OBJECTIVE
To optimize the extraction conditions of Dandelions (Taraxacum Weber).
METHOD
Using the uniform design, the content of total flavonoids and quercetin were detected to investigate the extraction process of Dandelions.
RESULT
The ethanol concentration and the ethanol volume in the uniform test impacted the test mostly. The best extraction process of Dandelions was obtained as following: 13 times of 85% ethanol as the solvent, extraction for 2 times and 1 h for each time.
CONCLUSION
The extraction ratio of total flavonoids and quercetin are higher according to the above extraction process.
目的
优化蒲公英（蒲公英属韦伯）的提取条件。
方法
采用均匀设计，检测总黄酮和槲皮素的含量以研究蒲公英的提取工艺。
结果
均匀试验中乙醇浓度和乙醇体积对试验影响最大。得出蒲公英的最佳提取工艺如下：以13倍量85%乙醇为溶剂，提取2次，每次1小时。
结论
按照上述提取工艺，总黄酮和槲皮素的提取率较高。
