Abstract:
AIM:To simultaneously determine jatrorrhizine hydrochloride,palmatine hydrochloride,berberine hydrochloride、 evodiamine and rutaecarpine in Zuojin Pill(Rhizoma Coptidis,Fructus Evodiae).METHODS:A RP-HPLC method was established with gradient elution and an agilent C_ 18 column(250 mm?4.6 mm,5 ?m)was used.The mobile phase A was acetonitrile and the mobile phase B was water with 0.3% phosphoric acid-triethylamine.The detective wavelength was at 225 nm.RESULTS:Jatrorrhizine hydrochloride had a good linearity in the range of 0.013-0.065 ?g.The average recovery was 103.1% with RSD of 1.1%.Palmatine hydrochloride had a good linearity in the range of 0.013-0.102 ?g.The average recovery was 99.8% with RSD of 1.9%.Berberine hydrochloride had a good linearity in the range of 0.063-0.317 ?g.The average recovery was 99.8% with RSD of 1.4%.Evodiamine had a good linearity in the range of 0.001-0.007 ?g.The averoge recovery was 100.5% with RSD of 1.5%.Rutaecarpine had a good linearity in the range of 0.002-0.010 ?g.The average recovery was 98.9% with RSD of 1.9%.CONCLUSION:This method is simple,accurate and reproducible.It can be used to determine jatrorrhizine hydrochloride、 palmatine hydrochloride、 berberine hydrochloride、 evodiamine and rutaecarpine together with the same chromatogram condition.
