“…In this study, we signicantly expanded the detection and annotation of glycosylated avonoids in six Ocotea species, surpassing previous metabolomics and phytochemical counts in the literature. More specically, only a few avonoids were reported for these species: O. diospyrifolia (only 2), 13 O. guianensis (6), 54 O. lancifolia (9), 61 O. notata (12), 55,60,62 O. odorifera (11), 57 and O. porosa (only 3), 97 and our study annotated more than 50 avonoid backbones for each species (ESI 7 -Table S5 †). Except for O. notata, apigenin fragment backbones have been identied in the ve other Ocotea species.…”

“…Para o método ORAC (Oxygen Radical Absorbance Capacity), a partição de acetato de etila apresentou características anti-oxidantes melhores que o obtido em Ginkgo biloba. Ademais, também demonstrou que as frações com a mistura de flavonoides têm um potencial antioxidante superior quando comparadas aos flavonoides isolados, sugerindo um efeito sinérgico (Pereira et al, 2020). Aniba rosaeodora (Var.…”
