Studg on Adsorption and Separation Properties of Total Flavones From Euphorbia Humifusa、Leaves of Flos Lonicerae and Chrysanthemum Morifolium by Macroporous Resins / 医学研究杂志

ABSTRACT

Objective In order to study the application of macroporous resins and so on to the purified active components of Euphorbia humifusa、Leaves of Flos Lonicerae、Chrysanthemum morifolium,adsorption and separation properties for 3 types of macroporous resins and polyamide were investigated.Methods The total flavone was used as the evaluating criteria,we selected suitable macroporous resins and studied optimum technological parameters of the adsorption and elution.Spectrophotometry was used for the determination of total flavone.Results The suitable macroporous resins which were used to the purified active components of traditional Chinese medicine were D101 and DA201 and DM301 for Euphorbia humifusa、DA201 for Leaves of Flos Lonicerae、D101 and DA201 and DM301 for Chrysanthemum morifolium,The concentration of the sample of Euphorbia humifusa for DA201 and D101 were 0.49～1.47 and 0.42～1.31 mg/ml.The concentration of the sample of Leaves of Flos Lonicerae for DA201 was 1.03～2.07 mg/ml.The concentration of the sample of Chrysanthemum morifolium for DA201 and D101 was 0.50～1.00 and 0.71～1.99 mg.ml.In the adsorption course,appeared leaking were 8 and 10、2、2 and 1 BV respectively.In the elution course,when the alcohol concentrations were 20%、30%、40% and 20%、30%、40%;10%、20%、30%;30%、40%、50% and 20%、30%、40%;respectively,the total flavone content in the elution solutions was higher.The influence of temperature to DA201 and D101 adsorpting total flavone for Euphorbia humifusa was not great.But the influence of temperature to DA201 and D101 adsorpting total flavone for Leaves of Flos Lonicerae and Chrysanthemum morifolium were certain degree.Conclusions It is obviously different to refine the total flavone active components of traditional Chinese medicine,while using 3 types of macroporous resins and polyamide.
