Abstract: HLPC was applied to determination the three kinds of alkaloids including berberine, jatrorrhizine, palmatine in Mahonia stem (9 species, 17 samples) from different areas in Sichuan (including part area of Chongqing). The results show that:①the alkaloid contents of the Mahonia in Sichuan are generally high; ②total content of three kinds of alkaloids are stable in the same species, while every constituent fluctuates greatly according to habitats; ③berberine is playing a leading role in the constituents of the alkaloid; ④the species including M.taronensis Hand-Mazz, M.fortunei (LindL.).Feddle, M.eurybracteata, M.confusa Sprague and M.calamicaulis spare et Fish are excellent in content of berberine which is over 0.8%, so it is valuable to explore Mahonia genus in Sichuan.
