ABSTRACT
OBJECTIVE:
To establish a method for the contents determination of gallic acid,naringin,hesperidin,neohesperi-din and baicalin in Qinghou liyan granule.METHODS:
UPLC was performed on the column of ACQUITY UPLC BEH C18 with mobile phase of acetonitrile- 0.1% phosphoric acid(gradient elution)at a flow rate of 0.40 ml/min,detection wavelength was 280 nm,column temperature was 30 ℃,and injection volume was 1 μl.RESULTS:
The linear range was 0.048-0.480 μg for gallic ac-id(r=0.999 3),0.012-0.120 μg for naringin(r=0.999 9),0.016-0.160 μg for hesperidin(r=0.999 8),0.022-0.220 μg for neo-hesperidin(r=0.999 9)and 0.072-0.720 μg for baicalin(r=0.999 2);limit of quantitation was 2.4,1.6,1.8,1.8,1.6 ng,limit of detection was 7.5,5.0,5.6,5.6,5.0 ng;RSDs of precision,stability and reproducibility tests were no lower than 3.0%;recover-ies were 96.64%-102.02%(RSD=2.00%,n=6),95.86%-102.56%(RSD=2.86%,n=6),97.24%-102.54%(RSD=2.10%,n=6),97.44%-102.60%(RSD=2.40%,n=6)and 96.91%-103.13%(RSD=2.62%,n=6).CONCLUSIONS:
The method is rapid and accurate,and can be used for the simultaneous determination of gallic acid,naringin,hesperidin,neohesperidin and baicalin in Qinghou liyan granule.
