| "Viola odorata flowers give 0.003% essential oil. According to older information, the oil contains benzyl alcohol, 1-hexanol, 2,6-nonadienal (violet leaf aldehyde), 2,6-nonadienol. Fragrance principle is parmon = (E)-α-ionone, as (R)-(+)-enantiomer (99.9%)." \\ | "Viola odorata flowers give 0.003% essential oil.

| | β-Ionone, dihydro-β-ionone (th 1.7 ng/l air), (+)-(R)-α-ionone (th 3.2 ng/l air), (+)-(R)-dihydro-α-ionone (th 31 ng/l air), and dehydro-ɣ-ionone are main components of violet flower oil. "Apart from (2E,6Z)-nonan-2,6-dienal (1.9%), the flower oil does not contain any metabolites of fatty acids in sizable quantities. The sesquiterpene hydrocarbons (-)-zingiberene and and (+)-α-curcumene are major constituents (35%) of the flower oil as well." \\ |

| "Genome-wide and in vitro assays demonstrate rs6591536 as the causal variant for β-ionone odor sensitivity. rs6591536 encodes a N183D substitution in the second extracellular loop of OR5A1 and explains >96% of the observed phenotypic variation, resembling a monogenic Mendelian trait. Individuals carrying genotypes for β-ionone sensitivity can more easily differentiate between food and beverage stimuli with and without added β-ionone. Sensitive individuals typically describe β-ionone in foods and beverages as “fragrant” and “floral,” whereas less-sensitive individuals describe these stimuli differently. rs6591536 genotype also influences emotional associations and explains differences in food and product choices." \\ | "Genome-wide and in vitro assays demonstrate rs6591536 as the causal variant for β-ionone odor sensitivity. rs6591536 encodes a N183D substitution in the second extracellular loop of OR5A1 and explains >96% of the observed phenotypic variation, resembling a monogenic Mendelian trait.
