| titleOfInvention | The enzyme assisted extraction process of Quercetin 3-galactoside in a kind of Folium Acanthopanacis Senticosi |
| abstract | The invention discloses the enzyme assisted extraction process of Quercetin 3-galactoside in a kind of Folium Acanthopanacis Senticosi.Get Folium Acanthopanacis Senticosi meal, add the water of its quality 2-3 times amount, then add mass ratio (2-3): the cellulase of 1 and the mixture of polygalacturonase make it reach 0.2-0.3mg/ml, regulate pH to 4.0-5.0, be heated to 40-60 DEG C, enzymolysis 1.5-2h, be then warming up to 70-80 DEG C of deactivation; Add 90-95% ethanol, after immersion, seepage pressure effects, collects percolate, reclaims ethanol, obtains concentrated solution; Concentrated solution is added the water dilution of its quality 2-3 times amount, filter to obtain supernatant liquor; By macroporous adsorbent resin on supernatant liquor, after washing, 70-75% ethanol elution, collects elutriant, and reclaim ethanol, drying under reduced pressure, obtains concentrated powder; To concentrate reversed-phase resin column chromatography on powder, 20-30% ethanol elution, and collect elutriant, reclaim ethanol and obtain coarse crystallization, recrystallizing methanol obtains Quercetin 3-galactoside.The present invention take Folium Acanthopanacis Senticosi as raw material, and adopting enzyme assisted Extraction to follow the example of, is that solvent carries out wash-out with ethanol, environment friendly and pollution-free, easy to operate, reduces production cost. |
