## 3 Results and Discussion
In the case of pine honey, the compounds methyl butanal (isomer) (C1), cyclopentane, 1,3-dimethyl-(isomer) (C2), heptane (C3), furan, 2,5-dimethyl-(C4), cyclohexane, methyl-(C5), 1-pentanol (C7), methyl isobutyl ketone (C11), disulfide dimethyl (C12), toluene (C16), 1-octene (C20), octane (C21), furfural (C22), p-xylene (C28), nonane (C34), alpha-pinene (C38), benzaldehyde (C40), and benzene, 1,3,5-trimethyl-(C48) were detected in 100% of the examined pine honey samples. [PERSON] et al. [32], analyzing 44 honey samples for the discrimination between Greek and Turkish pine honey, found the compounds octane (C21), p-xylene (C28), alpha-pinene (C38), benzaldehyde (C40), nonane (C34), furfural (C22), and 1-octene (C20) in 100% of Greek honey samples. Additionally, beta.-pinene (C44), which was found only in some pine honey samples in our study, was used by [PERSON] et al. [32], among other compounds, for the separation of Turkish and Greek honey classification. As for fir honeys, the compounds methyl butanal (isomer) (C1), cyclopentane, 1,3-dimethyl-(isomer) (C2), heptane (C3), furan, 2,5-dimethyl-(C4), cyclohexane, methyl-(C5), 3-buten-1-ol, 2-methyl-(C6), methyl isobutyl ketone (C11), disulfide dimethyl (C12), toluene (C16), 1-octene (C20), octane (C21), ethylbenzene (C26), p-xylene (C28), santene (C30), 2-heptanone (C32), nonane (C34), alpha.-pinene (C38), benzaldehyde (C40), benzene, 1,3,5-trimethyl-(C48), octanal (C53), benzene, 1,2,4-trimethyl-(C59), p-cymene (C61), 2-nonanone (C77), undecane (C79), nonanal (C80), decanal (C104), and tridecane (C115) were detected in 100% of the examined fir samples. [PERSON] et al. [40] also noted high concentrations of 1-octene and octane in honeydew honeys and nonanal in fir honeys. Santene (C30) was detected only in fir honeys, which is in agreement with the results of [PERSON] et al. [41], who found this compound in 100% of the analyzed fir honey samples (\(n=33\)). Lastly, in cotton honeys, the compounds toluene (C16), octane (C21), furfural (C22), and benzaldehyde (C40) were identified in the greatest percentages (14.64%, 10.78%, 6.60%, and 5.08%, respectively). Additionally, the compounds methyl butanal (isomer) (C1), cyclopentane, 1,3-dimethyl-(isomer) (C2), heptane (C3), cyclohexane, methyl-(C5), 3-buten-1-ol, 2-methyl-(C6), disulfide dimethyl (C12), toluene (C16), 2-buten-1-ol, methyl-(isomer) (C17), 2-butenal, 3-methyl-(C19), 1-octene (C20), octane (C21), furfural (C22), 1-pentanol, 4-methyl-(C23), 3-penten-1-ol, methyl-(isomer) (C27), p-xylene (C28), nonane (C34), ethanone, 1-(2-furanyl)-(C36), benzaldehyde (C40), 1-octen-3-ol (C47), benzene, 1,3,5-trimethyl-(C48), benzene, 1,2,4-trimethyl-(C59), D-limonene (C62), benzeneacetaldehyde (C64), benzene, 1-ethyl-2,3-dimethyl-(C67), octane, 1-chloro (C69), 2-furanmethanol, 5-ethenyltetrahydro-alpha,alpha,5-trimethyl-cis-(C73), benzene, 1-methyl-4-(1-methyletheryl)-(C75), undecane (C79), nonanal (C80), decanal (C104), triadecane (C115), naphthalene, 1,2-dihydro-1,1,6-trimethyl-(C117), and pentadecane (C123) were found in 100% of cotton honey samples, whereas the compounds, 1-butanol, 2-methyl-(C8), 2-butenal, 3-methyl-(C19), 1-pentanol, 4-methyl-(C23), 3-penten-1-ol, methyl-(isomer) (C27), 1-octen-3-ol (C47), 2-furanethanol,5-ethenyltetrahydro-alpha,alpha,5-trimethyl-cis-(C73), and benzene, 1-methyl-4-(1-methyletheryl)-(C75) were found in higher percentages in cotton honey, compared with the other studied honey types. The compound 2-furanmethanol, 5-ethenyltetrahydro-alpha,alpha,5-trimethyl-cis-(C73) was also reported in high concentrations in the study by [PERSON] et al. [48] and 3-penten-1-ol, methyl-(isomer) (C27) in the study of [PERSON] et al. [27]. Nonanal (80) and benzeneacetaldehyde (C64) are also referred in cotton honeys from other countries, such as Turkey and Palestine [90,91]. The use of P&T linked to GC-MS is widely used for the identification of volatile compounds in food science [92,93].
