In this paper, the extraction method, physical and chemical properties, separation and purification technology, anti-oxidation and lavender essential oils microencapsulation technology of lavender essential oil was studied.Selection of the organic solvent extraction and ultrasonic method of extracting a lavender dried flowers, systematic analysis of the impact of lavender essential oil extraction rate of the major factors.Will be extracted from the lavender oil for the relative density, refractive index, polarimetry degrees, 70% (V / V) of ethanol in the mixed solution, such as acid number of indicators.Use of column chromatography separation and purification of the market lavender essential oil, after the purification of lavender oil for GC-MS analysis, which identified the major components and major components of the relative percentage of, and the essential oils of Weifen Li And the major components of the major components of the percentage of comparison.Lavender essential oils in the antioxidant components extraction; paper also adopted theβ-CD package of technology on oil for the inclusion of the micro-capsule package of technical parameters were optimized, the results showed that:lavender essential oil was extracted with organic solvent method in the best conditions for the extraction process: organic solvent n-hexane for the expected ratio of 1:15, the extraction time for 4 h, smashed head of a 40. Using ultrasonic lavender essential oil extracted in the best conditions for the extraction process: Ultrasound time is 45 minutes, ultrasonic frequency is 45 KHz, ultrasound temperature is 50℃, ultrasonic power is 80 W. The volatile oil extraction rate is 3.5%.The results of different absorbent, eluent allocated proportion to aspic volatile oil separation purification showed that: the separation column chromatography results were relatively good, and The best eluent allocated proportion is 88:12 .The best extraction technological conditions of Aspic dried flowers oxidation resistance ingredient: The ethyl alcohol density is 60%, The material fluid ratio is 1:25, extraction temperature is 40℃, and extraction time 1h. Through ultrasonic wave extraction process orthogonal experiment, the best technological conditions of aspic dried flowers oxidation resistance ingredient extraction:the best technological conditions of beta - link dextrin package gathers the aspic volatile oil : beta - The link dextrin: the volatile oil proportion is 8: 1, the temperature for 45℃, the time is 1.5h, the embedding rate is 64.49%.
