(Z)-1-[3'-(4'',8''-dimethylnona-3'',7''-dienyl)cyclohex-3'-enyl]-2,4,5-trimethoxybenzene (2), a phenylpropanoid 1,2,4-trimethoxy-5-(1-methoxy-ethyl)-benzene (3), and an aporphine alkaloid N-acetylpachypodanthine (4), were isolated in addition to several known compounds from cyclohexane, dichloromethane and alkaloid extracts from bark of Pachypodanthium confine. The structures of these compounds were established
两个倍半萜烯-三甲氧基苯乙烯缀合物 (E)-1-[3'-(4'',8''-二甲基壬二烯-3'',7''-二烯基)环己-3'-烯基]-2,4,5-三甲氧基苯 (1) 和 (Z)-1-[3'-(4'',8''-dimethylnona-3'',7''-dienyl)cyclohex-3'-enyl]-2,4,5-三甲氧基苯 (2)、苯丙素 1,2,4-三甲氧基-5-(1-甲氧基-乙基)-苯 (3) 和阿朴啡生物碱 N-乙酰基胡丹碱 (4),除了几种已知的化合物之外从 Pachypodanthium confine 树皮中提取的环己烷、二氯甲烷和生物碱提取物。这些化合物的结构是基于对它们的高分辨率 NMR(HSQC、HMBC、COZY 和 NOESY)光谱数据的解释而确定的。
