ABSTRACT
OBJECTIVE:
To develop a method for the simultaneous determination of 5 components in Shuganning injections.METHODS:
HPLC method was adopted. The determination was performed on Symmetry? C18 column with mobile phase consisted of methanol-0.4% phosphoric acid(gradient elution)at the flow rate of 1.0 mL/min. The detection wavlengths were set at 238 nm (geniposide,baicalin) and 327 nm (chlorogenic acid,baicalein,scutellarin). The column temperature was 30 ℃ and the sample size was 10 μL.RESULTS:
The linear ranges were 0.4062-26.0 μg/mL for chlorogenic acid(r=0.9999),2.5000-160.0 μg/mL for geniposide (r=0.9999),6.5620-420.0 μg/mL for baicalin (r=0.9999),0.3125-20.0 μg/mL for baicalein (r=0.9996), 0.5859-37.5 μg/mL for scutellarin (r=0.9998). The limits of quantify were no higher than 31.20 ng,limits of detection were no higher than 15.60 ng. RSDs of precision, stability and reproducibility tests were lower than 2.0% ;the recoveries were 97.72%-101.10%(RSD=1.21%,n=6),97.67%-102.40%(RSD=1.87%,n=6),97.64%-101.10%(RSD=1.31%,n=6), 96.45%-100.10%(RSD=1.47%,n=6),96.16%-101.10%(RSD=1.69%,n=6),respectively.CONCLUSIONS:
The method is simple,precise,stable and reproducible,and can be used for simultaneous determination of 5 components in Shuganning injection.
