RESUMO
OBJECTIVE:To establish a method for qualitative identification of Shenjin huoxue mixture.METHODS:Ly-copodii japonicum,Paeonia lactiflora,Dipsacus asperoides and Radix et Rhizoma Glycyrrhizae in the preparation were identified by TLC.RESULTS:At the corresponding positions,the color of TLC spots of Paeonia lactiflora,Dipsacus asperoides and Radix et Rhizoma Glycyrrhizae in the test samples and in reference substances were identical.There was no interference form negative control.But no characteristic spots of Lycopodii japonicum in the sample were noted.CONCLUSION:The established TLC identification method of Paeonia lactiflora,Dipsacus asperoides and Radix et Rhizoma Glycyrrhizae is reproducible,specific,reliable and suitable for the quality control of Shenjin huoxue mixture.The absence of characteristic TLC spots of Lycopodii japonicum in the sample is suggestive of the necessity of improving the production technology of Shenjin huoxue mixture.
