Abstract:
OBJECTIVE To establish an HPLC method for determination of chlorogenic acid, mangiferin and hesperidin in Yinhua Mangguo tablets. METHODS Waters SunFire
TM C
18(4.6 mm×150 mm, 5 μm) column was used. The mobile phase was methanol-water containing 0.2% phosphoric acid with gradient elution mode at the flow rate of 1.0 mL·min
-1; the detection wavelength was 327 nm(0-10 min) for chlorogenic acid, 258 nm(10-20 min) for mangiferin, 283 nm(20-40 min) for hesperidin. RESULTS Chlorogenic acid had a good linearity in the range of 0.140-2.516 μg, the average recovery was 99.4% with RSD of 1.2% (n=9). mangiferin had a good linearity in the range of 0.042-0.761 μg, the average recovery was 99.9% with RSD of 1.4% (n=9). hesperidin had a good linearity in the range of 0.076-1.361 μg, the average recovery was 99.9% with RSD of 0.7%(n=9). CONCLUSION The method is simple, accurate and reproducible. It can be used to determine chlorogenic acid, mangiferin and hesperidin in Yinhua Mangguo tablets.
