STUDIES ON THE ACTIVE PRINCIPLES OF THE ROOT OF YUAN-HUA (DAPHNE GENKWA) Ⅱ. ISOLATION AND STRUCTURE OF A NEW ANTIFERTILE DITERPENE YUANHUADINE
【摘要】 从瑞香科植物芫花的根中分得另一个新的二萜原酸酯——芫花酯乙,根据物理及化学数据将其结构定为1,并由芫花酯甲(2)经三步化学反应生成1的丙酮缩合物3。
【Abstract】 A new diterpene orthoester, Yuanhuadine C32H42O10, M+m/z 586.2790, [a]D16.5+26.9°(c. 0.045 CHCl3)was isolated from the root of Daphne genkwa Sieb. et Zucc. (Thymelaeaceae). Its struoture was elucidated as 1 by spectral analyses and chemical transformations.The aoetonide of 1 was obtained as prismatio orystals, C35H46O10, M+m/z 626.3083, m. p. 173~175℃, whioh was identified as 3 by direct oomparision with the authentic specimen obtained from yuanhuaoine (2) via its debenzoylation product 5, and the aoetonide 6, followed by aoetylation of the C12-OH group.Both 1 and 2 show a significant abortificient activity.
