| titleOfInvention | Separation method for dermatophagoides farinae allergy resistant active substance in propolis |
| abstract | The present invention provides a separation method for dermatophagoides farinae allergy resistant active substance in propolis. The method comprises steps of: first, extracting the propolis with an ethanol solvent; second, conducting solid-liquid separation and rotary evaporation to remove ethanol, so as to obtain an extraction cream of dermatophagoides farinae allergy resistant active substance in propolis. According to the method, the extraction cream is further separated by column chromatography and thin layer chromatography to obtain active components. The method also comprises chemical structure identification on the active components of kaempferol and / or chrysin. The present invention provides a method for separating natural active substances from propolis and novel application of the active substances in resistance of dermatophagoides farinae allergy. The invention not only provides an efficient method and system for deep development and utilization of propolis, but also provides a new way for prophylaxis and treatment of dermatophagoides farinae allergen induced diseases. |
