Abstract:
Objective To explore a quick and simple method to identify ginseng medicinal materials. Methods Twenty types of ginseng medicinal materials were collected. The effects of two important factors:temperature and heating rate on differential scanning calorimetry (DSC) were investigated. The DSC features were used to quickly identify Radix et Rhizoma Notoginseng, Radix et Rhizoma Ginseng, Radix Panacis Quinquefolii and Panna ginseng C.A.Mey. Results The optimal experimental conditions for rapid identification of Radix et Rhizoma Notoginseng, Radix et Rhizoma Ginseng, Radix Panacis Quinquefolii and Panna ginseng C.A.Mey by DSC were determined: temperature range 30-400 ℃, heating rate 30 ℃/min. Under these conditions, the characteristic peak temperature and thermal enthalpy value can be used to distinguish four kinds of ginseng. Conclusions The experiment shows that the DSC method has the advantages of simple operation, rapid measurement, good reproducibility, easy analysis of the spectrum and less sample consumption. It is a new method for quickly identifying Chinese medicinal materials of ginseng genus.
