Abstract:
OBJECTIVETo establish a method for determination of chlorogenic acid, caffeic acid, caffeoylquinic acid and ScuteIlarin in Dengzhan Xixin injection.
METHODThe HPLC method was carried out on Agilent Zorbax SB-C18 column (150 mm x 4. 6 mm, 5 pim) evaluated with acetonitrile-0.1% formic acid as mobile phase, gradient elution; the flow rate was 1.0 mL x min(-1); the temperatue of column was at 35 degrees C; the detection wavelength was at 335 nm for UV detection.
RESULTThe calibration curves were linear in the range of 0.025 to 0.800 microg (r = 0.9990) for chlorogenic acid, 0.027 to 0.850 microg (r = 0.9999) for caffeic acid, 0.062 to 1.978 microg (r = 0.9997) for caffeoylquinic acid and 0.118 to 3.770 microg (r = 0.9999) for scutellarin,respectilely. The average recoveries were 97.19% with RSD 1.16%; 100.45% with RSD 1.16%; 97.32% with RSD 1.43% and 103.81% with RSD 0.70%, respectively.
CONCLUSIONThe assay demonstrated that the method was simple, it had adequate accuracy and selectivity to quantify the four active components in Dengzhan Xixin injection.
