Objective To compare the chemical composition change in Paeonia lactiflora Pall. of different storage time.Methods Paeonia lactiflora Pall.of different storage time were determined by HPLC method with paeoniflorin,paeoniflorin sulfite ester,albiflorin and gallic acid as the standards.Results The contents change of paeoniflorin,paeoniflorin sulfite ester did not have obvious correlation `with the storage time,the content of albiflorin gradually decreased with storage period,and the content of gallic acid did not have significant change.Conclusions Paeonia lactiflora Pall.stores time is long,but sulphur fumigation will greatly reduce the content of paeoniflorin.
