中文摘要：

从椭圆嗜蓝孢孔菌Fomitiporia ellipsoidea子实体的石油醚提取物中分离得到6个化合物,分别是麦角甾-7,22,25-三烯-3-酮,21-羟基羊毛甾-7,9（11）,24-三烯-3-酮,麦角甾-7,22-二烯-3β-棕榈酸酯,麦角甾-7,22-二烯-3-酮,麦角甾醇和过氧化麦角甾醇;从其脱脂后的氯仿提取中分离得到了3个化合物,分别是：苯并（1,2-b;5,4-b′）二呋喃-3,5-二酮-8-甲酸甲酯,麦角甾-7,22-烯-3β-醇和β-谷甾醇。其中苯并（1,2-b;5,4-b′）二呋喃-3,5-二酮-8-甲酸甲酯和麦角甾-7,22,25-三烯-3-酮为新化合物,其余化合物为首次从椭圆嗜蓝孢孔菌中分离得到。

英文摘要：

Six compounds were isolated from petroleum ether extract of Fomitiporia ellipsoidea fruiting bodies.They are ergosta-7,22,25-triene-3-one,21-hydroxylanosta-7,9（11）,24-trien-3-one,ergosta-7,22-dien-3β-ylpalmitate,ergosta-7,22-dien-3-one,ergosterol,and ergosterol peroxide.Three compounds,benzo[1,2-b：5,4-b＇]difuran-3,5-dione-8-methyl formate,ergosta-7,22-dien-3- ol and β-sitosterol,were isolated from defatted chloroform extract.Ergosrta-7,22,25-triene-3-one and benzo[1,2-b：5,4-b＇]difuran- 3,5-dione-8-methyl formate are two new compounds;the others are isolated from Fomitiporia ellipsoidea fruiting bodies for the first time.
