Abstract:

Ferulic methionine ethyl ester (Ⅰ), feruli isoleucine ethyl ester (Ⅱ), feruli threonine ethyl ester (Ⅲ) and feruli phenylalanine ethyl ester (Ⅳ) were synthesized by EDC condensation using ferulic acid and amino acid ethyl ester hydrochloride as raw materials, and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC·HCl) and 1-hydroxybenzotriazole (HOBt) as catalysts. The structure of the products was characterized by 1H NMR and HPLC-MS, and the activities of ferulic acid and ethyl ferulic acid in scavenging DPPH and ABTS free radicals were compared. The results show that the four kinds of ferulic acid ethyl ester scavenged free radicals better, and the scavenging rates are higher than that of ferulic acid monomer. The ferryl phenylalanine ethyl ester (Ⅳ) has the strongest ability to scavenge DPPH free radicals and ABTS free radicals, with IC50 of 37.567 and 1.689 μmol/L, respectively. The red blood cells hemolysis test show that the irritation of the synthesized derivatives of ferulic acid Ⅰ, Ⅲ and Ⅳ is less than that of ferulic acid.

Key words: ferulic acid, ferulic acid ester derivative, DPPH radical, ABTS radical, additives of cosmetics
