Abstract:
Lignin is a co-product from the biorefinery and paper industries. Its non-energetic valorisation remains a field of extensive research and development. In this perspective, this study was undertaken to evaluate the radical scavenging ability of selected herbaceous lignins. These lignins, extracted from either Miscanthus (Miscanthus × giganteus) or switchgrass (Panicum virgatum L.), were selected as benchmarks for this study based on their chemical structure and average molecular weight. These technical lignins, which are side-products in the bioethanol production process, displayed a moderate antioxidant activity as evaluated by the 1,1-diphenyl-2-picrylhydrazil free radical scavenging test system. A correlation between the radical scavenging properties and the molecular features is proposed and discussed. Infrared spectroscopy was employed as a straightforward qualitative prediction tool for assessing the radical scavenging capacity.
