粉条儿菜化学成分的研究

Chemical constituents from Aletris spicata

摘要: 采用多种柱色谱方法对百合科粉条儿菜属植物粉条儿菜Aletris spicata(Thunb.)Franch.进行分离纯化，运用波谱学方法鉴定了10个化合物，分别为环石仙桃萜醇(cyclopholidonol， 1 )、白桦脂酸(betulinic acid， 2 )、熊果酸(ursolic acid， 3 )、13-表柏油酸(13-epicupressic acid， 4 )、5-羟基-3，7，4′-三甲氧基黄酮(5-hydroxy-3，7，4′-trimethoxyflavone， 5 )、二十二烷酸-1-甘油酯(2，3-dihydroxypropyl docosoate， 6 )、正十七烷醇(1-heptadecanol， 7 )、正二十四烷酸(lignoceric acid， 8 )、24，24-二甲基-环木菠萝烷-3-醇(cycloneolitsoln， 9 )和β-谷甾醇(β-sitosterol， 10 )。化合物 1~8 均为首次从该属植物中分离得到。

Abstract: Ten compounds were isolated and purified from the ethanol extract of Aletris spicata by various chromatographic methods. Their structures were identified as cyclopholidonol( 1 ), betulinic acid( 2 ), ursolic acid( 3 ), 13-epicupressic acid( 4 ), 5-hydroxy-3, 7, 4′-trimethoxyflavone( 5 ), 2, 3-dihydroxypropyl docosoate( 6 ), 1-heptadecanol( 7 ), lignoceric acid( 8 ), cycloneolitsol( 9 )and β-sitosterol( 10 ). Compounds 1-8 were isolated from genus Aletris for the first time.
