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 study the chemical constituents of Pluchea indica roots. Methods: The compounds were isolated and purified by various column chromatographic methods, and their structures were identified according to the physicochemical properties and spectral data. Results: Twelve compounds were isolated and identified as squalene, 1-hydroxy-2,3,4,5-trihydroxy- 5-tetramethoxyxanthone, syringaresino, caffeic acid, phloroglucinol, 3,5-dihydroxy-benzoic acid, protocatechuic aldehyde protocatechuicaldehyde, 5-hydroxy vanillin, gallic acid, syringate, 5a, 8a-peroxyetigaster- (3,5,8,22E) -6, 22-dien-3β-ol [5α, 8α-epidioxy- (3,5,8,22E) -ergosta-6,22-dien-3-ol], adenosine. CONCLUSION: The above compounds were isolated from this plant for the first time, and the small molecule phenolic acids may have certain chemical and ecological significance.
