Abstract

OBJECTIVE: To obtain the optimal conditions for separating the alkaloids from the extract of Radix of Zanthoxylum nitidum by selecting appropriate macroporous adsorption resins. METHOD: Eight types of macroporous adsorption were evaluated in separating efficiency with measuring the adsorption ratio and eluting ratio of Alkaloids as indexes. RESULT: The XDA-5 macroporous adsorption resin had the best separating efficiency. After enrichment and purification with it, the product purity and yield of alkaloids were up to 33.25% and 90.15%, respectively. CONCLUSION: This method is simple, feasible and fit for industry production.
