Collaborative project: Identification and reduction of pyrrolizidine alkaloid containing plants as contamination in herbal and medicinal plants by (hyperspectral) near-infrared spectroscopy (PA-NIRSort)
Project
Project code: 22013216
Contract period: 01.03.2019
- 28.02.2022
Budget: 81,976 Euro
Purpose of research: Experimental development
Keywords: biodiversity, medical and aromatic plants, renewable ressources
The aim of this project is the development of a new, non-invasive analytical method for fast detection of pyrrolizidine alkaloid (PA) containing plant-derived contaminations in cultural plants, e.g. medicinal and aromatic plants. Such PA containing plants (i.e. comfrey, borage, echium, senecio ...) and parts of them should be detected by NIRS and hyperspectral NIR-imaging. Based on identification of characteristic spectral ranges and correlation analysis, appropriate discrimination models should be developed allowing the quantitative separation of target plants and PA contaminants. Furthermore, PLS models should be investigated allowing a quantitative estimation of the level of contamination both, in fresh and dried material. In the related partner project, multivariate statistics should be applied for reducing the corresponding large volume of data for developing an appropriate detection unit able to recognize contaminations on continuously moving flat-conveyers within few seconds. In combination with suitable separation unit this technique should be applicable for dried plants (herbal drugs) as well as fresh plant material.
