-The strong and attractive rosy-floral scent of wild cyclamen growing in the Alps is based on linalool, citronellol (30.5%), nerol (1.6%), geraniol (13.9%), citronellal (0.5%), neral (0.1%), geranial (0.2%), (E)-2,3-dihydrofarnesal (0.4%), (E)-2,3-dihydrofarnesol (1.1%), (E,E)-farnesol (11.2%), and (E)-cinnamic alcohol (0.2%). "...somewhere between the scents of centifolia rose and lily of the valley. Minor amounts of decano-4-lactone, methyl citronellate, and prenyl benzoate finally give the twist to the unmistakable scent of Cyclamen purpurascens, a knowledge also applicable in the creation of fragrances." \\

+"C.purpurascens had a floral fruity note and contained 62 compounds, the highest number among all the wild species evaluated in this study. The major compounds were citronellol (39.34%) and (E)-2,3-dihydrofarnesol (11.7%). Other components were detected, such as geraniol (4.6%), linalool (1.58%) and nerol (3.71%) (which
+were the sources of a floral note) and methyl citronellate (0.96%), (E)-2,3-dihydrofarnesal (0.28%) and (Z)-2,3-dihydrofarnesal (1.57%). These latter three compounds have a strong floral scent, even in extremely low quantities, because of their high olfactive capacity." \\
