Description	Biocatalytic preparation of acylated derivatives of silybin using several acyl donors (free fatty acids or their esters), catalyzed by immobilized Candida antarctica lipase B, was performed in various organic solvents as well as in imidazolium-based ionic liquids containing either BF-4 or PF-6 anions. Total conversion of silybin was achieved in acetone using short-chain acyl donors (vinyl butanoate) at a 10:1 molar ratio of acyl donor to silybin. The enzymatic process in ionic liquids depended strongly on the alkyl chain length of the cation as well the anion used. Higher conversion yields (up to 75.8 percent) and reaction rates (up to 0.31 mmol h-1 g-1 biocatalyst) were obtained in the BF-4 as compared with PF-6 - containing ionic liquids Biocatalytic preparation of acylated derivatives of silybin using several acyl donors (free fatty acids or their esters), catalyzed by immobilized Candida antarctica lipase B, was performed in various organic solvents as well as in imidazolium-based ionic liquids containing either BF-4 or PF-6 anions.
