AIM:
To apply Differential Scanning Calorimetry(DSC) identifying powder aqueous extracts and alcohol extracts of Radix et Rhizoma Salviae miltiorrhizae,Radix et Rhizoma Glycyrrhizae and Radix Paeonia rubra.METHODS:
?-Al_2O_3 was taken as the reference substance and under static state air condition,with the determination of the measuring range、the heating rate and temperature range of each herb or its extracts,the herbs were(identified) by comparing the characteristics and the peak profiles of their chromatography.RESULTS:
There were the tiny differences in DSC chromatography among powder,aqueous extracts and alcohol extracts,DSC chromatography of the same herbs from two different areas were very close to each other.CONCLUSION:
With great advantages of DSC method,such as very small amount of drugs,solvent-free.It is easy,quick and convenient to apply chromatography analyses.
