Abstract:
OBJECTIVE:To establish a method for the simultaneous determination of acetic acid and succinic acid in Banxia syrup. METHODS:RP-HPLC was performed on the column of GL InterSustain-C18 with mobile phase of 0.03 mol/L ammonium di-hydrogen phosphate buffer solution(pH2.0)-methanol(gradient elution)at a flow rate of 0.8 ml/min,the detection wavelength was 210 nm,column temperature was 30 ℃,injection volume was 10 μl. RESULTS:The linear range was 0.020 98-0.209 8 μg/ml for acetic acid(0.999 9)and 12.04-120.4 μg/ml for succinic acid(r=0.999 9);limits of quantification were 0.15,18.24 ng,limits of detection were 0.045, 5.53 ng;RSDs of precision, stability and reproducibility tests were lower than 2%;recoveries were 97.45%-101.68%(RSD=1.39%,n=9) and 98.31%-101.08%(RSD=1.01%,n=9). CONCLUSIONS:The method is accurate and rapid,and suitable for the simultaneous determination of acetic acid and succinic acid in Banxia syrup.
