摘要

目的: 利用星点设计-效应面法优选紫荆皮挥发油的提取工艺。方法: 以挥发油提取量为因变量，在单因素试验基础上，选取浸泡时间、提取时间、加水量为自变量，通过对不同因素各水平的多元线性回归及二项式拟合，采用星点设计-响应面法优选紫荆皮挥发油的提取工艺，并进行预测分析。结果: 挥发油的最佳提取工艺条件为浸泡时间1 h，提取时间5 h，加水量14倍;挥发油提取率0.8%，挥发油平均质量0.391 2 g，与预测值（0.391 5 g）的偏差较小。结论: 优选的提取工艺简便合理、稳定、可预测性良好。

Abstract

Objective: To optimize extraction technology of volatile oil from Cortex Cercis Chinensis by central composite design and response surface methodology. Method: With yield of volatile oil as dependent variable

based on single factor tests

central composite design-response surface methodology was adopted to optimize extraction technology by taking soaking time

extraction time and the amount of water as independent variables

through multiple linear regression and binomial fitting of each level of independent variables to prediction analysis of extraction technology. Result: Optimum process conditions were as follows:soaked 1 h with 14 times the amount of water

extraction time 5 h;Yield of volatile oil was 0.8%

average mass of volatile oil was 0.391 2 g with a small deviation between the predicted value(0.391 5 g). Conclusion: This optimized extraction process was simple and reasonable with a good predictability.
