Evaluation of the Toxicity of Virola sebifera Crude Extracts, Fractions and Isolated Compounds on the Nest of Leaf-Cutting Ants

open access: yesPsyche: A Journal of Entomology, 2012
The phytochemical study of Virola sebifera leaves led to the isolation of three lignans: (+)-sesamin, (−)-hinokinin, and (−)-kusunokinin and three flavonoids: quercetin-3-O-α-L-rhamnoside, quercetin-3-O-β-D-glucoside, and quercetin-3-methoxy-7-O-β-D ...
