Abstract

Objective: To study the IR spectra of Rhizoma Corydalis and Rhizoma Corydalis Repentis.

Method: 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.

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