| 摘 要： | 目的：提供一种快速简单的方法鉴别贝母类中药材。方法：采用热分析方法(TG,DTA)对9种贝母类中药材的热重/差热图谱进行分析。结果：通过分析9种不同贝母中药材粉末的热重/差热图谱发现,由于来源不同,地理环境和气候的差异,不同贝母类中药材的热分析图谱之间存在较大的差异。湖北贝母的热稳定性最高,平贝母的热稳定性最差,不同的贝母具有各自的差热图谱。结论：根据9种贝母中药材热分析图谱之间的差异,可以很容易的对其进行区分和鉴别。 |

| Abstract: | Objective: To provide a quick and simple method to identify different Chinese medicine material of Fritillaria. Method: The thermograms and differential thermograms of nine Fritillaria powders were obtained by thermal analyzer. Result: By analyzing the thermograms of nine Fritillaria powders, we concluded that the thermal stability of nine Fritillaria powders was much different each other due to the different geography origin. The thermal stability of F. hupehensis was highest among nine Fritillaria, while F. ussurensis was the lowest. The different Fritillaria showed their own DTA spectra respectively. Conclusion: According to the differences in the thermal properties of nine Fritillaria powders,the origins of Fritillaria could be easily identfied. |
