Chromatography

An HPLC method was established for the determination of hesperidin and naringin in the Fructus Aurantii Immaturus and Fructus Aurantii from different places. Hesperidin and narigin were separated on a Hypersil ODS1 column with acetonitrile-0.5% acetic acid (volume ratio of 22:78) as the mobile phase and detected at 283 nm. The flow rate was 1.0 mL/min. The column temperature was set at 35 degrees C. The calibration curves were linear in the ranges of 0.060 g/L-0.604 g/L and 0.0125 g/L-0.125 g/L for naringin and hesperidin respectively. The average recoveries were 97.1% for naringin and 95.3% for hesperidin. The method is simple, rapid, accurate and reliable.
