Abstract
For perfume industry, Rosa damascena Mill. is the most important species used in the production of rose attar, which is made by distilling v volatile oils from the petals of flowers. Eight landraces of Damask rose and four related rose species were collected from Punjab province and their oil constituents were determined by using GAS chromatograph. The major components identified were citronellol (8.32-2.31%), farnesol (6.62%-0.78%), geraniol (5.43-0.42%), eugenol (3.72%-0.42%), citral l mixture of cis and trans (5.12-0.23%), 2- phenethyleacetate (2.53-0.22%), linalool (1.35-0.23%), nerol (1.33- 0.81%), citronellyle acetate (2.53-0.12%), phenethyl alcohol (5.43-0.52%), benzyle alcohol (3.12-0.31%) and benzaldehyde (3.12-0.32%). The variation in oil constituents in rose oil from different essential oil Rosa species was due to the morphological variations and genetics. (C) 20012 Friends Science Publishers
