【摘要】 采用微波技术，对蜂胶黄酮的提取工艺进行了改进性研究。选择醇浓度、微波处理时间、恒温天数三个影响因素，进行正交设计。优选出微波提敢的最佳工艺：乙醇浓度为８０％，微波处理时间为１５分钟，恒温天数为２天。提取时间较常规方法缩短一半，提取率有很大提高。更多还原

【Abstract】 A study has been done about the improvement of the flavonoid diffused technology. With some different concentraion of alcohol, microwave time, and diffused time orthogonal test was carried out. Choose the best diffusing test design, that is the concentration of alcohol was 80%, the microwave time was 15 minutes, and the diffused time was 2 days. So the application of microwave technique in the Chinsese medicinal material diffu- sion is a new method. The amount of flavonoid diffused from propolis is larger than its traditional method.更多还原
