摘要
目的:确定亚贡叶中总酚酸提取工艺。方法:确定以溶媒量、提取时间、提取次数为考察因素,水回流法提取总酚酸,采用正交设计试验确定最佳提取工艺。结果:最佳提取工艺为水回流法提取3次,每次10倍量水提取20min。结论:该工艺条件稳定,简便易行,重现性好,适于亚贡叶中总酚酸提取。
Objective: To confirm the extract method of Orthogonal design was used for exploring the main factors of extract total phenolic acids in yacon leaves. Methods: method. Results: The optimal extraction procedure of total phenolics was established as the materials was refluxed with ten times amount of water for 3 times, 20 minutes for each. Conclusion: The established method showed good stability and reproducibility and could be used as a method for extracting total phenolic acids in yacon leaves.
