Viola odorata

Violet Leaf. Violet leaf absolute is produced by the usual extraction methods from Viola odorata (var. Victoria). It is grown mainly ia the south of France and Egypt. Although this material is not produced ia large amounts, it is quite valuable ia perfumery for its powerhil green leafy and doral character, an odor that belongs to many doral bouquets. The principal odorant ia violet leaf absolute is 2-/n j -6-i7j -nonadienal [55748-2]. 

Violet leaf absolute is obtained by solvent extraction, via the concrete, from the leaves of Viola odorata L. (Violaceae), which is grown predominantly in southern France. 

Seeds of the violet, Viola odorata are disseminated by the ant Aphaenogaster rudis. Elaiosomes (appendages attached to the outside of the seed coat) often contain high concentrations of lipids and are associated with attraction of the ants. 1,2-Diolein, a diglyceride, is largely responsible for this attraction (124). 

A, a recently discovered cyclotide derivative from the plant Viola odorata, has a point mutation at the C-terminal residue of the mature peptide (Lys instead of Asn) and is a linear peptide as a result. NMR studies show that its lack of a circular backbone leads to flexibility at the N-terminus, although it features a cystine-knot motif and is otherwise structurally similar to cyclotides.121...

Irenes are fragrances in the oil of the dried rhizomes of various Iris species cultivated in Italy and Morocco Iris germanica, I. florentina, I. pallida, Liliaceae) which is misleadingly referred to as oil of violet because of its pleasant violet-like odor. In fact, ionones (C13, section 7.4) which belong to the class of megastigmanes and not irones (Cu) are the shaping fragrances of violets Viola odorata, Viola-ceae). 

In the 19th century, the scent of violets enjoyed a renaissance. By enfleurage of the English violet (or wood violet, Viola odorata L) (Fig. 3.13), the readily volatile components were extracted and thus made accessible for fine perfumery. The price for one kilogram of violet oil in 1904 was estimated at 80,000 German Goldmarks, which corresponds to about 400,000 Euro. [48]...
