# The Scent of _Himantoglossum_ Species Found in Basilicata (Southern Italy)
## 3 Results  
The SPME analysis of scent of _H. hircinum_ showed the presence of elemicin (spicy, floral scent) as the main component (61.71%) in the presence of a relevant amount of eugenol (4.50%) (Table 2). Minor products observed in the scent were 3,4,5-trimethoxybenzaldehyde, benzyl benzoate, 3-(4,8,12-trimethyltridecyl)furan, and 9-tricosene. All the values are based on per cent of the TIC area. \begin{table}

The scent of the sample of _H. adriaticum_ collected in Abruzzo (Sample 1) showed the presence 4-amino-5-(4-morpholinylmethyl)-2-oxazolidinone, \(\beta\)-ocimene (green tropical woody floral vegetable scent), decyl decanoate, and 9-tricose as main components (17.37, 8.23, 5.36, and 6.41%, respectively) (Table 2). Furthermore, several compounds are presents in relevant amounts: 1-methoxy-4-methylbenzene (1.63%), geraniol (1.49%), geranyl acetate (1.43%), methylteugenol (2.34%), pentadecane (2.98%), elemicin (2.95%), hexadecane (2.70%), heptadecane (2.11%), benzyl benzoate (2.17%), 6,10,14-trimethyl-2-pentadecanone (1.83%), and 11-hexadecen-1-ol acetate (2.42%). The sample of _H. adriaticum_ collected at Marsico Nuovo (Sample 2) has an aroma where the main component was pentadecyl hexanoate (22.73%), 9-tricose (5.06%), methylteugenol (5.93%), tetradace (3.93%), pentadecane (3.41%), and elemicin (3.80%) (Table 2). The samples of _H. adriaticum_ collected at Viggianello (samples 3 and 4) showed some similarities in the scent: the main components were 9-tricosene (31.21% in sample 3 and 40.22% in sample 4) and methylteugenol (18.06% in sample 3 and 4.73% in sample 4) (Table 2).
