FREE AND GLYCOSIDICALLY BOUND VOLATILE COMPOUNDS IN FRESH CELERY (APIUM-GRAVEOLENS L)

The volatiles of celery (Apium graveolens L.) were separated into glycosidically bound and free fractions by Amberlite XAD-2 column chromatography combined with direct solvent extraction. The most abundant volatiles were phthalides and psoralens. These are the major volatile compounds found in both the glycosidically bound and free fractions. A total of 34 compounds was identified, including 6 alcohols, 9 terpene and sesquiterpene hydrocarbons, 2 ketones, 7 phthalides, and 5 psoralens. Ten of these have not been previously reported. © 1990, American Chemical Society. All rights reserved.
