To optimize the extraction process of baicalin from Scutellaria Baicalensis Georgi with ethanol.
The extraction process of baicalin from Scutellaria Baicalensis Georgi was optimized with the aid of orthogonal experiments.
The optimal parameters were obtained as follows: extracting temperature, extracting time, ethanol concentration and mechanical stirring speed were 80 degrees C, 1 h, 60% and 400 r/min, respectively. The extracting rate of baicalin was 83.90%.
Comparing ethanol circumfluence, boiling water, ultrasonic wave and semi-bionic on extracting baicalin from Scutellaria baicalensis Georgi, the ethanol circumfluence extraction is better than other technological conditions on extracting baicalin.
优化乙醇提取黄芩中黄芩苷的工艺。
借助正交试验优化黄芩中黄芩苷的提取工艺。
获得的最佳参数如下：提取温度、提取时间、乙醇浓度和机械搅拌速度分别为80℃、1小时、60%和400转/分钟。黄芩苷的提取率为83.90%。
比较乙醇回流、沸水、超声波和半仿生法从黄芩中提取黄芩苷，乙醇回流提取法在提取黄芩苷方面优于其他工艺条件。
