- Abstract
There is an emergent trend for the protection of geographical indication (GI) of medicinal plants, herbs and teas not only in the context of intellectual property rights, but also due to multiple concerns regarding contamination from polluted air, soil and water in some source countries, climate change, quality control and traceability. The mineral content coupled with chemometrics can be used to create elemental fingerprints. Lime flower (Tilia cordata), chamomile (Matricaria chamomilla), and Lady�s Bedstraw (Galium verum L.) of different provenience were used as plant material in this study. XRF spectrometry has been used for the determination of the mineral content of dry herbs. The results were compared with metal content values presented in different research papers and data bases and the elemental fingerprints of herbs were elaborated. Elemental fingerprints coupled with chemometrics can be used not only to evaluate the quality of herbs and teas, but also to authenticate the narrow-geographic origins of the plant material.
