Abstract:
OBJECTIVETo optimize the extraction conditions of Dandelions (Taraxacum Weber).
METHODUsing the uniform design, the content of total flavonoids and quercetin were detected to investigate the extraction process of Dandelions.
RESULTThe 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.
CONCLUSIONThe extraction ratio of total flavonoids and quercetin are higher according to the above extraction process.
