Qualitative Identification of Spatholobus suberectus by Near-infrared Spectroscopy / 世界科学技术-中医药现代化

ABSTRACT

This study was aimed to establish an identification method for Spatholobus suberectus and its adulterants by near-infrared spectroscopy (NIRS). Near-infrared diffuse reflection spectroscopy (NIRDRS) spectra of different S. suberectus and its adulterants were acquired by using OPUS INDENT analysis software. NIRDRS spectra clustering analysis model and identification model were established and verified. The results showed that S. suberectus from dif-ferent regions and its adulterants were identified successfully by clustering analysis model and identification model. It was concluded that Spatholobus suberectus and its adulterants can be identified rapidly and non-destructively by NIRS.
