Objective To establish an HPLC method for separation and determination of the alkaloids in Rhizoma Coptidis. Methods HPLC system consisted of C
18
column (3.9 mm×300 mm
10 μm)
mobile phase was composed of acetonitrile solution of potassium phosphate (0.05 mol/L
40∶60
with 0.015 mol/L SDS)
and the detection wavelength was 345 nm. Results Five kinds of berberine-type alkaloids which are jatrorrhizine
epiberberine
coptisine
palmatine and berberine could be separated completely. Conclusion HPLC is of high sensitivity and good reproducibility. It can be used for quality control of drug and Chinese crude drug containing alkaloids.
