| titleOfInvention | Method for simultaneously determining five flavones in Chinese herbal medicine or health product |
| abstract | The invention discloses a method for simultaneously measuring five flavones in Chinese herbal medicines or health products, which comprises the steps of extracting a dry solid medicinal material or health product sample by using methanol, using acetonitrile and 0.5% (v/v) phosphoric acid as mobile phases by using a high performance liquid chromatography, carrying out gradient elution after sample loading to obtain a chromatogram of puerarin, dihydromyricetin, rutin, quercetin and kaempferol with good separation degree, and calculating the content of the five flavones in the raw material according to the integral area of the characteristic peak of each flavone. The method is particularly suitable for rapidly detecting the identification and quantification of the flavone with large polarity difference in the health care products or the Chinese herbal medicines and evaluating the content of the drug effect substances. |
