摘要 研究微波辐射法从厚朴皮中提取总酚。以总酚得率为指标,通过单因素试验和正交试验对厚朴皮总酚的提取工艺进行优化。确定其最佳提取工艺为以体积分数为70%的乙醇溶液作为提取溶剂、微波辐射时间6min、微波功率40%(即240W)、料液比1:20(g/mL)。在此条件下,总酚得率6.34%。 Microwave radial extraction method was applied to extract total phenols from magnolia bark using extraction rate of total phenols as evaluation index. The effects of extraction conditions on extraction rate of total phenols from magnolia bark were evaluated by single factor and orthogonal tests. The optimal extraction process parameters include 70% alcohol as extraction solvent, microwave radial time of 6 rain, microwave power of 40% (240 W), and material-liquid ratio of 1:20 (g/mL). Under the optimal extraction conditions, the extraction rate of total phenols was up to 6.34%.
