摘要
目的:从扁蓄中提取总黄酮并测定其含量.方法:选择乙醇为溶剂,用超声波技术从扁蓄中提取黄酮类物质,并对所提取的黄酮类物质进行验证,用分光光度法测定含量.结果:测得样品中总黄酮的平均含量为1.88%,平均回收率为100.95%.结论:运用超声波法从扁蓄中可以提取出黄酮类物质,加快提取速度,提高提取效率.
Objective： The total flavanone were extracted were checked. Methods：Ethanol was selected as solvent, lygonum aviculare L with ultrasonic wave and Using spec from polygonum aviculare L and contents the total flavanone were extracted from potrophotome try to extract and check the flavanone of polygonum aviculare L. Results： Measure sample in average content of the total flavonoid is 1.88%, Average recovery rate is 100.95%. Conclusion： Using ultrasonic wave can speed up the velocity of reaction and improve extract efficiency.
