【摘要】 采用多种色谱技术,从石蒜鳞茎中分离鉴定了10个生物碱类成分。运用IR,UV,CD,MS,NMR等波谱分析方法鉴定了化合物的结构,分别为oxovittatine(1),apohaemanthamine(2),9-O-demethylhomolycorine N-oxide(3),incartine(4),ismine(5),6-O-methylpretazettine(6),多花水仙碱(7),恩其明(8),高石蒜碱(9)和甲基石蒜伦碱(10)。其中化合物1为新的天然产物,化合物2～3为首次从石蒜属植物中分离得到,化合物4～6为首次从该植物中分离得到。更多还原

【Abstract】 Ten Amaryllidaceae alkaloids were isolated from the bulbs of Lycoris radiata.Their structures were identified as oxovittatine(1),apohaemanthamine(2),9-O-demethylhomolycorine N-oxide(3),incartine(4),ismine(5),6-O-methylpretazettine(6),tazettine(7),ungeremine(8),homolycorine(9),and O-methyllycorenine(10) by spectroscopic data analyses.Compound 1 was a new natural product.Compounds 2 and 3 were reported form the genus Lycoris for the first time and compounds 4-6 were isolated form the title plant for the first time.更多还原
