Abstract

Abstract: Lipase has been employed as a green catalyst to esterify 7-and 6-hydroxy-4- methyl-coumarin with different fatty and acetic acid. The esterified coumarins have been evaluated for antioxidant activities using DPPH and ABTS assays, among them 3a and 5a are known as active antioxidants.
