摘要: |
目的 优化离子液体辅助超声波法提取猫眼草中的黄酮工艺,为进一步提取猫眼草中的黄酮类化合物提供依据。方法 以离子液体为提取溶剂,辅助超声波法提取猫眼草中的黄酮。依次改变离子液体的种类、浓度,提取溶剂总体积与药材质量比,超声时间,超声温度。以总黄酮提取率为指标,确定单因素最佳条件,在单因素试验结果的基础上结合响应曲面设计优化最佳提取条件,再用HPLC测定山柰酚和金丝桃苷的含量探究不同离子液体对猫眼草中黄酮提取的变化规律。结果 最佳提取条件:离子液体种类为1-丁基-3-甲基咪唑溴盐、离子液体与醇的体积比为1∶6、提取溶剂总体积与药材质量比为50∶1、温度为40℃、超声时间为1h。在最佳条件下提取率为(15.8±0.9)%,相比传统提取率5.14%,提取率明显增加。结论 用离子液体法提取猫眼草植物黄酮可行。黄酮提取率与离子液体母核碳链长短不成正相关性。 |

Abstract: |
OBJECTIVE To optimize the process of extracting flavonoids from Euphorbia lunulata Bge by ionic liquid assisted ultrasonic method, and provide a basis for further extraction of flavonoids in Euphorbia lunulata Bge. METHODS Using ionic liquid as extraction solvent, extract flavonoids from Euphorbia lunulata Bge assisted with ultrasound method. The species and concentration of ionic liquids, the ratio of total volume of extracted solvent and the mass of medicinal materials, ultrasonic time, ultrasonic temperature were changed in turn. Taking the flavonoid extraction rate as the index, the optimal conditions of the single factor were determined, optimize the optimal extraction conditions based on the single factor experimental results combined with the responsive surface design. The contents of kaempferol and hypericin were then determined by HPLC to investigate the changes of different ionic liquids on flavonoid extraction in Euphorbia lunulata Bge. RESULTS The optimum extraction conditions: the type of ionic liquid was 1-butyl-3-methylimidazole bromide, the volume ratio of ionic liquid to alcohol was 1∶6, the ratio of the total volume of the extracted solvent to the mass of the medicinal material was 50∶1, the temperature was 40 ℃, and the ultrasonic time was 1 h. The extraction rate was (15.8±0.9)% under the optimal conditions, which was significantly increased compared to the conventional extraction rate of 5.14%. CONCLUSION It is feasible to extract flavonoids from Euphorbia lunulata Bge by using ionic liquid as solvent. Flavonoid extraction rate is not positively correlated with the carbon chain length of the ionic liquid parent nucleus. |
