Composition of the floral waxes ofRosa gallica, Jasminum grandiflorumm, andViola odorata

The chemical compositions of the waxes of the flowers ofRosa gallica L., Jasminum grandiflorum L., andViola odorata L. have been characterized. The waxes of these plants mainly contained hydrocarbons and fatty and cyclic alcohols and their esters with fatty acids. The highest level of free fatty acids (12.4%) was found in theJ. grandiflorum wax. Depending on the plant species, the above-mentioned groups of substances differed in composition and amount, but hydrocarbons predominated.
