Figure 2. Analysis of polyphenols was done with HPLC-PDA (diode array detector). This detector enables polyphenols to be scanned at different wavelengths. In the present work, we used 329 nm (the blue line) for caffeoylquinic acids and 352 nm (the black line) for flavonoids. (A) Chromatogr...
本文以中国药典的HPLC方法为起点,利用快速高分离度液相色谱(RRLC)对西洋参中活性组分Rg1、Re、Rb1进行快速、有效的分离。该方法在保持分离度和重现性的前提下,改善了分析灵敏度,大大缩短了分离时间。另外,使用相同RRLC系统和与RRHT色谱柱相同键合相的ZORBAX SB C18 HPLC色谱柱,也获得了满意的HPLC分离结果。
