对叶百部中的非生物碱类成分

Non-alkaloid Constituents from the Root of Stemona tuberosa

从百部科植物对叶百部中分离鉴定了11个化合物,分别为大黄素甲醚(1),3-羟基-4-甲氧基苯甲酸(2),对羟基苯甲酸(3),(Z)-1,1′-biindenyliden(4),胸腺嘧啶(5),2-(1′,2′,3′,4′-四羟基丁基)-6-(2′′,3′′,4′′-三羟基丁基)-吡嗪(6),掌叶半夏碱戊(7),豆甾醇(8),β-谷甾醇棕榈酸酯(9),β-谷甾醇(10)和β-胡萝卜苷(11)。其中化合物1～9均为首次从该科植物中分得。

Eleven compounds were isolated from the root of Stemona tuberosa,and their structures were elucidated as physcioin（1）,3-hydroxy-4-methoxybenzoic acid（2）,p-hydroxybenzoic acid（3）,（Z）-1,1＇-biindenyliden（4）,thymine（5）,2-（1′,2′,3′,4′-tetrahydroxybutyl）-6-（2′′,3′′,4′′-trihydroxybutyl）-pyrazine（6）,2-methyl-5-（1′,2′,3′,4′-tetrahydroxybutyl）-pyrazine（7）,stigmasterol（8）,β-sitosterol palmitate（9）,β-sitosterol（10） and β-daucosterin（11）.Compounds 1~9 were isolated from Stemonaceae for the first time.
