摘　　要：[目的]应用热分析法鉴别彝族植物药。[方法]用差热-热重分析(DTA-TGA)和差示扫描量热法(DSC)对瓦布友等彝族植物药进行测定,根据图谱峰形和特征进行比较鉴别。[结果]不同样品的DTA的放热峰特征明显,峰顶温度和峰数量不同,同一样品不同组织部位的DTA放热峰不同,不同样品的DSC的特征峰更加明显。[结论]热分析法是彝族植物药鉴别的一种有效鉴别方法,DTA曲线的特征峰可作为鉴别的佐证,DSC曲线的特征峰可作为进一步鉴别的佐证。[ Objective] The aim was to investigate the Yi nationality plant medicine by thermal analysis technique. [ Method] Wabuyou and other Yi nationality plant medicine were determined by DTA-TGA and DSC in the static air, the identification was compared according to peak shape and characteristics of map. [ Result ] The peak＇ s temperature and numbers of DTA curves were obvious among different kinds of samples. The peak of DTA curves is different among different tissue of the same sample. The characteristic peak of DSC curve is more obvious among different samples. [ Conclusion] The thermal analysis technique is a kind of effective identification method. The characteristic peak of DTA can be used to identify Yi national plant medicine. The characteristic peak of DSC can be used to further identify Yi national plant medicine.
