摘要

目的: 探讨超临界CO2萃取云南香樟叶中右旋龙脑的工艺条件。方法: 采用气相色谱法测定右旋龙脑含量

设计L9(34)正交试验考察萃取压力、温度、流量

单因素考察时间对右旋龙脑萃取率的影响。结果: 优选的萃取条件为压力30 MPa

温度45 ℃

二氧化碳流量20 L·h-1

萃取时间90 min。结论: 优选的最佳工艺萃取率高

是具有相当发展潜力的提取分离方法。

Abstract

Objective: To investigate the technology condition of dextroborneol from Cinnamomum camphora leaves in Yunnan by supercritical CO2 fluid extraction. Method: The content of dextroborneol was determined by gas chromatography(GC)

to analysis the conditions of pressure

temperature

CO2 flow rate by orthogonal test and analysis extraction time by single factor test. Result: The optimum extraction condition was as follows:extraction pressure was 30 MPa

extraction temperature was 45 ℃

CO2 flow rate was 20 L·h-1

extraction time was 90 min. Conclusion: The optimum extraction technology had high extraction yield

and it was a extraction and separation method which had considerable potential for development.
