摘 要:采用反相高效液相色谱(RP-HPLC)的方法对狭叶松果菊组培苗不同部位、愈伤组织以及不同株系毛状根中的松果菊苷和绿原酸进行了含量测定,建立同时测定狭叶松果菊组织培养物中松果菊苷和绿原酸含量的高效液相色谱方法;实验采用Kromasil ODS C18柱,流动相为乙腈∶甲醇∶0.1%磷酸溶液(10∶15∶75);检测波长为330nm。结果表明松果菊苷和绿原酸在0~25μg/mL范围线性关系良好;平均回收率方面松果菊苷为97.6%(RSD=0.83%),绿原酸为98.5%(RSD=0.91%)。该法简便、准确,可作为狭叶松果菊组织培养物中松果菊苷和绿原酸的定量分析方法。A high performance liquid chromatographic (HPLC) method was developed to determine the contents of chlorogenic acid and echinacoside in Echinacea angustifolia. The separation was performed on an Kromasil ODS C18 column (150 mm× 4.6 mm, 5 μm) operated at normal temperature with the gradient elution by three mobile phases including methanol (A) , acetonitrile (B) and water (C including 0.1% phosphate (v/v)) at a flow rate of 1 mL/min. The detection wavelength was set at 330 nm. The cali- bration curve was linear over the concentration range of 1.0-25 ug/mL The relative recoveries of echinacoside and chlorogenie acid were 97. 6% (RSD=0. 83%) and 98.5% (RSD=0. 91%) respectively. This method is simple, rapid and highly sensitive. It is suitable for the simultaneous determination of ehlorogenic acid and echinacoside in tissues of E. angustifolia.
