摘要
Four neo-lignans: isoamericanin A(1), isoamericanol A(2), americanin B(3), artabotrycinol(4), a hemiterpenoid: (R)-artabotriol(5) and other compounds: palmitic acid(6), β-sitosterol(7) and daucosterol(8) were isolated from the seeds of Artabostrys hexapetalus (L.f.) Bhadari (Annonaceae). Artabotrycinol(4) is a new neo-lignan and (R)-artabotriol(5) is a new hemiterpenoid. Their structures were established by IR, UV, MS, 1D and 2D NMR. Three other neo-lignans 1, 2, 3 were isolated from this plant for the first time.
从药用植物鹰爪种子分得 4个木脂素 :异洋商陆素A (isoamericaninA ,1) ,异洋商陆醇A (isoamericanolA ,2 ) ,洋商陆素B (americaninB ,3) ,鹰爪木脂醇 (artabotrycinol,4)和一个半萜 :(R) 鹰爪三醇 [(R) artabotriol,5 ],以及棕榈酸 (6 ) ,β 谷甾醇 (7)和胡萝卜苷 (8)。根据光谱数据 (IR ,UV ,MS ,1D ,2D NMR)分析 ,确定它们的化学结构。其中 ,鹰爪木脂醇 (4 )是一个新木脂素 ,(R) 鹰爪三醇 (5 )是一个新半萜醇。木脂素化合物 1,2和
