Natural aromatic essential oil acquisition apparatus and application method

The invention relates to a natural aromatic essential oil acquisition apparatus and method. The acquisition apparatus is composed of a humidifying air generator, a sample acquisition chamber and a volatile component condensing and receiving device. Compressed air is filtered by active carbon; then water is introduced for humidification; humidified air enters into a sample chamber, and gas carrying plant volatile components is successively placed in an aqueous glycol solution cold trap and a dry ice-ethanol cold trap for condensation and collection. Volatile essential oil acquired and obtained by using an air humidification method has an aromatic degree close to that of natural flower fragrance. According to results of gas chromatography-mass spectrometry, the method provided by the invention has the following advantages compared with traditional methods like a headspace sampling method: a volatile matter contains more components, and the boiling range of a compound is increased. Through gas chromatography or gas chromatography-mass spectrometry of a concentrate of the volatile components, compositions of the natural aromatic essential oil can be determined; and results of the gas chromatography or gas chromatography-mass spectrometry can be used for physiological and genetic research on flowers and the like based on analysis of the compositions of the essential oil.
