A new diterpene orthoester, Yuanhuadine C32H43O10, M+m/z 686.2790, [a]D16.5+26.9°(c.0.046 OHCl3) 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, C36H46O10, M+m/z 626.3083, m.p.173-175℃, whioh was identified as 8 by direct oomparision with the authentio specimen obtained from yuanhuaoine (2) via its debenzoylation product 6, and the aoetnnide 6, followed by aoetylation of the C12H-OH group.Both 1 and 2 show a signifioant abortificient activity.
