Characterization of phenolic compounds in olive stones of three moroccan varieties

Phenolic compounds have a fundamental importance in the nutritional and sensorial characteristics of olive. In this study phenolic compounds extracted from olive fruit stones of three Moroccan registered cultivars were analyzed. The obtained results showed that the total amount of phenolic compounds...

The obtained results showed that the total amount of phenolic compounds varied according to the olive variety. The stones of the Moroccan Picholine variety were the richest in total phenolic compounds (11,32 mg of gallic acid equivalent (GAE)/g of dry weight (DW)) followed by Haouzia (4,55 mg GAE/g DW) and Menara (3,56 mg GAE/g DW).
