摘要: [目的]研究菊科植物猪毛蒿醇提物的最佳提取工艺条件。[方法]采用冷凝管回流提取法,以乙醇作为提取溶剂,以提取温度、乙醇浓度、料液比、提取时间为关键提取条件,采用四因素三水平设计正交试验,根据提取物得率确定猪毛蒿醇提物的最佳提取工艺。[结果]分析方差和极差R值表明,4个因素对猪毛蒿醇提物得率影响的主次顺序是:提取温度>乙醇浓度>提取时间>料液比;提取温度对提取物得率影响差异极显著(P<0.01),是影响猪毛蒿乙醇提取效果的主要因素,乙醇浓度、料液比、提取时间对提取物得率影响差异不显著(P>0.05),是影响提取效果的次要因素。确定猪毛蒿有效成分的醇提物最佳提取工艺条件是:乙醇浓度65%,料液比1∶7,提取温度75 ℃,提取时间3.0 h。[结论]在实验室条件下,确定了猪毛蒿醇提物的最佳提取工艺条件,为猪毛蒿提取物及其生物活性成分的进一步研发与应用提供了参考。

Abstract: [Objective] To determine the optimal preparation conditions of ethanol extracts from Artemisia scoparia, a compositae plant. [Method] The extracts from Artemisia scoparia were prepared by the condensation tube reflux extraction method with ethanol as extraction solvent. A orthogonal test was designed by four factors (extraction temperature, ethanol concentration, solid-liquid ratio, and extraction time) with three levels respectively. The optimal preparation conditions were determined according to the yield of ethanol extracts. [Result] According to the analysis of variance and range R value, orders of the extraction effects of the four factors on yield of ethanol extracts of Artemisia scoparia was as follows, extraction temperature > ethanol concentration > extraction time>solid-liquid ratio. The influence of extraction temperature on yield of ethanol extracts was extremely significant (P<0.01), revealing that it was the primary factor impacting the extraction effect. The ethanol concentration, solid-liquid ratio, and extraction time had no significant (P>0.05) effects on yield of ethanol extracts, demonstrating that they were the secondary variables impacting the extraction effect. The optimal preparation conditions of ethanol extracts from Artemisia scoparia were ethanol concentration at 65% with a 1∶7 solid-liquid ratio, and 3.0 h of extraction at 75 ℃. [Conclusion] This study determined the optimal preparation parameters for ethanol extracts from Artemisia scoparia under laboratory conditions, providing a reference for further research and application of extracts and bioactive components of Artemisia scoparia.
