| Abstract: | A method for determination of Bixin in food using ultra high performance liquid chromatography had been developed.The sample was extracted by acidified acetonitrile,cleaned up with hexane and determined by UPLC-UV.The separation column was used with Waters BEH C18（1.7μm,2.1×50mm）.The detection limit was 0.1mg/kg.The recovery ranged from 83.8% to 96.1% with five food samples,the relative standard deviation（RSD） was 0.6%~6.1%（n=6）.The good linearity was achieved in 0.1μg/mL ~2μg/mL with r=0.9999,the result was satisfactory. |
