摘要
以石榴皮为材料,选用不同方法提取石榴皮总黄酮,比较不同提取方法对石榴皮黄酮类物质的提取效果。分别采用热水浸提法、乙醇回流提取法、超声波辅助提取法来提取石榴皮总黄酮,采用分光光度法测定总黄酮含量,并计算得率。结果表明,超声波辅助提取法提取总黄酮得率最高,乙醇回流提取法次之,热水浸提法总黄酮得率最低。
To compare different extraction methods of flavones from the negranate skin. The yield of total flavones by the ultrasonic extraction is the highest, the second by the ethanol-extraction, the lowest by the water-extraction.
