OBJECTIVE
To establish a HPCE method to determine the contents of alkalods in Rhizoma Coptidis.
METHODS
HPCE.
RESULTS
The constituents thus determined have good linearity and separation. The average recovery of coptisine, berberine, palmatine and jatrorrhizine was 98.28%, 98.38%, 97.78% and 98.89% respectively and RSD 0.86%, 1.12%, 1.06% and 1.11% respectively.
CONCLUSIONS
The method is convenient, rapid, accurate and practicable. The compatibility reduces the contents of alkaloids in Rhizoma Coptidis in different degrees.
