目的:研究忽地笑生物碱部位的化学成分。方法:采用各种色谱方法对生物碱部位进行分离,利用NMR、MS等波谱手段对所分离的生物碱成分进行结构鉴定。结果:分离得到12个生物碱:O-甲基石蒜伦碱(1)、石蒜伦碱(2)、O-乙基石蒜伦碱(3)、力克拉敏(4)、石蒜碱(5)、加兰他敏(6)、O-去甲基力克拉敏(7)、N-去甲基力克拉敏(8)、伪石蒜碱(9)、漳州水仙碱(10)、O-去甲加兰他敏(11)、N-去甲基加兰他敏(12)。结论:化合物3、8为首次从该植物中分离得到。
OBJECTIVE: To study the chemical composition of the alkaloid site of laughter and laughter. Methods: The alkaloids were separated by various chromatographic methods. The structures of the isolated alkaloids were identified by NMR, MS and other spectroscopic methods. RESULTS: Twelve alkaloids were isolated and purified from the leaves of mice. O-methyllithium (1), Lycoris (2), O-ethyllizone (3) (5), galantamine (6), O-desmethyl Lactamene (7), N-desmethyl Lactamene (8), Luteolin (9) , O-nor-plus galantamine (11), N-demethyl-galantamine (12). Conclusion: Compounds 3 and 8 were isolated from this plant for the first time.
