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。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.
