Abstract:
In this paper, Fourier transform infrared spectroscopy fingerprint analysis of Marsdenia tenacissima samples was used to develop a reliable method of tracing the geographical origins. Forty-eight samples from four provinces of China were analyzed by FTIR. We analyzed and characterized the fingerprints in both the full spectrum peaks and characteristic peaks, then the principal component analysis and the cluster analysis were carried out. The results of fingerprint analysis, correlation analysis, principal component analysis and cluster analysis can identify the geographic origins correctly, which verified and supplemented each other; the identification results and the actual location showed a high degree of consistency, namely the lower the space distance, the greater the similarity of different samples. These results revealed the obvious superiority and practical value in comparison to the more tedious and time-consuming wet chemistry method normally used. Using appropriate metrology methods can trace the geographical source correctly. The M. tenacissima materials from the region of Maguan should be considered as genuine medicinal materials taking into account the good quality.
