 Title    Degradation of the Isoflavone Biochanin A by Fusarium javanicum  
 Abstract    After a lag-phase of 1 h a mycelial suspension of Fusarium javanicum completely degraded 5,7-dihydroxy-4'-methoxyisoflavone (biochanin A) to a series o f transiently accumulating catabolites. The compounds were elucidated by spectroscopic techniques and are arranged in the first known degradative pathway for an isoflavone: biochanin A -* dihydrobiochanin A -* 3-(/?-methoxyphenyl)-4,6-diketo-5,6-dihydro-4H-pyran -* />-methoxyphenylacetic acid -*■ p-hy-droxyphenylacetic acid -*■ 3,4-dihydroxyphenylacetic acid -*■ C 0 2. The carbon atoms o f bio­ chanin A not accounted for by this sequence are discussed in relation to microbial flavonoid pathways.
