Abstract:Chemical fingerprints of Radix Paeoniae Rubra(RPR)from different places of origin were studied by chemical oscillation system of H2SO4-CH2(COOH)2-Ce2(SO4)3-KBrO3.Effects of various variables on the chemical oscillation system were studied.The optimal conditions were as follows:12 mL 3.0 mol/L sulfuric acid,6 mL 0.4 mol/L malonate,3 mL 0.005 mol/L cerium ammonium sulfate,3 mL 0.2 mol/L sodium bromate and 0.4 g RPR powder at 35 ℃.The results indicated that,under the optimal conditions,the chemical fingerprints of RPR from different places of origin(Bozhou,Heze,Chifeng and Hailaer) showed significantly different characteristics,such as the maximum potential,induction time and oscillation lifetime,etc.The results also indicated that the RPR from Bozhou had the shortest induction time(133.76 s),but the longest oscillation lifetime(554.89 s).The RPR from Hailaer had the longest induction time(214.17 s),but the shortest oscillation lifetime(only 237.11 s).The chemical fingerprints could be used to identify the origins of RPR.The method is simple,rapid and sensitive,and without need sample preparation.
Keywords:chemical fingerprint  chemical oscillation system  Radix Paeoniae Rubra  identify
