忍冬木层孔菌化学成分研究

Study on the Chemical Constituents of Phellinus lonicerinus

目的:研究忍冬木层孔菌的化学成分。方法:采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱及反相柱色谱进行分离纯化,并运用波谱方法对化合物进行结构鉴定。结果:从忍冬木层孔菌中共分离得到了6个化合物,分别鉴定为:麦角甾醇过氧化物(1)、麦角甾醇(2)、香草醛(3)、3,4-二羟基苄叉丙酮(4)、β-谷甾醇(5)和正二十二烷酸(6)。结论:以上化合物均为首次从忍冬木层孔菌中分离得到,其中,化合物4为新天然产物。

Objective：To study the chemical constituents of Phellinus lonicerinus.Methods：The constituents were seperated and purified by silica column chromatography,Sephadex LH-20 and other column chromatography,then their structures were identified by spectral methods.Results： Six compounds were isolated and identified as ergosta-6,22-dien-3β,5β,8β-triol（1）,erogosterol（2）,vanillin（3）,3,4-dihydroxy benzalacetone（4）,β-sitosterol（5）,docosanoic acid（6）.Conclusion：All compounds are isolated from Phellinus lonicerinus for the first time and compound 4 isa new natural product.
