title: [Determination of protocatechualdehyde in yu xue bi granula].
abstract: The content of Protocatechualdehyde in YuXueBi granula was determined by HPLC. The chromatographic column was packed with ODS-2 (particle size 5 microns). The mobile phase was MeOH-H2O-H3PO4(17:83:0.003) adjusted to pH 3 with N(C2H5)3. The detection wavelength was 280 nm. The velocity of flow was 1.0 ml/min. The average recovery rate was 96.14%, RSD was 1.16%. The method was simple and stable.
