“…Several studies on Lauraceae species have shown that changes in the chemical composition and yield of EO can be affected by humidity, temperature, seasonality, luminosity, photoperiod, geographic variations, plant age, tissue collected and phenologic stages [24,47,50]. The variations in the chemical composition in the oil from the leaves presented in this study are illustrated in Figure 3.…”

“…Besides, other tissues of O. lancifolia also had high levels of oxygenated sesquiterpenoids such as the inflorescences (81.3%) and fruits (69.1%). Once again, caryophyllene oxide (27.9-52.1%) was the most abundant compound [50].…”

“…Caryophyllene oxide was the main compound of the EO from Ocotea acutifolia (Nees) Mez, and O. lancifolia (Schott) collected in São Francisco de Assis and Santa Maria (RS), respectively [49,50]. The oil of O. acutifolia was dominated by caryophyllene oxide (56.9%), and calarene epoxide (11.74%) and the specimens of O. lancifolia oils presented caryophyllene oxide (39.4-46.4%) and allo-himachallol (5.7-8.0%).…”

“…The chemical composition varies among specimens of the same species of Licaria, Nectandra and Ocotea; the oils and the combination were characterized by their chemical profiles, which are based on the concentrations of the major components. These different chemical profiles may be associated with respect to ecological and geographical condition, age of plant and time of harvesting [24,32,50].…”

Lauraceae species are known as excellent essential oil (EO) producers, and their taxa are distributed throughout the territory of Brazil. This study presents a systematic review of chemical composition, seasonal studies, occurrence of chemical profiles, and biological activities to EOs of species of Licaria, Nectandra, and Ocotea genera collected in different Brazilian biomes. Based on our survey, 39 species were studied, with a total of 86 oils extracted from seeds, leaves, stem barks, and twigs. The most representative geographic area in specimens was the Atlantic Forest (14 spp., 30 samples) followed by the Amazon (13 spp., 30 samples), Cerrado (6 spp., 14 samples), Pampa (4 spp., 10 samples), and Caatinga (2 spp., 2 samples) forests. The majority of compound classes identified in the oils were sesquiterpene hydrocarbons and oxygenated sesquiterpenoids. Among them, β-caryophyllene, germacrene D, bicyclogermacrene, caryophyllene oxide, α-bisabolol, and bicyclogermacrenal were the main constituents. Additionally, large amounts of phenylpropanoids and monoterpenes such as safrole, 6-methoxyelemicin, apiole, limonene, α-pinene, β-pinene, 1,8-cineole, and camphor were reported. Nectandra megatopomica showed considerable variation with the occurrence of fourteen chemical profiles according to seasonality and collection site. Several biological activities have been attributed to these oils, especially cytotoxic, antibacterial, antioxidant and antifungal potential, among other pharmacological applications.
