摘 要:研究了用反相高效液相色谱法(HPLC)测定茶皂素含量的方法,以VP-ODS(250 mm×4.6 mm,C18,5 μm)作分析柱,以甲醇-水(v∶v=9∶1)作流动相,流速控制在1.0 mL/min,检测波长280 nm,以质量浓度为横坐标,峰面积为纵坐标,得到工作曲线为Y=3.02×106X-1.16×104,线性相关系数为0.999 5。回收率为97.02%~102.82%。通过反相高效液相色谱法测定茶籽饼中粗茶皂素的含量为11.89%。

Abstract:A reverse-phase high performance liquid chromatography (HPLC) method for determination of tea saponin extracted from tea-seed pancake with Soxhlet was studied. With the column VP-ODS(250 mm×4.6 mm,C18,5 μm) and mobile phase methanol-water(v∶v=9∶1)at flow-rate of 1.0 mL/min,a linear equation was obtained as Y=3.02×106X-1.16×104,where Y represents peak area and X represents mass concentration. Linear correlation coefficient r was 0.999 5. Under these conditions,the recovery rate of tea saponin was 97.02%~102.82%.
Key words:reverse-phase high performance liquid chromatography;tea saponin;camellia oleifera
