摘 要:Objective To explore the optimum condition for complex enzyme-assisted extraction of galanthamine from Lycoris aurea by L_9(3~4) orthogonal array design and separation effect of cation exchange resin on galanthamine. Methods Cellulase and pectinase solution was used as the extraction solvent. The effects of p H value of enzyme, amount of complex enzyme, dissociation time, and enzymatic hydrolysis temperature on the extraction results were investigated. Results The optimal conditions were obtained as follows: ratio of solid to liquid(g:mL) 1:10, pH value 4.5, amount of complex enzymes 4%, enzymatic hydrolysis temperature 50oC, and reaction time 2.0 h. Under these conditions, the extraction yield of galanthamine was 0.0294%. In addition, D-001 cation exchange resin was selected for separation of galanthamine. The separation conditions were that adsorption flow rate was 3 BV/h with reagent of pH2 and the desorption flow rate was 3 BV/h with 70% ethanol solution containing 1.5 mol/L ammonia. After separation, the content of galanthamine was increased to 12.31%. Conclusion The results provide a reference for industrial production of galanthamine.Objective To explore the optimum condition for complex enzyme-assisted extraction of galanthamine from Lycoris aurea by L_9(3~4) orthogonal array design and separation effect of cation exchange resin on galanthamine.
