Quantitative determination of flavonoids of pickles by HPLC with fluorescence detector

Quantitative determination of morin,quercetin,kaempferol and isorhamnetin of pickles with high performance liquid chromatography(HPLC) was established.The calibration curves were linear in the ranges of 0.25mg/L~8mg/L,0.25mg/L~8mg/L,0.25mg/L~8mg/L,and 0.25mg/L~ 8mg/L for morin,quercetin,kaempferol and isorhamnetin,respectively,and the correlation coefficients(r) were 0.9993,0.9998,0.9993 and 0.9999,respectively.There average recoveries were 89.5%~102.3%.
