QUALITATIVE ASSAY OF ESSENTIAL OILS IN COMMERCIAL LAVENDER OIL BY GC-MS METHODAbstract
Essential oils are largely employed for their therapeutic properties, being marketed extensively in pharmaceutical and cosmetic industry. Lavender oil is known for its excellent aroma. Therefore, it is extensively used in the cosmetic, perfumery, and flavour industries. The lavender oil is known to possess sedative, carminative, antidepressive, and anti-inflammatory properties. The aim of our study was to assess the purity and quality of lavender oils, available on the market from various commercial producers. Therefore, essential oil compositions of lavender oil were analyzed using gas chromatography-mass spectrometry (GC-MS). Chromatographic analyses were carried out on HP-5 MS column. The injector volume was 1 µl in split mode (40:1) and the carrier gas was helium at a flow rate of 0.8 ml/min. 33 essential chemical constituents were identified based on GC-MS in lavender oil supplied from an herbalist. The major components of the lavender oil were found linalyl acetate (37.82 %), linalool (33.07 %), eucalyptol (4.88 %), camphor (4.07 %), lavandulol acetate (1.53 %) and caryophyllene (1.43 %).
