Abstract

A detailed study of the biotransformation of 6- and 7-methoxyflavones by four fungal strains (Aspergillus niger strains MB, KB, and SBP; Penicillium chermesinum 113) was carried out. Products of demethylation and also demethylation combined with hydroxylation at C-4' were identified. The biotransformation products were stronger antioxidants than the substrates.

摘要

对 6- 和 7-甲氧基黄酮在四种真菌菌株（黑曲霉 MB、KB 和 SBP；产黄青霉 113）中的生物转化进行了详细研究。鉴定出了脱甲基产物，以及 C-4'位脱甲基与羟化相结合的产物。生物转化产物的抗氧化能力强于底物。
