Volatile oil composition of Rosa damascena Mill. (Rosaceae)

Abstract

The volatile oil obtained by hydrodistillation of the petals of Rosa damascena Mill. (Rosaceae) was analyzed by gas chromatography and gas chromatography/mass spectrometry(GC/MS). The yield of the oil was 0.12 % (v/w). Fifty compounds representing 99.06 % of the oil were characterized. The volatile oil was found rich in sesquiterpenes and aliphatic components, consisting of two monoterpenic esters (0.44 %), nineteen sesquiterpenes (44.05 %), twenty nine aliphatic compounds (54.57 %) including n-octadecanol, n-hexacosane, n-octacosane and n-nonacosane (26.31 %).
