Objective To establish an HPLC method for the determination of diester-type and lactone-type alkaloids in Bangga (a Tibetan traditional medicine) .Methods The column was Phenomenex luna C18 (250 mm × 4 .6 mm ,5 μm) ,and the flow rate was 1 .0 mL · min-1 .The diester-type mobile phase was A acetonitrile-tetrahydrofuran (25∶15) ,B 0 .1 mol · L -1 ammonium acetate solution (add 0 .5 mL glacial acetic acid per 1 000 mL) ,gradient elution ,the detection wavelength was 235 nm ,and the column temperature was at room temperature .The lactone-type mobile phase was methanol-water-chloroform-triethylamine (70∶30∶2∶0 .1) .The flow rate was 1 .0 mL · min-1 ,the detection wavelength was 230 nm ,and the column temperature was at 35 ℃ .Re-sults There is no double that ester alkaloids such as aconitine ,new aconitine ,and hypaconitine exist in Bangga .The linearity range of atisine was 2 .024-20 .24μg ,Y=1 .918 × 104 X-678(r=0 .999 9) ,and the average recovery was 97 .3% ,RSD=0 .9% ;The lin-earity range of hetisine was 2 .008-20 .08 μg ,Y=1 .602 × 104 X -215(r=0 .999 9) ,and the average recovery was 98 .6% ,RSD=1 .4% .Conclusion The method is accurate ,reliable and specific .It could be used for the quality control of Bangga .
