Abstract

A series of epicatechin derivatives, including 3-O-palmitoyl epicatechin, 3-O-myristoyl epicatechin, 3-O-lauroyl epicatechin, 3-O-decanoyl epicatechin and 3-O-octanoyl epicatechin, were prepared by the acylation method. Structures of these prepared products were characterized by LC/MS and1H-NMR spectroscopy. Their antioxidant activity were assessed by the methods of DPPH and ABTS free radical scavenging. The results showed that aliphatic acyl epicatechin derivatives with varying aliphatic groups were synthesized by this method. The antioxidant activity of aliphatic acyl epicatechin derivatives were better than the oil-soluble tea polyphenol and BHT, equal to TBHQ.
