The main compounds identified were fatty acids, ketones, alcohols, aldehydes and monoterpene groups.
Nevertheless, there are reports confirming the antimycotic activity of the main compounds identified by GC-MS in the present volatile fractions.
In addition, ω-hydroxyacids and α,ω-diacids with mid-chain substituents, such as an unsaturation, an epoxy, or a vic-diol group (peaks 15, 16, 20, 23, 27, 28, 29 and 30 ) are among the main compounds identified.

Data, presented in Table 2 demonstrate that the main compounds identified in all extracts were caffeic, trans-p-coumaric, ferulic acids.
The main compounds identified in the other active oils were b-pinene, E-pinocamphone, E-caryophyllene, E-pinocarveol acetate and guaiol in A. gratissima and, a-pinene, a-bulnesene, E-pinocarveol and a-copaene in C. articulatus.
According to other data reported by Zoubiri et al.[36] we have supposed that this effect was due to linalool - the main compound identified in O3.
The main compound identified in the EOMiE was terpinolene (73.6 ± 0.2%), with δ-3-carene (5.7 ± 0.0%) being the second most abundant.
Monoterpenes are the main chemical compounds identified in O3.
The main phenolic compounds identified through HPLC MS in fermented apricot press residues were chlorogenic acid, neochlorogenic acid, rutin, and quercetin 3-acetyl glucoside.
Gallic acid, syringic acid, procyanidins B1 and B2, catechin, epicatechin, epicatechin gallate, quercetin 3-β-d-glucoside, delfinidin 3-glucoside, peonidin 3-O-glucoside, and malvidin 3-glucoside were the main phenolic compounds identified.
