Phaeolschidin F (1) was isolated from fruiting bodies of the bitter and toxic mushroom Gymnopilus aeruginosus. Structure analysis by NMR and MS revealed that 1 is a new symmetrical bis(styrylpyrone). A series of anti-oxidant and pro-oxidant tests characterized that 1 is a redox catalyst having more anti-oxidant and less pro-oxidant activities than quercetin.
从有毒苦味蘑菇铜绿裸伞的子实体中分离得到了褐黄菌素F(1)。通过核磁共振(NMR)和质谱(MS)进行的结构分析表明,1是一种新型对称双(苯乙烯基吡喃酮)。一系列抗氧化和促氧化测试表明,1是一种氧化还原催化剂,其抗氧化活性比槲皮素高,促氧化活性比槲皮素低。
