【摘要】 从马缨丹（Lantana camara L.）根中分离到八个三萜成分,通过光谱(UV,IR,¹HNMR,¹³CNMR,MS)分析和理化常数测定,分别鉴定为lantanolic acid（Ⅰ）,22β-O-angeloyl-lantanolic acid（Ⅱ）,oleanolic acid（Ⅲ）,22βO-angeloyt-oleanolic acid（Ⅳ）,22β-O-senecioyl-oleanolic acid（Ⅴ）,22β-hydroxy-oleanolic acid（Ⅵ）,19α-hydroxyursolic acid（Ⅶ）,3β-isovaleroyl-19α-hydroxyursolic acid（Ⅷ）。Ⅱ系首次从植物中分离到。Ⅷ是新化合物,命名为lantaiursolic acid。更多还原

【Abstract】 Eight triterpenoids were isolated from the roots of Lantana camara. On the basis of their chemical properties and spectral data (UV, IR, MS, ¹HNMR, ¹³CNMR), they were identified as lantanolic acid （Ⅰ）, 22β- O- angeloyl- lantanolic acid （Ⅱ）, oleanolic acid （Ⅲ）, 22β-O- angeloyl-oleanolic acid （Ⅳ）, 22β- O- senecioyl- oleanolic acid （Ⅴ）, 22β- hydroxy- oleanonic acid （Ⅵ）, 19α-hydroxy-ursolic acid（Ⅶ） and 3β-isovaleroyl-19α-hydroxy-ursolic acid （Ⅷ）. Ⅱ was obtained for the first time from plant. Ⅷ is a new compound named lantaiursolic acid.更多还原
