The structure of a triterpene alcohol isolated from the nonsaponifiable lipids of both the root and aerial part extracts of Cimicifuga simplex (Ranunculaceae) was established to be cycloarta-16, 24-dien-3β-ol (1). Spectral identity of the 24, 25-dihydro derivative (4) of 1 with 24, 25-dihydrocimicifugenol demonstrated that cimicifugenol, previously assigned the erroneous structure of cycloarta-7, 24-dien-3β-ol, possesses structure 1.
从毛当归(毛茛科)根和地上部分提取物中分离出的非皂化脂质的三萜醇结构被确定为环阿塔-16,24-二烯-3β-醇(1)。1的24,25-二氢衍生物(4)与24,25-二氢毛当归酚的光谱特征表明,之前被错误地确定为环阿塔-7,24-二烯-3β-醇结构的毛当归酚实际上具有1的结构。
