食用土当归中齐墩果酸含量分析

Analysis of Oleanolic acid content of Aralia cordata Thunb

食用土当归（Ａｒａｌｉａ ｃｏｒｄａｔａ Ｔｈｕｎｂ）在我国分布较广，资源较丰富，民间早作为蔬菜食用。为寻求新的药物资源，本文用薄层层析法和反相高效液相色谱法对食用土当归的化学成分进行了分析，并用薄层层析法一分光光度法测定了齐墩果酸（Ｏｌｅａｎｏｌｉｃ ａｃｉｄ）的含量为２．６％。

For the purpose of exploitationg new medicinal resources,Chemical constituents of the plant ware analyzed by Thin layer Chromatographay and reversed phase high preformance liquid Chromatography. And analysis of Oleanolic acid content of Aralic cordata Thunb by Thin Layer Chromatography-Spec- trophotometric Methods. It showed that the content of Oleanolic acid is 2.6%.
