摘　　要：目的研究受热对一枝黄花干粉的影响。方法用差示扫描量热法（DSC）和热重-微分热重法（TG-DTG）对一枝黄花干粉进行了热分析研究。结果加热到118℃时质量损失约6.80%,118-387℃时质量损失约50.57%,388-682℃时质量损失约11.79%,到972℃时质量仅余约14%,在277℃,859℃分别有两个放热峰。结论一枝黄花干粉宜贮存在低于40℃的环境中,加工、炮制时,温度宜控制在210℃以下。Objective To understand the influence of heating dried Soldago decurrens Lout power. Methods The thermal properties of dried Soldago Decurrens Lour power was studied by DSC method and TG - DTG method in the static air. Results Heated up to 118℃ ,a mass loss of 6.8% was observed. From 118 - 387℃ , a mass loss of 50.57% was observed. From 388 -682℃ ,a mass loss of 11.79% was observed. Up to 972℃ ,the mass of remains was only 14%. The maxal peaks at 277℃ and 859℃ in DTG were observed by exothemic decomposed reaction, respectively. Conclusion During the storage period of the dried Soldago decurrein Lour powaer, the ambient temperature must be below 8℃. Among the making processes for it, the optimum temperature is below 210℃.
