ABSTRACT
ObjectiveA method was proposed for the determination of the concent of total glucoside of peaony(TGP) fromPaeonia lactifloriaPall. by UV spectrophotometry.MethodsBased on the extract with 80% acidities alcohol, extracted by aether and n-butyl alcohol, TGP was obtained fromPaeonialactifloriaPall.. The determination was established with paeoniflorin which was the main component of TGP as a contrast by UV spectrophotometry at 230 nm.ResultsA good liner relationship between concentrationof paeoniflorin and its absorbance was obtained,and the liner range was between 0.040 2~0.201 1 mg/ml. The averagerecovery was 101.81%.ConclusionThis method is simple rapid and reliable. It could be used for the semi-quantitative determination of TGP of paeony in paeonialactifloria pall..
