Microbial transformation of diosgenin (3β-hydroxy-5-spirostene) using white-rot fungus Coriolus versicolor afforded four previously unreported polyhydroxylated steroids, 25(R)-spirost-5-en-3β,7α,15α,21-tetraol (5), 25(R)-spirost-5-en-3β,7β,12β,21-tetrol (6), (25R)-spirost-5-en-3β,7α,12β,21-tetraol (7), and (25R)-spirost-5-en-3β,7β,11α,21-tetraol (8), along with three known congeners, 25(R)-spirost-5-en-3β
使用白腐菌薯蓣皂苷元(3β-羟基-5- spirostene)的微生物转化云芝得到4以前未报告的多羟基化的类固醇,25([R)-spirost -5-烯-3β,7α,15α,21-四醇(5) ,25(R)-spirost-5-en-3β,7β,12β,21-四醇(6),(25 R)-spirost-5-en-3β,7α,12β,21-四醇(7)和(25 R)-spirost-5-en-3β,7β,11α,21-tetraol(8)以及三个已知的同类物25(R -spirost-5-en-3β,7β-diol(2), 25(R)-spirost-5--5-en-3β,7β,21-triol(3)和25(R)-spirost-5-en-3β,7β,12β-三醇(4)。通过1D和2D NMR以及HR-ESIMS分析阐明了这些结构。此外,我们提供了薯di皂素的两个新微生物羟基化的证据:C-21初级
