Antioxidant Activities of Imino Chromene Derivatives with Even Alkyl tail: Synthesis and Characterisation

Abstract

The reaction between substituted 4-hydroxybenzaldehyde, active methylene compounds iminochromene derivatives. Structures of the sewere established upon the basis of IR,1HNMR,13CNMR,and MASS data. Invitro, antioxidants activities oft hese compounds against superoxide anion radical, nitric oxide radical, DPPH radical and hydrogen peroxide were evaluated and compared with standard natural antioxidants ascorbicacid.
