Objective: To establish the HPLC specific chromatograms of Phellodendri Chinensis Cortex decoction pieces and charred Phellodendri Chinensis Cortex decoction pieces
and to study on the change law of HPLC specific chromatograms of Phellodendri Chinensis Cortex before and after being processed. Method: HPLC was employed with the ZORBAX SB-C18 column
acetonitrile-0.05 mol·L-1 potassium dihydrogen phosphate solution (phosphoric acid regulated pH to 3.4) was employed as a mobile phase in gradient elution
the detection wavelength was 215 nm
column temperature was at 35℃ and the flow rate was 1.0 mL·min-1. Result: Eleven batches of Phellodendri Chinensis Cortex decoction pieces were marked with sixteen characteristic peaks
and chlorogenic acid
cryptochlorogenic acid
phellodendrine
magnoflorine
jatrorrhizine hydrochloride
palmatine hydrochloride
berberine hydrochloride
obaculatone and obakunone were assigned.Based on the analysis of characteristic peaks
only three common peaks were detected in charred Phellodendri Chinensis Cortex decoction pieces
and the area of these peaks was quite different;in addition
two feature peaks were identified
with the relative high proportion of the characteristic peak being analyzed and verified to be berberrabine
the product of the heat decomposition of berberine hydrochloride. Conclusion: There are significant differences in the specific chromatograms of Phellodendri Chinensis Cortex decoction pieces before and after being processed.The method is accurate and reproducible
which can provide the basis for the quality standard of Phellodendri Chinensis Cortex decoction pieces and charred Phellodendri Chinensis Cortex decoction pieces.
