    摘要:

    利用微波辅助萃取法提取蜂胶中的黄酮类化合物,考察了微波提取条件(溶剂浓度、微波功率、提取时间、料液比)对蜂胶中黄酮提取率的影响,采用分光光度法测定提取液中黄酮的含量。结果表明:乙醇浓度为80%,微波提取功率为80 W,提取时间为1.5 min,料液比为1:4时,提取效果最佳。微波辅助法与传统提取法相比,具有提取效率高,时间短,节省溶剂用量等特点。

    Abstract:

    Microwave-assisted extraction (MSE) of total flavones from propolis was studied in this paper. The influences of some factors, including ethanol content, microwave irradiation power, the extraction time and the solid-liquid ratio, on the extraction yield of those compounds were determined. The extracts were analyzed by spectrophotometer. Results indicated that the optimal extraction solvent, irradiation power¸ extraction time and the solid-liquid ratio were ethanol, 80%, 80 W, 1.5 min and 1:4, under which the highest extraction yield was obtained. Compared with traditional extraction methods, MSE was better for the extraction of total flavones from propolis due to the shorter extraction time and higher yield.
