Glycosidically bound fraction was separated from apricot by Amberlite XAD-2 adsorption and eluted with methanol. Aglycones were liberated from the bound fraction by enzymatic hydrolysis, acid hydrolysis or by means of simultaneous distillation-extraction at pH 3.0. A total of 40 components were identified in three bound volatile fractions. Besides linalool oxide, linalool. ${\alpha}-terpineol$, nerol, geraniol, benzyl alcohol and 2-phenylethyl alcohol, previously reported as glycosidically bound volatiles, the following components were identified for the first time as glycosidically bound volatiles in apricot: 2,6-dimethyl-3,7-octadiene-2,6-diol , 3.7-dimethyl-1,5-octadiene-3,7-diol, (E)- and (Z)-2.6-dimethyl-2,7-octadiene-1,6-diol, $3,4-didehydro-{\beta}-ionol,\;3-oxo-{\alpha}-ionol$, $3-hydroxy-7,8-dihydro-{\beta}-ionol,\;3-oxo-7,8-dihydro-{\alpha}-ionol ,\;3-hydroxy-{\beta}-ionone$, eugenol, 4-hydroxyethylphenyl acetate and 2,3-dihydrobenzofuran.
