摘要: 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, 23是首次从该植物分得。

Abstract: 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.
