摘　　要：目的探讨差示扫描量热法快速鉴别4种人参属药材的可行性。方法收集20份人参属药材,以升温范围、升温速率为考察因素,优化差示扫描量热法的检测条件,利用差示扫描量热法特征图谱快速鉴别三七、人参、西洋参、高丽参4种人参属药材。结果确定了差示扫描量热法快速鉴定4种人参属药材的最佳试验条件:升温范围30~400 ℃;升温速率30 ℃/min;在该条件下通过特征峰温和热焓值可较好区分4种人参属药材。结论差示扫描量热法具有操作简便、测量快速、重现性好、谱图易解析和样品用量少等优点,可快速鉴别人参属中药材。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.
