ABSTRACT
OBJECTIVE:
To develop an HPLC method for content determination of protocatechualdehyde in Tong-jingkang oral liquid.METHODS:
Zorbax Eclipse XDB-C18(250 mm?4.6 mm,5 ?m) was used as chromatographic column with mobile phase consisted of methanol-water-formic acid(20∶79.5∶0.5) at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 280 nm and the temperature of column was kept at room temperature.RESULTS:
The linear range of protocatechualdehyde was 0.025~0.5 ?g(r=0.999 9) with an average recovery of 101.1%(RSD=2.29%,n=6).CONCLUSION:
The established method is simple,accurate and it is applicable for the quality control of Tongjingkang oral liquid.
