对高压脉冲电场一超临界CO2萃取荔枝种仁精油及其影响因素进行研究，结果表明：种子含水量是影响精油萃取效率的主要因素。两者呈“S”型衰减指数关系。精油萃取率与萃取压力、萃取时间呈对数函数关系。在临界压力下，温度过高会因密度下降而使单位体积的萃取携带效率降低。

Seed Kernel essential oil from Litchi chinests was extracted with pulse high pressureelectric field-supper critical CO2. The extraction was mainly influenced by the water content in litchiseeds. There existed relationShip of a 'S' -type attenuate function between the extraction rate of the essential oil and the water content. The extracting rate of the essential oil was logarithmically increasedwith extracting pressure and time. Under suppercritical pressur...
