[Identification of categories of Radix Rehmannia by IR spectroscopy and compare software].
OBJECTIVE
To identify the categories of Radix Rehmannia between the wild and the planting, different stored time, (gained in 2000,2002) , trueborn place (Henan) and no-trueborn places.


METHODS
FTIR combined compare software, and the data was dealt with the means of normalization in computer.


RESULTS
The wild and the planting have evident difference. They can be identified for the different stored-time completely. The identification percentage between trueborn place and no-truedborn places is more than 90%.


CONCLUSIONS
The method is fast, accurate.
