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.
目的
提供一种快速简便的方法来鉴别不同的川贝母药材。
方法
采用热分析仪获得九种川贝母粉末的热谱图和差示热谱图。
结果
通过分析九种川贝母粉末的热谱图，我们得出结论，由于产地不同，九种川贝母粉末的热稳定性差异很大。湖北贝母在九种川贝母中热稳定性最高，而平贝母最低。不同的川贝母分别呈现出各自的差示热分析图谱。
结论
根据九种川贝母粉末热性质的差异，可以很容易地鉴别川贝母的产地。
