1Henan College of TCM, Zhengzhou 450008.
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.
Result:
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%.
Conclusion:
The method is fast, accurate.

Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0% (complete...
