A novel, two consecutive enzyme synthesis of feruloylated monoacyl- and diacyl-glycerols in a solvent-free system.
Feruloylated mono- and di-acylglycerols were synthesized in a two step reaction: ethyl ferulate was first transesterified with glycerol and then this was esterified with oleic acid. The yield of the combined feruloylated mono- and di-acylglycerols in the second reaction reached 96% when esterification of 0.3 g transesterification products with 2.22 g oleic acid was catalyzed with 0.25 g Candida antarctica lipase at 60 degrees C under a vaccum of 10 mmHg for 1.33 h.
