隐孔菌子实体化学成分的研究

Studies on Chemical Constituents from Fruiting Bodies of Cryptoporus volvatus

目的:对隐孔菌Cryptoporus volvatus子实体的化学成分进行研究。方法:利用不同的色谱分离纯化手段分离单体化合物,根据化合物的理化常数和谱学数据进行结构鉴定。结果:从隐孔菌子实体的90%乙醇水提取物中分离得到了13个化合物,分别鉴定为1',2'-二羧基隐孔酸B(1)、豆甾醇(2)、豆甾-7-烯-3β-醇(3)、邻苯二甲酸二丁酯(4)、腺苷(5)、鸟苷(6)、尿苷(7)、尿嘧啶(8)、1-核糖醇基-2,3-二酮-1,2,3,4-四氢-6,7-二甲基-喹喔啉(9)、D-阿拉伯糖醇(10)、D-半乳糖醇(11)、D-山梨糖醇(12)、二十四烷酸(13)。结论:除化合物1外,其余化合物均为首次从该属真菌中分离得到。

Objective ： To study the chemical constituents of the fruiting bodies of Cryptoporus volvatus. Methods ： I- solation and purification of the compounds were carried out by various chromatographies, and their structures were identified according to the physical and chemical properties as well as spectroscopic methods. Results： Thirteen compounds were obtained and identified as 1＇, 2＇-dicarboxylic cryptoporic acid B （ 1 ）, stigmasterol （2）, stigmast-7-en-3β-ol （3）, dibutyl phthalate （4）, adenosine（5）, guanosine（6）, uridine（7）, uracil（8）, 1-ribityl-2, 3-diketo-1, 2, 3, 4-tetrahydro-6, 7-dimethyl-quinox- aline （9）, D-arabitol （ 10 ）, D-galactitol （ 11 ）, D-sorbitol （ 12 ）, tetracosanoic acid （ 13 ）, respectively. Conclusion： Except compound 1, all compounds were isolated from genus Cryptoporus for the first time.
