This thesis examines the phytochemical discovery process from temperate and tropical trees. Thirty extracts of wood and bark of hardwood trees from Eastern North America were examined for insect control and antimicrobial activities. Nine of the bark extracts and four of the wood extracts showed significant growth reducing effects against Ostrinia nubilalis at 0.5%, whereas only two bark extracts and one wood extract showed significant antifeedant effect against Sitophilus oryzae at the same concentration. Slower growing tree species were more biologically active than fast growing ones. Isolation of the bioactive compounds in one of the active species, Prunus serotina, showed that naringenin, its derivative 4 'methoxynaringenin, and eriodic...
