[Studies on Niuxi with the method of FT-IR spectroscopy and analyze technology auxiliary].
OBJECTIVE
To study the genuine of 32 samples of Niuxi from 14 provinces, and compare some samples stored for different time to check the change in the coures of store.


METHODS
IR spectroscopy and Analyze Technology Auxiliary softeare.


RESULTS
The coefficient correlations had certain difference among these Niuxi from different places. They were divided into two parts if r = 0.9840 the standerd: trueborn crude drugs (r > 0.9840) and non-trueborn (r < 0.9840). And we can know the change in medicinal materials according r.


CONCLUSIONS
The method is operated simple and determined fast; the result is reliable; repetitiveness is good.
