| titleOfInvention | A kind of method simultaneously extracting icarin and the precious leaves of pulse plants glycosides I, II from Herba Epimedii |
| abstract | The invention discloses a kind of method simultaneously extracting icarin and the precious leaves of pulse plants glycosides I, II from Herba Epimedii, by Epimedium plant grinding and sieving net, add ethanolic soln, heating and refluxing extraction, filter and obtain liquor B, concentrating under reduced pressure reclaims ethanol and obtains primary extract; Gained primary extract purified water is extracted, adjusts PH, leave standstill, suction filtration, obtain icarin extract; Adopt macroporous adsorbent resin to carry out wash-out to icarin extract, carry out de-washing with ethanol, collect elutriant; In elutriant, add medical active carbon, reflux, cooling, filter and obtain liquor C; Liquor C is carried out separating-purifying and crystallization through simulated moving bed chromatography, obtains icarin crystal, and collect filtered liquid D; The drying of icarin crystal is obtained pure icarin finished product; In filtrate D, add tween, with glucuroide or cellulase degradation, the chromatographic column that enzymolysis solution is filled by macroporous resin mixing carries out separation and purification, obtains the product precious leaves of pulse plants glycosides I, II. |
