[Quality research on Epimedium cut crude drug processed with oil].
OBJECTIVE
To study internal quality of 14 batches Epimedium cut crude drug processed with oil, and to provide informations for quality specification in Chinese Pharmacopeia of 2010 edition.


METHODS
14 batches Epimedium cut crude drug processed with oil were investigated impurity, moisture content, total ash, acid-insoluble ash, extractum and assaying to analyze and evaluate their quality condition.


RESULTS
It is suggested that, in Epimedium cut crude drug processed with oil, the moisture content should not pass 8.0%, total ash should not pass 8.0%, acid-insoluble ash should not pass 2.0%, extractum content should not lower than 12.0%, total flavonoids content should not lower than 5.0%, icariin content should not lower than 0.6%, and Baohuoside I content should not lower than 0.1%.


CONCLUSIONS
Quality evaluation system of Epimedium cut crude drug processed with oil has been constructed initially, it will offer scientific basis for instituting quality specification in Chinese Pharmacopeia of 2010 edition.
