摘要
To avoid the traditional and time consuming hydrodistillation, the analyses of volatile components in leaves of Citrus aurantium L. were carried out by a simple microwave distillation followed by headspace single drop microextraction (MD-HS-SDME) coupled to gas chromatography-mass spectrometry (GC-MS). The headspace volatile compounds were collected after irradiation using a single drop of n-heptadecan. The extraction conditions were optimized using the relative peak areas as index. The chemical composition of the MD-HS-SDME extracts was confirmed according to their retention indexes and mass spectra. Forty-one components were extracted and identified by using the MD-HS-SDME method. Limonene (62%), Linalool (7.47%), trans--Ocimene (3.47%), Caryophyllene (2.05%), - Bisabolene (1.8%) and Myrcene (1.18%) were the major constituents.
