摘要

目的: 优选微波法提取土木香根中土木香内酯和异土木香内酯的工艺条件。方法: 以土木香内酯和异土木香内酯含量为指标

通过单因素试验和正交试验考察乙醇体积分数、料液比、微波辐射时间和提取温度等因素对提取工艺的影响

采用HPLC测定指标成分含量。结果: 土木香内酯和异土木香内酯的最佳微波提取工艺为乙醇体积分数90%

料液比1:15

微波时间180 s

提取温度45 ℃。结论: 优选的微波提取工艺具有稳定可行、节约时间、能耗低等优点。

Abstract

Objective: To optimize microwave-assisted extraction technology conditions for alantolactone and isoalantolactone from roots of Inula helenium. Method: With the content of alantolactone and isoalantolactone as indexes

which were determined by HPLC

effects of the concentration of ethanol

liquid-solid ratio

extraction time and temperature on technology was investigated by single factor test and orthogonal test. Result: Optimal technology conditions described as followings:microwave extracted 180 s with 15 times the amount of 90% ethanol at 45 ℃. Conclusion: This optimized technology was stable and feasible with low energy consumption and time saving.
