Abstract

Three lanostanoids, 3beta-methoxycycloartan-24(24(1))-ene (1), 3beta,23beta-dimethoxycycloartan-24(24(1))-ene (2), and 3beta,23beta-dimethoxy-5alpha-lanosta-24(24(1))-ene (3), were isolated from the leaves of Amentotaxus formosana. The structures of new compounds 2 and 3 were determined by NMR and MS studies, and the structure of 3 was further confirmed by X-ray crystallographic analysis.

摘要

从台湾穗花杉的叶子中分离出了三种羊毛甾烷型化合物，3β-甲氧基环阿尔廷-24(24(1))-烯（1）、3β,23β-二甲氧基环阿尔廷-24(24(1))-烯（2）和3β,23β-二甲氧基-5α-羊毛甾-24(24(1))-烯（3）。通过核磁共振（NMR）和质谱（MS）研究确定了新化合物2和3的结构，化合物3的结构通过X射线晶体学分析进一步得到证实。
