摘要: 采用硅胶色谱柱分离纯化的方法从小槐花药材中分离得到一种黄酮类化合物,根据理化性质及光谱数据鉴定其为异柠檬酚。采用HPLC法对异柠檬酚的含量进行测定,HPLC分析条件如下:色谱柱为Agilent ZORBAX SB-C18(250 mm × 4.6 mm,5 μm),流动相为甲醇-0.2%磷酸水溶液(70:30),流速为1.0 mL/min,检测波长为270 nm,柱温为35 ℃。实验结果表明异柠檬酚在0.011~0.242 μg范围与其峰面积呈良好的线性关系;平均回收率为99.76%,RSD为1.42%(n=6),不同采集地的小槐花药材中异柠檬酚的含量存在一定差异。

Abstract: A flavonoid was isolated from Desmodium caudatum (Thunb.) DC by silica gel column chromatography. The structure of the isolated compound was elucidated on the basis of spectral characteristics and identified as yukovanol. The content of yukovanol in D.caudatum was determined by HPLC.The chromatographic separation were carried out using the following condition:Agilent ZORBAX SB-C18 column (250 mm × 4.6 mm,5 μm) was used with methanol-0.2% phosphoric acid (70:30) as mobile phases.The flow rate was 1.0 mL/min.The UV detection wavelength was 270 nm and the column temperature was 35 oC.The results showed that the linear range of yukovanol were 0.011-0.242 μg,the yukovanol average recovery as 99.76%,RSD = 1.42% (n=6).Distinct differences were found among D.caudatum samples produced in different places.

Key words: Desmodium caudatum (Thunb.) DC, yukovanol, isolation and purification, HPLC
