[Infrared spectral identification of rhizoma Corydalis and rhizoma Corydalis repentis].
OBJECTIVE
To study the IR spectra of Rhizoma Corydalis and Rhizoma Corydalis Repentis.


METHODS
The petroleum ether, ethyl ether and water extracts obtained by the same isolating procedure from Rhizoma Corydalis and Rhizoma Corydalis Repentis were determined by IR spectrophotometry.


RESULTS
The IR spectral evidences of the two samples showed distinct characteristics and good repeatability.


CONCLUSIONS
The IR spectral evidences can be used to differentiate Rhizoma Corydalis and Rhizoma Corydalis Repentis.
