| 中文摘要: |
| 利用超声波辅助法,选择4个考察因素对荠菜总黄酮进行提取,采用500 nm检测波长测定提取液中总黄酮的含量,通过单因素和正交试验法确定荠菜中总黄酮的最佳提取工艺条件:溶剂为70%的乙醇,料液比为1∶5,温度为50℃,时间为30 min.在最佳工艺条件下,超声辅助法提取荠菜总黄酮提取率达1.35%.超声辅助提取具有省时、节能、高效等优点,适合工业化生产. |
| 英文摘要: |
| The paper is on the optimum extraction technology of total flavonoids from Capsella bursa-pastoris.The ultrasound-assisted method was used to extract the total flavonoids from Capsella bursa-pastoris.The extraction of total flavonoids was chosen four studying factors.The extraction process was optimized with the orthogonal design using spectrophotometric to determine total flavonoids content at 500 nm wavelength.The optimum extracting process conditions were as follows: extraction solvent 70% ethanol,solid-liquid ratio of 1∶5,extraction temperature of 50 ℃,extraction time of 30 min.Under the condition of the optimum technology,the extraction rate of total flavonoids from Capsella bursa-pastoris by ultrasound-assisted method was 1.35%. |
