瑞香烷型二萜类化合物具有良好的抗肿瘤生理活性. 为了进一步研究该类抗肿瘤活性成分, 对富含瑞香烷型二萜的芫花花蕾进行化学成分研究, 从中分离得到一个巴豆烷型二萜1和两个瑞香烷型二萜原酸酯2和3. 应用多种波谱学方法(1H NMR, 13C NMR, HSQC, HMBC, NOESY, ESI-MS, HR-ESI-MS等), 确定了3个化合物的结构, 化合物1和2为新化合物, 化合物1被鉴定为12-O-(2E,4E-decadienoyl)-4-hydroxyphorbol-13-acetyl. 化合物2被鉴定为化合物3(芫花酯乙)的12位酰基烯烃链的顺式异构体, 命名为异芫花酯乙.

Daphnane-type diterpenes showed potent anti-tumour activities, the flower buds of Daphne genkwa which was rich in daphnane-type diterpenes were subject to phytochemical investigation resulting in the isolation of two novel diterpenes (1, 2) and a known diterpene 3, they were elucidated as 12-O-(2E,4E-decadienoyl)-4-hydroxyphorbol-13-acetyl (1), isoyuanhuadine (2) and yuanhuadine (3) by spectroscopic data, including 1H NMR, 13C NMR, HSQC, HMBC, NOESY, ESI-MS and HR-ESI-MS. The new compound isoyanhuadine is yuanhuadines cis-isomer.

Key words: the flower buds of Daphne genkwa, structure elucidation, 12-O-(2E,4E-decadienoyl)-4- hydroxyphorbol-13-acetyl, isoyuanhuadine, yuanhuadine
