密褶红菇化学成分研究

Chemical study on Russula densifolia

从红菇科密褶红菇 (Russuladensifolia)的子实体中分离得到 15个化合物 ,经波谱分析鉴定为D 阿洛糖醇(1)、硬脂酸 (2 )、3 -羧酸呋喃 (3)、(2 2E ,2 4R) - 3β- hydroxyergosta- 5 ,2 2 - diene(4)、3β- hydroxy- 5α ,8α- epidioxy 2 4 ξ- methylc holesta- 6 - ene(5 )、琥珀酸酐 (6 )、3β- hydroxy -5α ,8α- epidioxyergosta 6 ,2 2 diene(7)、软脂酸 (8)、尿嘧啶 (9)、顺丁烯二酸(10 )、硫代乙酸酐 (11)、1,4 丁二酸 (12 )、1- 乙基 β D 吡喃葡萄糖苷 (13)、2- acetamino 2 - deoxy- β- D -glucose(14 )和cerebrosideB(15 )。

Fifteen compounds were isolated from higher fungus Russula densifolia.They were identified as D-allitol(1),stearic acid(2),furan-3-carboxylic acid(3),(22E,24R)-3β-hydroxyergosta-5,22-diene(4),3β-hydroxy-5α,8α-epidioxy-24ξ-methylcholesta-6-ene(5),dihydrofuran-2,5-dione(6),3β-hydroxy-5α,8α-epidioxyergosta-6,22-diene(7),palmitic acid(8),uracil(9),cis-butenedioic(10),thioacetic anhydride(11),succinic acid(12),1-ethylic-β-D-glycoside(13),2-acetamino -2-deoxy-β-D-glucose(14) and cerebroside B(15).
