| titleOfInvention | Extraction method and application of flavanone skeleton compounds in saponins |
| abstract | The invention discloses a method for extracting flavanone skeleton compounds in saponins, which comprises the following steps: step 1, extracting saponins powder with ethanol heat reflux to obtain ethanol extract; step 2, adding water to the ethanol extract Dissolve and extract with petroleum ether and ethyl acetate to obtain petroleum ether extract and ethyl acetate extract; Step 3, separate the ethyl acetate extract by silica gel column chromatography to obtain fraction 1-15; Step 4, extract fraction 7 Silica gel column chromatography was carried out again to obtain compound 1, compound 2, compound 3 and compound 4; step 5, fraction 9 was subjected to silica gel column chromatography to obtain compound 5 and compound 6. The flavanone skeleton compound extracted and separated by the present invention has good anti-hepatoma cell activity, and provides a new scientific basis for further improving the medicinal value of saponins. |
