喜光花叶的化学成分研究(I)

Chemical constituents in leaves of Actephila merrilliana (I)

目的研究喜光花Actephila merrilliana叶中的化学成分。方法采用各种柱色谱方法进行分离,通过理化方法和波谱数据进行结构鉴定。结果分离得到13个化合物,分别鉴定为2-甲氧基呫吨酮(2-methoxy-9H-xanthen-9-one,1)、2-羟基呫吨酮(2-hydroxy-9H-xanthen-9-one,2)、喹啉(quinoline,3)、香草醛(3-methoxy-4-hydroxy-benzaldehyde,4)、邻苯二甲酸正辛酯(di-n-octyl phthalate,5)、邻苯二甲酸-二(2-乙基-己基)酯[bis(2-ethylhexyl)phthalate,6]、β-萘酚(β-naphthol,7)、丁香醛(3,5-dimethoxy-4-hydroxy-benzaldehyde,8)、羽扇豆醇(lupeol,9)、鹅掌楸碱(liriodenine,10)、异吴茱萸脑(isoevodionol,11)、腺嘌呤(adenine,12)、丁二酸(succinic acid,13)。结论以上所有化合物均为首次从该属植物中分离得到。
