+ | "Black locust wood is being studied to find the chemical basis for its remarkable decay resistance. High flavonoid concentrations (6% of dry weight) are important, especially the constituents robinetin and dihydrorobinetin (Smith et al. 1989). When impregnated into easily decayed woods, heartwood extracts have raised decay resistance to a level equivalent to that attained by commercial wood preservatives (Smith et al. 1989)." | ||
