| "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." \\ |
| | "(2E,6Z)-nona-2,6-dien-1-ol and which, with its intense, oily-green, herbaceous-vegetable odor typically reminiscent of violet leaves and freshly cut cucumbers, also constitutes a character-determining odorant of violet leaf oil. Its corresponding aldehyde, known as ‘violet leaf aldehyde’ and not to be confused with leaf aldehyde, has strong, fatty green odor also reminiscent of violet leaves and cucumber and is the main constituent of the volatile fraction of violet leaf absolute." \\ |

| "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.
