Isol. from garlic (Allium sativum) extracts. Nutriceutical with anti-cancer props. Ajoene (pronounced /???ho?i?n/) is a chemical compound available from garlic (Allium sativum). The name (and pronunciation) is derived from 'ajo', the Spanish word for garlic. It is found as a mixture of two isomers, E-, and Z- 4,5,9-trithiadodeca-1,6,11-triene 9-oxide.; Ajoene, an unsaturated disulfide, is formed from the bonding of three allicin molecules. Allicin is a sulfinyl compound that gives garlic its strong odor and flavor. The release of allicin occurs after a garlic clove is crushed or finely chopped. Subsequent formation of ajoene occurs when allicin is dissolved in various solvents including edible oils. Ajoene is also found in garlic extract. Ajoene is most stable and most abundant in macerate of garlic (chopped garlic in edible oil).
