| Research Abstract |
For the purpose of elucidation of the mechanism for biodegradation of condensed tannin by basidiomycete, isotopic-labelled model compounds were degraded by shiitake (Lentinnus edodes Is). The degradation products were analyzed with GPC and GC-MS. The initial reaction pathway was proposed, that is, the interflavan linkage and C-ring were cleaved to produce catechin, protocatechualdehyde and phloroglucinol.
