 "The flowers of C.purpurascens (2n=34) are the most fragrant among the 20 species in the genus cyclamen. Although C.purpurascens has been grown among gardening devotees, unlike C.persicum it has not developed into a major commercial plant... Flowers of C.purpurascens had a rose- or hyacinth-like fragrance." \\
-The headspace of the flowers (species from the Cyclamen Society of the UK), trapped on Tenax TA, contained citronellol (17.8%), (E)-cinnamic alcohol (9.1%), methyl decanoate (4.9%), decane (3.7%), geraniol (3.0%), limonene (2.0%), linalool (1.6%), cinnamic aldehyde (1.2%), β-pinene (1.1%), and methyl citronellate (1.1%), as main components. Minor ones were eg. menthol, α-terpineol, benzyl alcohol, 3-phenylpropyl alcohol, nonanal, citronellal, geranyl acetone,methyl octanoate, methyl benzoate, benzyl acetate, methyl anisate, and phenol. \\

-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." \\
