Influencing factors of static adsorbing process of extract of Herba Artemisiae scopariae with macroporous resin / 中成药

ABSTRACT

AIM: To study the influencing factors of static adsorpting process of extract of Herba Artemisiae scopariae with macroporous resin,and determine the refinement process. METHODS: The absorbances and the adsorption quantity of caffeotannic acid were used as indexes,the adsorption effect of 9 kinds of macroporous resin and static adsorption curve of F resin;density and pH of the extract liquor were investigated by use of factorial experiment;HPLC fingerprint of extract of Herba Artemisiae scopariae were evaluated the adsorption effect.(RESULTS:) The adsorpting effect were different among types of macroporous resin,and the adsorpting equilibrium time was 6 h in the use of F resin;Density and pH of the extract liquor are important factors of adsorption;The experiment indicated that decreased liquor by this process were important factors of adsorption;The experiment indicated that this process decreased the yield of extract by 2.5%. CONCLUSION: The result can offer information about the determination of refinement process of extract of Herba Artemisiae scopariae with macroporous resin.
