 "The origin of the species is disputed. It was known in Armenia during ancient times, and has been cultivated there for so long, it is often thought to have originated there." [[http://en.wikipedia.org/wiki/Prunus_armeniaca]]

+"The combination of 2-aminobenzaldehyde and 2-aminoacetophenone, sometimes accompanied by methyl anthranilate, can be regarded as a scent concept important to nature and frequently found in nature, e.g. In Prunus species." \\
+The headspace of Prunus armeniaca flower contained 2-aminobenzaldehyde (1.1%; orange-flower like) and 2-aminoacetophenone (0.8%; grape, sweet green). \\

-(R)-(+)-γ-decalactone was the predominant enantiomer (94-100%) in the headspace aroma of 14 apricot fruit cultivars, but (R)-(+)-γ-dodecalactone (although enantiomerically pure) was detected in only five cultivars.
+Major volatile components of dried (sun, hot air, microwaves) aricots were 5-hydroxymethylfurfural (5-HMF), 2,3-dihydro-4-H-pyran-4-one and furfural. When apricots were dried using only a desiccator, limonene (16.3%), (E)-2-hexenal (9.3%), γ-decalactone (7.8%), butyl acetate (6.9%), β-ionone (5.9%), acetic acid (4.8%) and isobutanal were found to be the major components. \\
-Enantiomeric composition of γ-decalactone and γ-dodecalactone did not change during ripening. \\
