This Application Note shows how, with the help of Vis-NIR spectroscopy and a special plant library, 46 different medicinal and aromatic plants, e.g., Organicum majoricum and Tilia cordata, can be conveniently identified on the basis of their spectrum. In comparison with alternative methods for the determination of plants, which are elaborate and require experienced scientists for their performance, the Vis-NIR method permits rapid and uncomplicated identification.
