Synthesis of hydroxytyrosyl alkyl ethers from olive oil waste waters

Molecules. 2009 May 11;14(5):1762-72. doi: 10.3390/molecules14051762.

Abstract

The preparation of a new type of derivatives of the naturally occurring antioxidant hydroxytyrosol is reported. Hydroxytyrosyl alkyl ethers were obtained in high yield by a three-step procedure starting from hydroxytyrosol isolated from olive oil waste waters. Preliminary results obtained by the Rancimat method have shown that these derivatives retain the high protective capacity of free hydroxytyrosol.
