从楝科（Meliaceae）的木材中分离出五种新化合物，即阿朴蒂鲁卡洛衍生物 (1)、(9)、(13) 和 (16) 以及四降三萜类维拉辛素 1,3-二乙酸酯 (18)。从同一棵树的种子中获得了 4 种新的四降三萜类化合物，包括 γ-内酯 (22)、半缩醛 (23)、γ-羟基丁烯内酯 (24) 和 17.β.-羟基-6.α.-乙酰氧基宁宾宁 (26)。化合物(22)和(23)可能是正常呋喃类四降三萜类化合物的前体。报告了这 9 种化合物的 13C 和 1H NMR 数据。
Five new compounds, the apo-tirucallol derivatives (1), (9), (13) and (16) and the tetranortriterpenoid vilasinin 1,3-diacetate (18) were isolated from the wood of C. paniculatus (Meliaceae). From the seeds of the same tree 4 new tetranortriterpenoids were obtained, including the .gamma.-lactone (22), the hemiacetal (23), the .gamma.-hydroxybutenolide (24) and 17.beta.-hydroxy-6.alpha.-acetoxynimbinin (26). Compounds (22) and (23) are possible precursors of normal furanoid tetranortriterpenoids. 13C and 1H NMR data for these 9 compounds are reported.
