标题 :Enzymatic synthesis of phenolic acid esters and steryl phenolates
发明人：NYSTRÖM LAURA; SCHÄR ALINE
权利人:ETH ZUERICH
摘要:The present invention relates to a method for obtaining at least one steryl phenolate from at least one phenolic acid in an enzymatic process using a lipase, wherein in a first step a) the at least one phenolic acid and at least one alcohol R 1 -OH undergo an enzymatic esterification to at least one phenolic acid ester according to reaction scheme (III)n n, and in at least one second step b) the at least one phenolic acid ester and at least one sterol R 2 -OH undergo an enzymatic transesterification using a lipase to at least one steryl phenolate according to reaction scheme (IV)
