椭圆嗜蓝层孔菌子实体化学成分研究

摘要

椭圆嗜蓝层孔菌(Phellinus ellipsoidea)子实体甲醇提取物依次用石油醚和乙酸乙酯萃取,其乙酸乙酯分部经柱层析分离得到11个化合物.经鉴定这11个化合物分别为:苯并(1,2-b,5,4-b')二呋喃-3,5-二酮-8-甲酸甲酯(1)、原儿茶酸(2)、4-(3,4-二羟苯基)-3-丁烯-2-酮(3)、原儿茶醛(4)、Hispidin (5)、Hispolon (6)、Inoscavin A(7)、Phelligridin K(8)、Inoscavin C(9)、Inoscavin E(10)和Inonoblins B(11),其中化合物2、4、7、10为首次从该物种中分离得到.%Eleven chemical compounds of Phellinus ellipsoidea fruit bodies were isolated by column chromatography,and their structures elucidated by chemical analyses,mass spectroscopy and NMR.They were identified as fomitiporiaester A(1),protocatechuic acid (2),(E)-4-(3,4-dihydroxyphenyl) but-3-en-2-one(3),protocatechualdehyde(4),hispidin(5),hispolon(6),inoscavin A(7),phelligridin K(8),inoscavin C(9),inoscavin E(10),and inonoblins B(11).Of these,components 2,4,7 and 10 have been isolated from P.ellipsoidea fruit bodies for the first time.
