摘要
目的:探讨牛膝药材贮存中质量变化,并建立宏观检测的快捷简便方法。方法:采用红外光谱技术结合计算机辅助比对软件技术,对牛膝药材贮存过程中的药材质量的变化进行了比较研究,并对牛膝药材的热稳定性进行了模拟实验。结果:从红外光谱谱图上可以将变质药材与正常药材区别开来,同时热稳定性模拟实验表明,当温度升至140℃时,牛膝药材的红外光谱开始发生明显变化。结论:红外光谱技术可以作为一种宏观的药材质控方法,同时也可以为中药材的贮存和干燥等条件的确定提供可靠依据。
Objective ： To detect the change of Niuxi in reserve and establish one easier method of evaluating the quality change of Niuxi. Methods： Infrared spectroscopy and compare software were used to distinguish the different Niuxi, and simulation testing were used to observe calefactive stability. Results： There were obvious difference between transmutative and normal Niuxi, and Niuxi had evident change when the temperature above 140℃ in the simulation testing. Conclusion： Infrared spectroscopy can be used to evaluae the quality stability of Niuxi. It is one tried method to provide the establishment of reserve and torrefaction conditions.
