| Abstract: | OBJECTIVE The content of quercetin in the fructus polygoni orientalis was determinated by spectrophotometry. METHODS The detection wavelength was set at 370 nm and temperature at 25 ℃. RESULTS The method was liner within the range of 0.004 0～ 0.011 9 mg/L r=0.999 2 .The average recovery of assay was 96.55% and RSD was 0.78%. CONCLUSION The method appears to be simple,highly accurate and can be used for the determination of the querceti content in fructus polygoni orientalis. |
