Study on characteristic aroma components of lavender essential oils
Abstract: Two lavender essential oils,Xinjiang lavender No.1 and Xinjiang lavender No.2,were analyzed both by using gas chromatography-mass spectrometry (GC-MS) and gas chromatography - diluted frequency analysis (GC-O) .Eighty volatile components of lavender essential oils were analyzed and identified by GC-MS. Thirty-one aroma compounds of lavender essential oils were identified by GC-O-AEDA, among which eleven terpenes, ten alcohols, six esters, two aldehydes, one ketone as well as one other compound. Through using “single point correction method” similar to the standard addition method,these aroma compounds from lavender essential oils were calculated.Quantitive data of the identified aroma compounds were obtained from calculating their relative quantitative correction factors. Finally, the characteristic aroma components of Xinjiang lavender essential oils are linalool, linalyl acetate and β- myrcene,respectively.
