摘要

目的：优选超临界CO2萃取联合水蒸气蒸馏法提取柴胡挥发油的工艺条件。方法：以挥发油得率为指标，采用正交试验与单因素试验考察萃取釜与分离釜的温度、压力等因素对柴胡挥发油提取工艺的影响，采用GC-MS分析不同方法提取的柴胡挥发油中成分差异性。结果：最佳工艺条件为CO2流速约20 kg·h-1，萃取釜压力20 MPa，温度35 ℃，分离釜I压力12 MPa，温度40 ℃，分离釜Ⅱ压力6 MPa，温度25 ℃。水蒸气蒸馏法、超临界萃取联合水蒸气蒸馏法提取挥发油的得率分别为0.07%，1.4%，化学成分基本一致。结论：优选的提取工艺简单可行，可显著提高柴胡挥发油的得率。

Abstract

Objective: To optimize process conditions of volatile oil from Bupleuri Radix by supercritical CO2 fluid extraction combined steam distillation. Method: Extraction process was optimized by single factor tests and orthogonal design by taking yield of volatile oil as index

some factors were investigated such as temperature

time and pressure of extraction and separation kettle

GC-MS was adopted to identify difference of chemical components in volatile oil by different methods. Result: Optimum extraction conditions were as follows:CO2 velocity about 20 kg·h-1

pressures of extraction kettle

separation kettle I and II were 20

12 and 6 MPa

temperatures were 35

40 and 25 ℃

respectively.Compared with steam distillation(0.07%)

yield of volatile oil with combination increased by 20 times and chemical components were similar to each other. Conclusion: This optimized process was simple and feasible

which could significantly improve yield of volatile oil from Bupleuri Radix.
