Study on Analysis and Assessment of Agrimonia pilosa Ledeb from China and Korea with FT-IR

Aim: To get the IR spectrums of Agrimonia Pilosa Ledeb (APL) from china and korea areas, and to find out the characters of IR spectrums through the content of different chemical constituents, provide a fast and effective analysis method monitor the inherent qualities of traditional Chinese medicine-APL. Method: Fourier transform infrared spectroscopy (FT-IR) was applied to detect sample of APL from china and korea areas. Result: this study showed that the IR spectra of APL from china and korea areas have their unique IR fingerprint features. The content of gallate and calcium oxalate in APL from china is significantly higher APL from korea. So FT-IR is a very quick, effective and well repetitive method for monitoring and distinguishing the traditional Chinese medicine.
