Event Title

Extraction of Essential Oils from Rose Petals and Characterization of its Fragrant Chemical Components of by GC-MS and Comparison with the Essential Oils from Commercial Samples

Abstract

Essential oils of large number of natural products, mostly flowers, are used extensively in perfume and cosmetic industry. These oils are employed in aroma therapy. Several synthetic perfumes use chemicals found in these essential oils and serve the same purpose of making perfumes and other fragrant products.

In this project, the essential oils are extracted from rose petals of different samples of rose flowers by steam distillation extraction The essential oils are analyzed for their chemical constituents by Gas Chromatography-Mass Spectrometry (GC-MS). Essential oils are separated by the GC-MS techniques by first developing a method of separation of chemical components of the oils and then by analyzing by the mass-spectrometry and by comparisons of retention times of chemical components of the essential oils with the retention times of the standard samples. Fragrant chemical components of commercial sample of rose oil are also separated and characterized by GC-MS. Geraniol, eugenol, citronellol, phenylethanol, linalool, caryophyllene, aristolene are among the chemical components of the commercial oil. The future work includes extraction of rose petal by solvent extraction.
