摘要
目的研究变绿红菇Russula virescens子实体化学成分。方法变绿红菇子实体用95%乙醇浸泡提取浓缩,经硅胶、RP-8、Sephadex LH-20等多种材料进行分离,波谱学方法鉴定化合物的结构。结果分离鉴定了8个化合物,分别为铁屎米酮(canthin-6-one,Ⅰ)、3β-羟基-5α,8α-过氧化麦角甾-6,22-二烯(Ⅱ)、3β-羟基-麦角甾-5,7-22-三烯(Ⅲ)、3β,5α,6β-三羟基-麦角甾-7,22-二烯(Ⅳ)、硫代乙酸酐(Ⅴ)、顺丁烯二酸(Ⅵ)、D-阿洛醇(Ⅶ)、腺嘌呤核苷(Ⅷ)。结论所有化合物均为首次从该菌中分到,其中化合物为首次从该属中分到。
Objective To study the active constituents of Russula virescens. Methods The compounds were isolated by silica gel, RP-8, Sephadex LH-20 and their structures were elucidated by spectral methods. Results Eight compounds were isolated and identified as canthin-6-one （ Ⅰ ）, 5α, 8α-epidioxy-（22E, 24R）-ergosta-6, 22-dien-3β-ol （Ⅱ）, （22E, 24R）-ergosta-5, 7, 22-trien-3β-ol （Ⅲ）, （22E, 24R）-ergosta- 7, 22-dien-3β, 5α, 6β-triol （ Ⅳ ）, thioacetic anhydride （ Ⅴ ）, maleic acid （ Ⅵ ）, D-allitol （Ⅶ）, ribosidoad-enine （Ⅷ）. Conclusion All compounds are isolated from this high fungus for the first time and compound Ⅰ is firstly isolated from plants of genus Russula.
