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.
