To detect the change of Niuxi in reserve and establish one easier method of evaluating the quality change of Niuxi.
Infrared spectroscopy and compare software were used to distinguish the different Niuxi, and simulation testing were used to observe calefactive stability.
There were obvious difference between transmutative and normal Niuxi, and Niuxi had evident change when the temperature above 140 degrees C in the simulation testing.
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.
检测牛膝储备期间的变化，建立一种更简便的牛膝质量变化评价方法。
采用红外光谱法及比较软件鉴别不同牛膝，并通过模拟试验观察加热稳定性。
变异牛膝与正常牛膝有明显差异，模拟试验中温度高于140℃时牛膝有明显变化。
红外光谱法可用于评价牛膝的质量稳定性。这是一种尝试性的方法，可为储备及炮制条件的建立提供依据。
