ABSTRACT
OBJECTIVE:To establish the method for determining the contents of protocatechuic acid,rutin,gallic acid and kaempferol in Uygur medicine Capparis spinosa. METHODS:HPLC was performed on the column of Agilent C18 with the mobile phase of acetonitrile-0.1% phosphoric acid solution(7∶93,V/V)at the flow rate of 1.0 ml/min,the detection wavelength was 327 nm,column temperature was 30 ℃ and volume was 10 μl. RESULTS:The linear range was 0.260 0-50.0 μg for protocatechuic ac-id(r=0.995 6),3.109 0-102.0 μg for rutin(r=0.999 9),1.018 0-40.0 μg for gallic acid (r=0.998 9) and 0.063 0-36.0 μg for kaempferol(r=0.998 8);RSDs of precision,stability and reproducibility tests were all no more than 1.20%;average recoveries were respectively 101.51%(RSD=1.85%,n=6),99.70%(RSD=1.23%,n=6),98.28%(RSD=1.86%,n=6) and 100.97%(RSD=1.74%,n=6). CONCLUSIONS:The method is specific,and can fast and accurately determine the contents of protocate-chuic acid,rutin,gallic acid and kaempferol in Uygur medicine C. spinosa.
