## 3 Results and Discussion
### Volatile Compounds
Furthermore, we can also note the presence of benzeneethanol in significant amounts in the case of the honey samples from Zone 2 (3.58%), Zone 1 (2.78%) and Zone 3 (2.37%). Benzenethanol and benzoic acid were identified as rape honey markers [74]. Alcohols constitute an important part of Romanian honey samples reaching values of 28.35% in Zone 3, 23.87% in Zone 2, 19.13% in Zone 1. The alcohols present in all the zones were ethanol, 2-propanol, 2-methyl-3-buttene-2-ol, isoamyl alcohol, 3-methyl-3-buttene-1-ol, 2-methyl-2-buttene-1-ol, _cis_-3-hexen-1-ol, 2-ethyl-1-hexanol, linalool, hotrienol, _alfa_-terpienol, benzeneethanol, benzenemethanol, phenol. Among the identified alcohols, ethanol, benzeneethanol, 3-methyl-3-buttene-1-ol proved to have the highest area percentage of all the analyzed samples (Table 8). Alcohols represent important markers of honey; alcohols, such as 3-methyl-3-buttene-1-ol and 2-methyl-2-buttene-1-ol were described as adding a fresh aroma, their presence in honey being associated with different floral origins [64]. Ethanol, 2-methyl-propanol and 3-methyl-3-buttene-1-ol were \begin{table}
