Abstract

First fatty acid divinyl ethers colneleic and colnelenic acids were detected by Galliard et al.1, 2 in in vitro experiments with potato tubers. Formation of these oxylipins, is controlled by 9-lipoxygenase activity and an enzyme, controlling dehydration of 9-hydroperoxide. Such a pathway, being not found in any other plant or animal species, was considered to be the unique property of potato tubers. Our recent in vitro studies of lipoxygenase pathway in garlic bulbs led to detection of novel divinyl ethers 12-[1′(E)-hexenyloxy]-9(Z),11(E)-dodecadienoic (etheroleic) and 12-[1′(E),3′(Z)-hexadienyloxy]-9(Z),11(E)-dodecadienoic (etherolenic) acids3, products of 13-hydroperoxides of linoleic and linolenic acids (13-HPOD and 13-HPOT) conversion, respectively.
