【摘要】 对以蜂胶为原料提取黄酮类化合物的工艺进行了研究。研究了溶剂与蜂胶的质量配比(液固比)、溶剂的质量分数、提取时间、提取温度对黄酮类化合物含量的影响。结果表明:在40℃下,当液固比为8:1,乙醇质量分数为80％,提取时间为6h时,所得产品中黄酮类化合物的质量分数达21．5％。工艺操作简单,经济适用, 含量高。更多还原

【Abstract】 The technology of extracting flavonoids from propolis was discussed. The factors affecting the yield were investigation. The results showed that 40 ℃, 8:1 of 80 % ethanol to propolis weight ratio, extract for 6h were optimal. The amount of flavonoids is 21.5 % under the optimum conditions. The process was simple and economic with higher practicability and efficiency.更多还原
