[Purification technology of Rhizoma et Radix Notopterygii and Radix Angelicae Pubescentis in Fufang Xuelian dropping pills by macroporous resin].
OBJECTIVE
To study the purification technology of Rhizoma et Radix Notopterygii and Radix Angelicae Pubescentis in Fufang Xuelian dropping pills by macroporous resin.


METHODS
Taking osthole, isomperatorin as index ingredients, the type of resin sampling amount and elution solvent were decided, and the influence of sample concentration pH of sample and ratio of diameter to height of column to adsorption were studied.


RESULTS
HPD400A was chosen to purify, the suitable sampling ratio of resin volume to raw material was 1:2; pH 3.5 (crude drug) and ratio of diameter to height was 1:7; 95% ethanol of the elution solvent was satisfactory eluant for desorption.


CONCLUSIONS
HPD400A macroporous resin can be used to purify Rhizoma et Radix Notopterygii and Radix Angelicae Pubescentis.
