Abstract: Eight compounds,contigoside A(1),contigoside B(2),onychin (3),trans-cinnamic acid(4),wallichoside (5),β-sitosterol (6),daucosterol (7),and sucorse (8) were isolated from the methanolic extract of the aerial parts of Onychium contiggum.Compound 1 and 2 were new ones. Trans -cinnamic acid (4) was isolated from Onychium for the first time. Their structures were assigned by a combination of one and two dimensional NMR techniques.

Key words: Onychium contiggum, Sinopteridaceae, Flavone and flavone glycoside

摘要： 从高山金粉蕨(Onychium contigqum)地上部分的甲醇抽提物中分到8个成分：高山金粉蕨甲甙(l)，高山金粉蕨乙甙(2)，金粉蕨素(3)，反式桂皮酸(4)，瓦利甙(5)，β-谷甾醇(6)，胡萝卜甙(7)和蔗糖(8)。高山金粉蕨甲甙和乙甙是新成分，反式桂皮酸系首次从金粉蕨属中分到。化学结构用一维和二维核磁共振技术确定。
