Determination of narigin and hesperidin in Juhong Pills by HPLC / 中成药

ABSTRACT

AIM: To establish the determination of narigin and hesperidin in Juhong Pills(Exocarpium, Citri Grandis, Pericarpium Citri Reticulatae, Radix Angelicae Sinensis, etc.). METHODS: The extraction was completed with ether. The Shim-pack ODS(?6.0mm?150mm) column was used with mobile phase of CH 3OH-CH 3COOH-H 2O(30∶4∶60). The detection wavelength was at 283nm. RESULTS: The linear range for narigin was 0.072～1.43?g, r=0.9999 and the linear range for hesperidin was 0.068～1.37?g, r=0.9999, respectively. Both the average recoveries were 99.3% and 99.4%, respectively. Both RSD were 0.6%(n=5). CONCLUSION: The method is simple and the result is reliable.
