| titleOfInvention | A kind of method that general flavone is extracted from Desmodium styracifolium |
| abstract | The invention discloses a kind of method that general flavone is extracted from Desmodium styracifolium, comprise the steps:Comprise the following steps：1) Desmodium styracifolium is cleaned up, dried, crushed with pulverizer, sieved；2) Subcritical Water Extraction：The raw material handled well is placed in extraction kettle, add the hydroxyethyl cellulose equivalent to the parts by weight of raw material 0.001, deionized deoxygenated water is injected in kettle, 150 250 DEG C of extraction temperature, the 10Mpa of pressure 8, the 1.0h of extraction time 0.5, Desmodium styracifolium is extracted, extraction terminates, pressure release, extract flows into collecting tank and is cooled to room temperature, obtains extract；3) purify：The extract that step 2) is obtained concentrates, and carries out column chromatography by macroreticular resin, 50%v/v ethanol elution, obtains eluent, concentrate, dries, obtain finished product. |
