摘　　要：紫萁贯众为紫萁科(Osmundaceae)紫萁属植物紫萁(Osmunda japonica Thunb.)带叶柄残基的根茎。本文采用溶剂法及各种色谱方法从紫萁贯众乙酸乙酯部位分离得到6个化合物,通过理化性质和波谱数据分析,分别鉴定为1,7,9,11-四羟基-3-甲基-5,6-二氢-萘骈蒽醌(1),(E)-3,4-二羟基苯亚甲基丙酮(2),原儿茶酸(3),β-谷甾醇(4),β-胡萝卜苷(5)和二十六烷酸(6)。化合物1为首次从植物界中得到,化合物2、3和6均为首次从紫萁属植物中分离得到。Osmundae Rhizoma（Ziqiguanzhong） is the rhizome of Osmunda japonica（Osmundaceae）.Six compounds were isolated from the ethyl acetate extract of Osmundae rhizoma by column chromatography.Their structures were elucidated on the basis of spectral analysis and identified as 1,7,9,11-tetrahydroxy-3-methyl-5,6-dihydrobenzo[a]tetracene-8,13-dione（1）,（E）-3,4-Dihydroxybenzalacetone（2）,protocatechuic acid（3）,β-sitosterol（4）,β-daucosterol（5）,and hexacosoic acid（6）.Compound 1 was isolated from plantae for the first time.
