摘要

Rosa damascena Mill. is an important aromatic plant for commercial production of rose oil, water, concrete and absolute. The rose water and rose oil produced under the mountainous conditions of Uttarakhand were investigated for their chemical composition. The major components of rose water volatiles obtained from the bud, half bloom and full bloom stages of cultivar 'Ranisahiba' were phenyl ethyl alcohol (66.2-79.0%), geraniol (3.3-6.6%) and citronellol (1.8-5.5%). The rose water volatiles of cultivar 'Noorjahan' and 'Kannouj' also possessed phenyl ethyl alcohol (80.7% and 76.7%, respectively) as a major component at full bloom stage. The essential oil of cultivar 'Noorjahan' obtained from two different growing sites was also compared. The major components of these oils were citronellol (15.9-35.3%), geraniol (8.3-30.2%), nerol (4.0-9.6%), nonadecane (4.5-16.0%), heneicosane (2.6-7.9%) and linalool (0.7-2.8%). This study clearly showed that the flower ontogeny and growing site affect the composition of rose volatiles. The rose oil produced in this region was comparable with ISO standards. Thus, it was concluded that the climatic conditions of Uttarakhand are suitable for the production of rose oil of international standards.
