Progress in Essential Oils

Rose Oil and Extracts

Although rose oil and extracts are produced from more than one species of rose, this review is totally devoted to Rosa damascena Mill., which is grown commercially in Bulgaria, Turkey and to a lesser extent, India and Morocco. Lindström and Jaquier (1993) analyzed a sample of Bulgarian rose oil to determine the enantiomeric distribution of a number of constituents.

The authors noted that camphor, (E)- α-ionone and the two theaspiranes had not previously been identifi ed in rose oil. This fi nding was important because α-ionone and the two theaspiranes could probably contribute to the complex aroma characteristics of Bulgarian rose oil as they are strong smelling compounds.

Brud and Konpacka-Brud (1994) compared the composition of one sample of Bulgarian and two samples of Turkish rose oils. The results of this comparative study are shown in T-1. The authors also repeated the results of an earlier report of Ohloff (1978) in which the important odor constituents of six components were compared as shown in T-2.
