Glycosylation of Methoxylated Flavonoids in the Cultures of Isaria fumosorosea KCH J2.

ABSTRACT: Flavonoids are widely described plant secondary metabolites with high and diverse pro-health properties. In nature, they occur mostly in the form of glycosides. Our research showed that an excellent way to obtain the sugar derivatives of flavonoids is through biotransformations with the use of entomopathogenic filamentous fungi as biocatalysts. In the current paper, we described the biotransformations of five methoxylated flavonoid compounds (2'-methoxyflavanone, 3'-methoxyflavanone, 4'-methoxyflavanone, 6-methoxyflavanone, and 6-methoxyflavone) in cultures of Isaria fumosorosea KCH J2. As a result, we obtained twelve new flavonoid 4-O-methylglucopyranosides. The products were purified with methods that enabled the reduction of the consumption of organic solvents (preparative TLC and flash
