Abstract
One of the basic utilizations of rose flowers is the production of essential oil for the medicinal,
cosmetic, food industry, perfumery, and some other purposes. In this research
article, the two samples of Rosa damascena var. trigintipetala from two different places Alhada and Alshifa of Taif
region of Saudi Arabia were studied for the yield of oil using the
hydro-distillation technique of extraction along with the quality of oil in
relation to the proportion of citronellol and geraniol. Also, the comparison of
fresh flowers with non-fresh (used) flowers were also made to consider the
effectiveness of extraction techniques. The fresh samples from Alhada (A1) were
found to give double the yield (0.5 ml/kg) of essential oil than samples from
Alshifa (B1) (0.25 ml/kg). The fresh samples from Alshifa were found to contain
a better amount of citronellol (17.55 %) and geraniol (1.014%) than Alhada
which indicate that the oil production is more in the plane and hot climatic
conditions while the geraniol and citronellol content is influenced by high
altitude and cool climate. Alhada samples showed the presence of 34 compounds
including alkanes, monocyclic, and acyclic isoprenoids, and out of these
25 were identified. The compounds ranged from C8-C23
while Alshifa samples possess 52 compounds and out of which 43 were identified
ranging from C10 -C23. The extraction of oil from
exhausted flowers suggests that the extraction techniques used on a commercial
scale in the Taif region need to be refined to
increase the production and eventually the
revenue.
Keywords
Rosa damascena, essential
oil, geraniol, citronellol, GC-MS.
