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。

Abstract:

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 plantsfor the first time.
