ANALYSIS OF ESSENTIAL OILS IN COMMERCIAL GERANIUM OIL BY USING GC-MS TECHNIQUEAbstract
Essential oils are largely employed for their therapeutic properties, and marketed extensively in the pharmaceutical and cosmetic industry. Geranium oil is a floral substitute for rose essential oil with its pungent rose-like odor and is one of the most valuable essential oils. Favorable quality properties make the geranium essential oil exigible for food industry applications. Our study aimed to assess the purity and quality of geranium oil available from various commercial producers. The gas chromatography-mass spectrometry (GC-MS) technique was used to detect and quantify the volatile constituents of geranium essential oil. 40 (fourty) volatile compounds were determined by the GC-MS method. The most abundant compounds were determined as geraniol (27.98%), citronellol (20.71%), isomenthone (6.57%), geranyl formate (6.52%) and linalool (6.38%).
