Objective: To investigate the optimal separation of the total flavones from Herba Epimedii by macroporous adsorption resin.
Method: Nine types of macroporous adsorption were evaluated for separating efficiency by measuring the adsorption ratio, eluting ratio of total flavones.
Result: The D-101 macroporous adsorption resin had the best separating efficiency. After enrichment and purification with it, the product purity of total flavones was up to 63.8%.
Conclusion: This method is simple, feasible and fit for industry production.
