摘　　要：蜂胶黄酮是蜂胶的主要活性成分,具有抗氧化、抗菌等多种功效。优化蜂胶黄酮的超声提取工艺,为蜂胶产品的开发与利用提供了理论依据。首先进行了单因素试验,研究超声功率、超声时间和乙醇浓度这三个因素分别对蜂胶黄酮提取得率的影响。在此基础上,再采用响应面法优化蜂胶黄酮的超声提取条件。研究结果表明,影响蜂胶黄酮提取得率的主次因素依次是超声时间、乙醇浓度和超声功率。当超声功率为150 W、超声时间为16 min、乙醇浓度为86%时,蜂胶黄酮提取得率实际最大可达到21.10%±0.075%(n=3)。经本实验分析可知,湖北孝感蜂胶属于蜂胶中的优等品。相比于其他超声提取蜂胶黄酮的方法,该实验的超声提取方法具有提取温度低、提取时间短的优势。Flavonoids are the main bioactive components in propolis,which exhibit a variety of physiological activities such as anti-oxidative and antibacterial effects.Optimization of ultrasonic extraction of propolis flavonoids will provide a theoretical basis for exploitation and utilization of propolis products.Firstly,single-factor experiments are carried out.The effects of three extraction parameters(ultrasonic power,extraction time and alcohol concentration)on extraction yield of propolis flavonoids are investigated.Secondly,based on the single-factor tests,the ultrasonic extraction conditions of flavonoids from propolis are optimized by using response surface methodology.The experimental results show that the order of factors affecting the extraction yield is extraction time,alcohol concentration and ultrasonic power.The maximum extraction yield of propolis is 21.10%±0.075%(n=3)while ultrasonic power is 150 W,extraction time is 16 min and alcohol concentration is 86%.According to the analysis of this experiment,it is found that the propolis from Xiaogan,Hubei is identified as premium grade product in propolis.Compared with other ultrasonic extraction methods of propolis flavonoids,the ultrasonic extraction method used in this study has the advantages of lower extraction temperature and shorter extraction time.
