摘要
利用超临界CO2萃取装置,采用动态萃取的方法,研究了压力、温度、萃取时间等因子对花椒挥发油萃取的影响,为规模化生产及其相关研究提供了科学依据。研究表明,样品200g粒度40目,最佳的萃取条件为:压力33MPa,温度55℃,时间1.0h,花椒挥发油萃取率为10.2%。气-质联用分析花椒挥发油结果表明,挥发油为3-甲基-2氮杂芴、γ-萜品烯、3-蒈烯等31种化合物组成。其中3-甲基-2-氮杂芴含量最高,达到18.63%。
The volatile oil from Zanthoxylum bungeanum Maxim. cv. Dahongpao has been associated with various pharmacological activities. A systematic method was used to optimize the supercritical carboon dioxide extraction (SCDE) of the volatile oil. Overall 3 variables (pressure, temperature, extracting time) were considered. The optimized conditions were: temperature 55 ℃, pressure 33 MPa, time 60 min. Thirty one chemical components of the volatile oil were determined qualitatively and quantitatively by GC-MS. Among them the content of 3 methyl-2- ozafluorene is the highest, about 18.63 % .
