摘 要 ：对采自云南丽江老君山的顶杯衣(Acroscyphus sphaerophoroides Lév.)的化学成分进行了研究,从中分离得到9个化合物,利用谱学分析方法与文献对照,确定了它们的化学结构。分别鉴定为:甲基茶渍酸(methyl lecanorate,Ⅰ)、茶渍酸(lecanoric acid,Ⅱ)、三苔色酸(gyrophoric acid,Ⅲ)、地衣酚(orcinol,Ⅳ)、苔色酸甲酯(Methyl orsellinate,Ⅴ)、天精(skyrin,Ⅵ)、内赤藓醇(meso-erythritol,Ⅶ)、伏勒米醇(volemitol,Ⅷ)及棕榈酸(palmit-ic acid,Ⅸ)。其中化合物Ⅰ、Ⅱ、Ⅳ、Ⅴ为首次从顶杯衣中分离得到。化合物Ⅲ和Ⅵ是顶杯衣的主要特征性成分。

Abstract:Nine compounds,methyl lecanorate(Ⅰ),lecanoric acid(Ⅱ),gyrophoric acid(Ⅲ),orcinol(Ⅳ),methyl orsellinate(Ⅴ),skyrin(Ⅵ),meso-erythritol(Ⅶ),volemitol(Ⅷ),and palmitic acid(Ⅸ) were isolated from Acroscyphus sphaerophoroides Lév.collected from Laojunshan Lijiang in Yunnan province.Their structures were identified by spectroscopic analysis and comparison with the data reported in literature.Compounds Ⅰ,Ⅱ,Ⅳ and Ⅴ were isolated from Acroscyphus sphaerophoroides Lév.for the first time.Compounds Ⅲ and Ⅵ were the main characteristic components of Acroscyphus sphaerophoroides Lév.
