Abstract

From the CH(2)Cl(2) extract of seed kernels of Caesalpinia crista from Myanmar, five new cassane-type diterpenes, caesalpinins MA-ME (1-5), and three new norcassane-type diterpenes, norcaesalpinins MA-MC (6-8), have been isolated, together with 12 known cassane-type diterpenes, 14(17)-dehydrocaesalmin F, caesaldekarin e, caesalmin B, caesalmin C, caesalmin E, 2-acetoxy-3-deacetoxycaesaldekarin e, 2-acetoxycaesaldekarin e, caesalpinin C, 7-acetoxybonducellpin C, caesalpinin E, norcaesalpinin B, and 6-acetoxy-3-deacetoxycaesaldekarin e. The structures of the isolated compounds were elucidated by analysis of their spectroscopic data.

摘要

从缅甸苏木种子仁的二氯甲烷提取物中，分离出了5个新的决明烷型二萜类化合物，即苏木素MA - ME（1 - 5），以及3个新的降决明烷型二萜类化合物，即降苏木素MA - MC（6 - 8），同时还分离出12个已知的决明烷型二萜类化合物，14(17)-脱氢苏木胺F、苏木醛卡林e、苏木胺B、苏木胺C、苏木胺E、2-乙酰氧基-3-脱乙酰氧基苏木醛卡林e、2-乙酰氧基苏木醛卡林e、苏木素C、7-乙酰氧基邦杜塞尔平C、苏木素E、降苏木素B以及6-乙酰氧基-3-脱乙酰氧基苏木醛卡林e。通过对其光谱数据的分析确定了分离得到化合物的结构。
