Extraction and Analysis of Flavonoids from Seven Herbal Species of Potentillae from Anhui Province
The technological conditions of extraction and purification of flavonoids from Potentilla chinensis from Anhui Province were studied by using 4-factor and 4-level orthogonal test. The technological conditions of flavonoids from Potentilla chinensis purified with AB-8 macroporous resin were studied from the aspects of the optimum sample concentration, load volume, the concentration of ethanol elution solution and ethanol elution volume. And flavonoid was extracted from 7 herbal species of Potentillae from Anhui Province by using the optimized extraction conditions and flavonoid content in different species of Potentillae was measured by using colorimetry. Under the conditions of 70 ℃, the extraction effects were the best. The crude flavonoid content was 17.98%. After being purified with AB-8 macroporous absorption resin, the content of flavonoid in crude flavonoid powder was up to 33.30%.
