| Abstract: | A determination method of total flavonoids in Cirri Reticulatae Pericarpiurn was established to control the quality of Cirri Reticulatae Pericarpium. Hesperidin was chosen as reference substance, and the total flavonoids were measured by ZrOC12 colorimetry with the wavelength of 312.5nm. A good linear relationship between the absorbance and the concentration was found within the concentration range of 0. 0044-0. 022mg/mL （r= 0. 9999）. The average recovery rate was 100.69 %, and RSD was 1.64% （n=6）. This simple method,with good stability and reproducibility, can be used to determine and evaluate the total flavonoids in Cirri Reticulatae Pericarpium. |
