从黄花败酱根茎中用柱层析方法分离出一单体化合物，经化学反应和光谱分析鉴定为齐墩果酸－3－β－0－α－L－鼠李吡喃糖基（1→2）－α－L－阿拉伯吡喃糖甙，即β-常春藤素（β-hederin）．
A monomer compound was isolated by column chromatography from the rhizome of Patrinia dahurica and identified as oleanolic acid-3-β-0-α-L-rhamnopyranosyl by chemical reaction and spectroscopic analysis (1 → 2) -alpha-L-arabinopyranoside, ie, β-hederan.
