蜂胶黄酮类化合物提取工艺参数优化

基于合理的实验工艺条件的选择和实验设计,利用了RSA响应面分析方法对以乙醇溶液为夹带剂,利用超临界流体CO2萃取蜂胶黄酮类化合物的工艺参数进行优化。结果表明:各响应因子萃取压力、乙醇浓度和固液比的最佳工艺参数分别为:25MPa、95%和6:1, 同时丰富了蜂胶类黄酮化合物的超临界流体CO萃取工艺优化设计。

Based on sensible selection of experimental processing conditions and design, response surface analysis methodwas used to optimize processing parameters of the extraction of Propolis flavonoids, which was carried on with the technologyof supercritical fluid extraction with alcohol as modifier. The results showed that the optimal processing parameter of extrac-tion pressure, alcohol concentration and solid-liquid ratio was at 25 MPa, 95% and 6: 1 respectively. The result developed theextraction technology of Propolis flavonoids with supercritical fluid extraction.
