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, Sneakers for Men - Grey - Canvas Mesh Athletic Running Shoes 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 chromatography).The structures of the bostik universal primer pro products were confirmed with spectroscopic methods (NMR: 1H, 13C, HSQC, HMBC, COSY).The compounds obtained by us expand the library of available flavonoid derivatives and can be used in biological research.
