The aim of WP2 is to determine the CT concentration and chemical characteristics of various processing methods and seasons
The CT in bark varies in quantity and quality. In the BarkCure project, we will test different ways to extract CT. Samples showing promising antiparasitic properties will be further characterized and fractionated and tested biologically in laboratory to find those with the strongest antiparasitic effect. Based on the biological test, structure and quantities of compounds in fractions with antiparaistic activity will be determined. Finally, an optimal industrial extraction process will be developed taking into account biological activity, extraction efficiency, costs and HMS-measure into account. Then, extracts showing highest bioactivity will be processed and tested in sheep.
