摘 要:目的:研究阔苞菊Pluchea indica根的化学成分。方法:利用各种柱色谱方法进行分离纯化,根据理化性质和波谱数据鉴定其结构。结果:分离得到12个化合物,分别鉴定为:角鲨烯(squalene)、1-羟基-2,3,4,5-甲氧基(口山)酮(1-hydroxy-2,3,4,5-tetramethoxyxanthone)、丁香脂素(syringaresino)、咖啡酸(caffeicacid)、间苯三酚(phloroglucinol)、3,5-二羟基苯甲酸(3,5-dihydroxy-benzoic acid)、原儿茶醛(protocatechuicaldehyde)、5-羟基香兰醛(5-hydroxy vanillin)、没食子酸(gallic acid)、丁香酸(syringate)、5α,8α-过氧麦角甾-(3,5,8,22E)-6,22-二烯-3β-醇[5α,8α-epidioxy-(3,5,8,22E)-ergosta-6,22-dien-3-ol]、腺苷(adenosine)。结论:以上化合物均为首次从该植物中分离得到,且其中的小分子酚酸类成分可能具有一定化学生态学意义。Objective: To investigate the chemical constituents from roots of Pluchea indica. Methods: Chromatographic methods were applied to isolate pure compounds and their structures were elucidated by spectroscopic data. Results: Twelve compounds were isolated and their structures were identified as squalene ( 1 ), 1-hydroxy-2,3 ,g ,5-tetramethoxyxanthone (2), syringaresino (3), caffeic acid (4), phloroglueinol (5), 3,5-dihydroxy-benzoic acid (6), protocatechuic aldehyde (7), 5-hydroxy vaniUin (8), gallic acid (9), syringate ( 10), 5,8-epidioxy-(3,5,8,22E)-ergosta-6,22-dien-3-ol ( 11 ), adenosine (12). Conclusion: These compounds were isolated from Pluchea indica for the first time and the low molecular weight phenolic acids of them may play ecological role.
