Chemotaxonomy of mints of genus Mentha by applying Raman spectroscopy
1Institut für Physikalische Chemie, Universität Würzburg, Am Hubland, Germany.
Abstract:
The characterization of mints is often problematic because Mentha is a taxonomically complex genus. In order to provide a fast and easy characterization method, we use a combination of micro-Raman spectroscopy and hierarchical cluster analysis. A classification trial of different mint taxa is possible for one collection time. For spectra measured at different points during the growing season, a more sophisticated pretreatment of the data is necessary to receive good discrimination between the species, as well as between the subspecies and varieties of the mints.
