Abstract: A new styryl-2-pyrone glucoside (1) and a known styryl-2-pyrone glucoside (2) , together with four other known compounds (3 - 6) , were isolated from the ethanol extract of the fern Brainea insignis . The structures of these compounds were determined by means of spectroscopic analysis including 1D and 2D NMR, HR-MS . And the capacities to scavenge against DPPH radical of two styryl-2-pyrone glucosides were assayed .

Key words: Fern

摘要： 从蕨类植物苏铁蕨( Brainea insignis) 中分离得到1 个新的苯乙烯基吡喃酮苷, 利用波谱技术鉴定了其结构。此外, 还得到了1 个已知的苯乙烯基吡喃酮苷和4 个其它已知化合物。同时, 还测定了分离得到的两个苯乙烯基吡喃酮苷化合物的DPPH 自由基清除活性。

关键词: 蕨类植物, 苏铁蕨, 苯乙烯基吡喃酮苷, DPPH 自由基清除活性
