【摘要】 对几种不同的从甘草中提取甘草酸的提取方法进行了实验比较. 结果表明, 微波辅助提取法与热回流法、索氏(Soxhlet)提取法、室温提取法等传统方法相比，具有提取高效、快速、完全及节省时间、溶剂和能耗等优点, 是一种适于从甘草中快速提取甘草酸的新方法.更多还原

【Abstract】 Comparison of extraction methods for isolation of glycyrrhizic acid from G. uralensis Fisch is presented. The experiments show that microwave-assisted extraction (MAE) was more effective than the conventional techniques such as heat reflux extraction, Soxhlet extraction and extraction at room temperature. Due to the short extraction time and low consumption of solvent and energy, MAE technique is suitable for fast extraction of a variety of licorice-containing products.更多还原
