摘　　要：采用硅胶、MCI和Sephadex LH-20层析方法对团花树皮的化学成分进行分离纯化,运用现代波谱技术鉴定了10个化合物:4-carboxy-3-hydroxy-5-methylphenyl 3-methoxy-4-hydroxy-5-methylbenzoate(1),谷甾醇-3-O-(6'-O-棕榈酰基)-β-D-葡萄糖苷(2),喹诺酸-3-O-α-L-鼠李糖苷(3),clethric acid(4),常春藤苷元(5),钩藤苷元C(6),morolic acid(7),咖啡酸甲酯(8),卡丹宾(9)和3α-二氢卡丹宾(10)。其中化合物1为一个新的酚性成分,化合物2～8首次从该属植物中分离得到。Ten compounds were isolated and purified from the bark of Anthocephalus chinensis by column chromatography on silica gel,MCI and Sephadex LH-20,and their structures were elucidated as 4-carboxy-3-hydroxy-5-methylphenyl 3-methoxy-4-hydroxy-5-methylbenzoate（1）,sitosterol-3-O-（6′-O-palmityl）-β-D-glucoside（2）,quinovic acid-3-O-α-L-rhamnopyranoside（3）,clethric acid（4）,hederagenin（5）,uncargenin C（6）,morolic acid（7）,caffeic acid methyl ester（8）,cadambine（9）,and 3α-dihydrocadambine（10） by modern spectroscopic methods.Compound 1 was a new phenolic compound,and compounds 2-8 were obtained from Anthocephalus plants for the first time.
