| 摘 要： | 目的:优选黄芩中黄芩苷的浸取工艺。方法:采用正交设计试验,以黄芩苷浸取率为指标,对影响黄芩中黄芩苷浸取工艺的因素进行了考察,比较了乙醇回流法与水煎煮法、超声波法、半仿生法的黄芩苷浸取率。结果:在浸取温度为80℃,浸取时间为1 h,乙醇浓度为60%,搅拌速度为400 r/min时,黄芩苷的浸取率最高,达83.09%。同时,结果表明,乙醇回流法在黄芩苷的浸取中优于其它的方法。结论:醇提法浸取效率高,经济,浸取剂利于回收,适合工业化生产。

| Abstract: | OBJECTIVE: To optimize the extraction process of baicalin from Scutellaria Baicalensis Georgi with ethanol. METHODS: The extraction process of baicalin from Scutellaria Baicalensis Georgi was optimized with the aid of orthogonal experiments. RESULTS: 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%. CONCLUSION: 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. |
