Investigation of Floral Scent and Essential Oil of Rosa iberica Petals

The flowers of wild Rosa iberica are investigated to find the chemical constituents of its aroma and essential oil. The measurements were carried out by GC-FID and GC-MS analysis. The aromatic compositions emitted from the flowers revealed 11 constituents, among which phenyl ethanol (38.82%), benzyl alcohol (28.48%), and geraniol (12.57%) were the most abundant. The essential oil investigation detected 13 compounds, the most abundant ones being anethole (45.56%) and phthalic acid (32.23%). The scent and essential oil detected de novo in the petals of R. iberica are beneficial as natural ingredients in seasonings, therapeutic compositions, and an aromatic plant in breeding strategies of ornamental shrubs and flowers.
