Abstract

In this study, an analytical method has been developed for the determination of phenolic compounds since they are related with disease and pests plant resistance mechanisms. The components of the hydrolysed extract (gallic acid, ellagic acid, catechin, epicatechin, caffeic acid, p-coumaric acid and ferulic acid) have been resolved and identified by DAD-HPLC based on their retention times and spectral data. For quantifications, the external standard method was used.
