Objective:To establish a method for determination of total phenols from Phyllanthus urinaria in different locations. Method:Total phenols was determined by UV-Vis spectrophotometer with corilagin as reference substance and FeCl3-K3[Fe(CN)6] as chromogenic agent
the detection wavelength was at 744 nm. Result:A good linear relationship of corilagin was achieved in the range of 0.604-3.02 mg·L-1 (r=0.999 1)
the average recovery was 99.79% with RSD of 2.72%(n=6).The content of total phenols from P. urinaria in different locations was different from 5.00% to 12.16%. Conclusion:This established method was simple
accurate and stable which was suitable for determination the content of total phenols from P. urinaria.
