[Separation and purification of total flavones from Herba Epimedii by macroporous adsorption resin with the help of ultrasonic extraction].

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.
