| Abstract: | An experimental method was established to detect 5-hydroxy tryptamine(5-HT) in the blood of Pacific white leg shrimp Litopenaeus vannamei using high performance liquid chromatography(HPLC).After the protein in the samples was removed by high chlorine acid,the samples were detected by HPLC method using Purospher STAR RP-18(150 mm×4.6 mm,5 μm) column to separate,under the condition of mobile phases including potassium dehydrogenate phosphate of 0.1 mol/L(pH 3.0),methanol and acetonitrile(70∶5∶25).The flow rate was maintained at 0.8 mL/min,and column temperature of 25 ℃,and the injection volume was 10 μL.The fluorescence detector under the condition of excitation wavelength 280 nm and emission wavelength 340 nm was utilized for testing.The results showed that the linear range of this method was ranged from 0.5 to 100.0 μg/L and the linear correlation coefficient r2 was 0.9982.,with average recovery of 87.9%. |
