| 摘 要： | 目的研究黄芩中黄芩苷的优化工艺条件,为进一步开发应用奠定基础。方法通过单因素实验考察了煎煮时间、加水倍量、煎煮次数3个因素对黄芩苷含量的影响,并在此基础上,通过Box-Behnken中心组合实验设计和响应面分析优化黄芩中黄芩苷提取工艺,以黄芩苷含量为评价指标进行分析。结果黄芩苷的最佳提取工艺条件为煎煮时间68.37 min,加水倍量10.46倍,煎煮3次,黄芩中黄芩苷含量较高,达到8.53%。结论获得的最佳提取工艺稳定可行,为进一步开发应用奠定基础。 |

| Abstract: | Objective To optimize extracting technology of baicalin distilled from scutellaria and lay an foundation for further development.Methods To observe the influence of the decocting time,the water addition and decocting frequency as the independent variables on baicalin content.Based on the observation,the experiment was optimized the extracting technology of baicalin distilled from scutellaria by Box-Behnken experimental design combined with response surface methodology.The response variable was the content of baicalin.Results The optimum extraction condition were to decoct for 2 times with 10.16 times of water and each time for 68.37 min,the content of baicalin is higher than other condition.The dried extraction yield was 8.53 %.Conclusion The experiment was get the best way to optimize the extraction technique,and laid the foundation for the further development and application. |
