Determination of paeonol and cinnamaldehyde in Jiarong Tablet by HPLC / 中成药

ABSTRACT

AIM: To establish an HPLC method of determining paeonol and cinnamaldehyde in Jiarong Tablet. METHODS: Column:Kromasil C_(18)(200 mm?4.6 mm I.D,5 ?m);mobile phase:MeOH-H_2O(65∶35);detection wavelength was at 288 nm;flow rate was 1.0 mL/min. RESULTS: The calibration curve showed a good linea-rity within the ranges of 0.003 6830.018 412 ?g for cinnamaldehyde,0.097 92-0.489 6 ?g for paeonol.(CONCLUSION:)The method is accurate and can be used for the quality control of Jiarong Tablet.
