“…collected in Marcelino Ramos (RS) showed phenylpropanoids (40.23%, 42.0%), oxygenated monoterpenoids (34.35%, 43.0%) and monoterpene hydrocarbons (16.1%, 10.8%). Safrole (42.0%, 40.23%), camphor (43.0%, 34.35%), camphene (6.0%, 5.0%) and limonene (7.42%, 3.0%) were the most representative compounds [53,54].…”

“…The specimen collected in Machado (MG) showed safrole (36.3%) to be the main compound followed by low amounts of γ-cadinene (6.6%) and camphor (6.5%) (profile I) [55]. Likewise, camphor (43.0%, 34.35%), safrole (42.0%, 42.0%), and camphene (6.0%, 5.02%) were the major compounds of profile II from the city Marcelino Ramos (RS) [53,54].…”

“…In general, a higher potential was observed for Gram-negative (8.40-15.40 mm) than for Gram-positive bacteria (7.90-11.80 mm). Unfortunately, minimum inhibitory concentrations (MIC) were not determined [54] Furthermore, leaves of L. puchury-major from Borba (AM) were tested against Pseudomonas aeruginosa, E. coli, Streptococcus agalactiae and S. aureus. This species of EO was composed mainly of safrole (39.40%), 1,8-cineole (28.00%) and sabinene (8.50%).…”

“…The plant exhibited very weak antibacterial properties against Escherichia coli (winter, MIC 6.5%; spring, MIC 4.25%; summer, MIC 10.1%; Fall, MIC 10.1%), and Staphylococcus aureus (winter, MIC 1.9%; spring, MIC 1.8%; summer, MIC 1.9%; fall, MIC 3.0%) throughout the seasons [23]. [38] Stem Bark: β-eudesmol (27.51%), α-pinene (9.02%), limonene (6.65%), and borneol (6.18%) Fruits: limonene (30.12%), β-pinene (12.25%), α-pinene (9.89%), and myrcene (7.86%); Roots: elemol (24.31%), β-elemene (16.69%), β-eudesmol (13.44%), and borneol (3.69%) 46.03 mg/mL) [54] O. splendens Manaus, AM Leaf β-caryophyllene (51.0%), caryophyllene oxide (9.90%), α-humulene (6.20%)…”

“…The species O. odorifera, containing safrole (40.23%), camphor (34.35%) and limonene (7.42%), showed 33.96% and 86.45% of free radical inhibition at 10.0 and 150.0 µg/mL [54]. The leaf EO of O. bicolor from Curitiba (PA) was mainly composed of δ-cadinene (7.39%), β-sesquiphellandrene (6.67%) and β-elemene (5.41%).…”

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.

A Química é uma área da ciência que estuda a matéria e suas interações com o ambiente. Alguns desses conceitos podem ser considerados de difícil compreensão por alunos do Ensino Médio, considerando que muitas vezes são utilizadas ideias subjetivas para tentar explicar conteúdos como, por exemplo, de grupos funcionais e cadeias carbônicas. Considerando isso, esta pesquisa tem como objetivo contextualizar as aulas experimentais de Química Orgânica com o cotidiano do estudante, na intenção de despertar seu interesse e colaboração nas aulas. A partir desse objetivo, foi planejada uma maneira de associar o conteúdo com algum objeto de fácil acesso ao estudante, de forma que fosse possível visualizar, através do objeto, o assunto que ele aprendeu em sala de aula, tornando o aprendizado significativo. A metodologia adotada neste trabalho foi uma abordagem qualitativa da pesquisa participante, na qual através da extração dos óleos essenciais de capim-santo (Cymbopogon citratus) e laranja-pêra (Citrus sinensis), pelo método de hidrodestilação, foram produzidos aromatizadores de ambiente, que os alunos levaram para casa, como lembrança da aula prática e do conteúdo revisado. Como avaliação da atividade, foi aplicado um questionário, em que os alunos expuseram seu nível de satisfação, opinaram se desejavam mais atividades contextualizadas no ensino da Química e sugeriram melhorias para a atividade; além de classificarem a cadeia carbônica e identificarem os grupos funcionais dos componentes majoritários presentes nos óleos essenciais de capim-santo (citral) e laranja-pêra (limoneno). As respostas dos estudantes, ao questionário, permitiram observar a apreensão do conhecimento abordado através dos experimentos realizados.
