The present invention relates to the method for obtaining in pure form or as a mixture of the bioactive diol forms of the main secoiridoid phenols present in olive oil and certain isomeric forms or derivatives thereof. Specifically, it relates to the production process of S-(E)- oleocanthadiol, S-(E)-oleaceinediol, 5S-(E)-oleomissionadiol, 5S-(E)-oleokoronadiol, oleuropeinediol and ligstrodiol and their corresponding polyethylene glycol hemiacetals through extraction of specifically selected olive oil with polyethylene glycol and then treated with water. It also relates to the pharmaceutical preparations containing the above substances in various combinations and the therapeutic properties of these preparations for the treatment of cancer, degenerative diseases of the central nervous system, diabetes, hyperlipidemia, inflammatory diseases and the prevention of creation of atherosclerotic plaques and thrombi. |
