摘要
影响蜂胶总黄酮提取效率的主要因素是提取时间,其次是乙醇浓度,提取温度和料液比对提取效率几乎无影响;超声波提取具有短时高效的优点,适合于蜂胶总黄酮的提取;正交试验表明,超声条件下蜂胶总黄酮的最佳提取工艺是30℃,50min,95%乙醇,料液比1:30,此条件下测得总黄酮百分含量为6.39%。
The main factors affecting the content of total flavones extracted from propolis was the extraction time, the ethanol concentration and the extraction temperature, while the material-liquid ratio had little to do with the extraction efficiency. Ultrasonic wave extraction could short on the extraction time and increase the extraction efficiency, so could be considered for the extraction of total flavones from propolis. Orthogonal test results showed that the optimum conditions were 30℃、50min、95% ethanol and material-liquid ratio 1:30. Under the conditions, the yield of total flavones from propolis was 6.39%.
