| titleOfInvention | The method of quercetin derivative is extracted from Camellia Leaves |
| abstract | The method that the present invention provides a kind of to extract quercetin derivative from Camellia Leaves.Method: Camellia Leaves are extracted；Using D101 as chromatographic column filler, crude extract is eluted with 75-85% ethanol solution；Last eluent is subjected to silica gel column chromatography separation, merges the fraction section containing Quercetin -3- rhamnoside, Quercetin Glucoside (or galactoside), using DAC chromatography post separation, collects Quercetin -3- rhamnoside fraction；Merge the fraction section for containing Quercetin Glucoside (or galactoside) simultaneously, is named as the second sequence component；Silica gel column chromatography is carried out to the second sequence component, merges the fraction section for containing Quercetin Glucoside (or galactoside), then carry out semi-preparative liquid chromatography separation, collects the fraction of Quercetin Glucoside (or galactoside).The present invention has successfully extracted the derivative of three kinds of Quercetins from Camellia Leaves simultaneously for the first time, and high income, product purity are high. |
