Violet Leaf Absolute Chemical Properties,Usage,Production
Chemical Properties
Violet leaf absolute is obtained by solvent extraction, via the concrete, from
the leaves of Viola odorata L. (Violaceae). It is produced in small quantities, for
example, in Egypt.
Theabsolute is a dark green to brown liquid with a strong, green odor.Themain
constituent of the volatile fraction is (2E,6Z)-2,6-nonadienal (violet leaf aldehyde).
Violet leaf absolute is used frequently in perfume compositions, but only in very
low concentration because of its intense odor.
Chemical Properties
Violet leaf absolute is produced by petroleum extraction of the freshly harvested leaves. Further alcohol washing, chilling and filtration of the alcohol extracts and subsequent evaporation in a vacuum results in the absolute. The absolute has a very powerful and characteristic odor. Also see Violet.
