摘要:

为提高水芹中黄酮的提取效率,以黄酮得率为考察指标,采用单因素和正交试验研究总黄酮快速萃取的工艺条件。结果表明:乙醇为最佳提取溶剂,总黄酮快速萃取的条件为乙醇体积分数60%、提取温度100℃、每次提取时间5min、提取次数为3 次,黄酮得率为3.64%。快速萃取工艺不仅能缩短提取时间,还能提高水芹中黄酮的提取率。

Abstract:

In order to improve the extraction efficiency, the extraction processing of total flavonoids from Oenanthe javanica was optimized by single factor and orthogonal experiments based on the extraction rate of total flavonoids as an evaluation index. Results indicated that the optimal extraction processing parameters were ethanol concentration of 60%, extraction temperature of 100 ℃, extraction time of 5 min and repeated extraction number of 3. Under the optimal extraction conditions, the extraction rate of total flavonoids was 3.64%. This accelerated solvent extraction method has the advantages of shortening extraction time and improving extraction rate of total flavonoids.

Key words: Oenanthe javanica, flavonoids, accelerated solvent extraction
