Abstract:
Objective To evaluate the performance of FL-1 macroporous absorption resin for absorption of total flavonoids from Psidium guajava leaf.Methods The concentration of total flavones in Psidium guajava leaf was determined by ultraviolet spectrophotometry and the absorption behavior of FL-1 macroporous adsorption resins to total flavones in Psidium guajava leaf was examined for the adsorption capacity and the volume of solution loaded.Results Optimal absorption of total flavonoids was achieved with the sample:total flavonoids concentration in the solution of 13.22 mg/mL,the ratio of total flavonoids concentration and macroporous adsorption resin was 1∶4,washing with 70% ethanol at the flow velocity of 2 BV/h.Conclusion FL-1 Macroporous absorption resin can be well applicable for enrichment of total flavonoids in Psidium guaijava leaf.
