【摘要】 通过对不同溶剂展开体系的选取 ,确定低聚原花青素分离的薄层色谱展开体系为v(甲苯 )∶v(丙酮 )∶v(乙酸 ) =3∶3∶1.从原花青素中分离制备得到儿茶素的单体、二聚体、三聚体 ,运用高效液相色谱对其进行了分析验证 .更多还原

【Abstract】 The separation of Oligomeric Proantho cyanidins (OPC’s) by TLC was studied. After the experiments of various ascending elusions, the chromatography was carried out using an ascending elution with toluene/acetone/acetic acid (3∶3∶1). HPLC was also employed to analyze the compose of each fraction obtained from TLC.更多还原
