Determination of Pericarpium Papaveris (Yingsuqiao)in Bottom Material of Chafing Dish by High Performance Liquid Chromatography (HPLC)
火锅底料中罂粟壳的高效液相色谱法测定

Morphine, codeine and papaverine in bottom material of chafing dish were determined by HPLC.The conditions were as follows: C18 column, mobile phase V(CH3OH): V(25 mmol/L KH2PO4)= 90: 10,the flow rate 1 mL/min and the wavelength 254 um. These three compounds were entirely separated. The blank and positive comtrasts were being done simultaneously. The detection limit was 0. 1 mg/L. The experiment showed that this method is sensiuve, accurate and reliable.
