虎皮小牛肝菌的化学成分研究

摘要

Nine compounds were separated and purified from the CHQ3/CH3OH (1:1 ,v/v) extract of Boletinus pictus by silica gel,Rp-18,Sephadex LH-20 column chromatography,respectively. Their structures were identified as methyl li-noleata (1) ,oleic acid (2) ,(22E,24R)-ergosta-5,7,22-trien-3β-ol (3) ,(22E,24R)-ergosta4,6,8(14) ,22-tetraen-3-one (4),trihydroxyergosta-7,22-dien-3β,5α,6β,9α-tetraol (5),dibutyl phthalate (6) ,diisobutyl phthalate (7) , nicotinamide (8) ,and undine (9) on the basis of physicochemical properties and spectroscopic analysis. All compounds are isolated from this fungus for the first time.%采用硅胶、RP-18、Sephadex LH-20等多种材料进行分离纯化,通过理化方法和波谱分析进行结构鉴定,从虎皮小牛肝菌(Boletinus pictus)子实体的氯仿/甲醇(1:1,v/v)提取部位中分离并鉴定了9个化合物,它们分别为:亚油酸甲酯(1)、9(Z)-十八烷烯酸(2)、麦角甾-5,7,22-三烯-3β-醇(3)、麦角甾-4,6,8(14),22-四烯-3-酮(4)、麦角甾-7,22-二烯-3β,5α,6β,9α-四醇(5)、邻苯二甲酸二丁酯(6)、邻苯二甲酸二异丁酯(7)、烟酰胺(8)和尿嘧啶核苷(9).所有化合物均是首次从虎皮小牛肝菌中得到.
