Feruloylated monoacyl- and diacyl-glycerols (FMAGs and FDAGs) are lipophilic antioxidants and potential UV absorbers. FMAGs and FDAGs were synthesized by a novel chemoenzymatic method: firstly, ferulic acid was esterified with glycerol to synthesize glyceryl ferulate, using p-toluenesulfonic acid as chemical catalyst in 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF(4)); secondly, glyceryl ferulate was esterified with oleic acid to synthesize FMAGs and FDAGs, using Novozym 435 as biocatalyst in 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim]PF(6)). The conversion of ferulic acid and yield of glyceryl ferulate in the first reaction were both 98%. The yields of FMAGs and FDAGs in the second reaction reached 34 +/- 2% and 66 +/- 3%, respectively.
