Abstract:
AIM:To research the chemical modification from berberine hydrochloride to berberrubine in Cortex Phellodendri before and after processing.METHODS:Berberrubine was isolated by column chromatography and the contents of berberine hydrochloride and berberrubine in different processed Cortex Phellodendri were determined by HPLC.RESULTS:With increacing processing temperature and time,part of berberine hydrochloride became berberrubine in processed Cortex Phellodendrin,and berberrubine content decreased under the condition of high temperature operation or overtime processing.CONCLUSION:The experimental data shows that the processed Cortex phellodendri has the maximum average content of berberrubine as processing temperature is maintained as 180 ?C for 40 min.
