METHOD FOR PREPARING ORTHODIHYDROXYISOFLAVONES USING A BIOTRANSFORMATION SYSTEM

摘要

Disclosed herein is a method for preparing ortho-dihydroxyisoflavones using a biotransformation system. More specifically, disclosed is a method for preparing ortho-dihydroxyisoflavones, which comprises biotransforming daidzein or genistein by actinomycete microorganisms, particularly Streptomyces avermitilis, Nocardia farcinica or Streptomyces lincolnesis, in order to efficiently prepare ortho-dihydroxyisoflavones having an excellent antioxidant function and a whitening effect.
