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 3是首次从该植物分得 Four lignans were obtained from the seeds of the medicinal plant Eagle claws: iso-americanin A (1), iso-americanol A (2), and B (americanin B, 3). Artabotrycinol (4) and one and a half quinones: (R) eagle paw triol [(R) artabotriol, 5 ], and palmitic acid (6 ), β sitosterol (7) and carotenoid (8) . According to spectral data (IR, UV, MS, 1D, 2D NMR) analysis, determine their chemical structure. Among them, eaglewood lignan (4) is a neo-lignan, (R) eagle pawtriol (5) is a neo-semisterol. The lignan compounds 1, 2 and 3 were first obtained from this plant
