摘要
将微波预处理技术应用在黄芩中黄芩苷的提取中,采用单因素试验法,考察润湿时间、乙醇用量、乙醇浓度、微波功率以及微波作用时间对黄芩苷得率的影响。确定优化的提取工艺参数为:润湿时间50min、乙醇用量14mL、乙醇浓度80%、微波功率800W、微波作用时间90s。结果表明微波预处理提取黄芩中的黄芩苷,具有提取得率高、提取时间短的特点。
Microwave pretreatment technique was used for extraction of baicalin in scutellaria baicalensis georgi. Its parameters,such as soaking time, quantity of ethanol, ethanol concentration, microwave power, microwave radiation time, were analyzed by single-factor tests. The optimum pretreatment conditions are soaking time 50 minutes, quantity of ethanol 14 mL, ethanol concentration 80 %, microwave power 800 W, microwave radiation time 90 seconds. The results show that microwave pretreatment method has high field of extraction and short time of extraction.
