 The lactones of apricot like γ-hexalactone (10-245 ppb), γ-decalactone (300-610 ppb), γ-dodecalactone (40-75 ppb), δ-decalactone (85-115 ppb), are preferentially (R)-configured (80-98% ee) with the exception of (Z)-7-decen-5-olide (jasminlactone; 50-160 ppb; S 94-95%ee). \\ The lactones of apricot like γ-hexalactone (10-245 ppb), γ-decalactone (300-610 ppb), γ-dodecalactone (40-75 ppb), δ-decalactone (85-115 ppb), are preferentially (R)-configured (80-98% ee) with the exception of (Z)-7-decen-5-olide (jasminlactone; 50-160 ppb; S 94-95%ee). \\

 +"The aroma volatiles of the apricot distillate were characterized by a high concentration of alcohols and by a specific terpene profile that included linalool, ocimenol, α-terpineol, nerol, geraniol, cis and trans linalol oxide. γ-Decalactone, γ-dodecalactone, and ethyl cinnamate were also characteristic of the apricot distillate. The apple distillate exhibited a high concentration of esters and was characterized by the presence of farnesol, cis and trans α-farnesene, ethyl hexanoate, ethyl 9-decenoate, ethyl 3-methylbutanoate, guaiacol and (Z) 3-hexen-1-ol. In the case of apricot distillate, olfactometric analysis showed that volatile compounds, such as β-damascenone, ethyl 2-methylbutanoate, linalool, methyl anthranilate, ethyl cinnamate, γ-decalactone and γ-dodecalactone, which probably resulted from the original fruit, had a significant odor activity, while 2-phenylethanol was the main odor impact compound. The aroma profile of the apple distillate was mainly characterized by 2-phenylethanol, β-damascenone and ethyl 3- and ethyl 2-methylbutanoate." \\

 "Finally, 10 compounds, ethyl acetate, hexyl acetate, limonene, β-cyclocitral, γ-decalactone, 6-methyl-5-hepten-2-one, linalool, β-ionone, menthone and (E)-hexen-2-al were recognized by HS-SPME-GC-O as responsible of the aromatic notes involved in apricot aroma and considered as molecular tracers of apricot aromatic quality which could be utilized to discriminate apricot varieties." \\ "Finally, 10 compounds, ethyl acetate, hexyl acetate, limonene, β-cyclocitral, γ-decalactone, 6-methyl-5-hepten-2-one, linalool, β-ionone, menthone and (E)-hexen-2-al were recognized by HS-SPME-GC-O as responsible of the aromatic notes involved in apricot aroma and considered as molecular tracers of apricot aromatic quality which could be utilized to discriminate apricot varieties." \\
