“…The main constituent eugenol in COsWh (77.1%), COsI (78.8%), and COsWm (78.7%) of leaf and the second main constituent was β-caryophyllene (19.6%, 17.0% and 18.3%, respectively). Other studies have also reported high concentrations of eugenol in leaf clove oil 81.0% to 86.0% at growing area Amboina Island (Sohilait et al 2019) and 78.3% in West Amboina Island (Sohilait et al 2018).…”

The essential oils of clove species Eugenia caryophyllata (COs) from northern Buru Island were obtained by steam distillation. The chemical components were characterized by gas chromatography (GC-FID) and GC-mass spectrophotometry (MS). In total, five components were identified in COs of leaf, four components were identified in COs of bud, and two components were identified in COs of stem. The main constituents are eugenol (77.1% to 78.8%) and β-caryophyllene (17.0% to 19.6%) in COs of leaf. The main components are eugenol (76.1% to 87.7%) and eugenyl acetate (6.0% to18.9%) in COs of bud and the only main component was eugenol (94.2% to 97.6%) in COs of stem from Waihani (COsWh), Ilath (COsI) and Waimoli (COsWm). The antioxidant activity COs of leaf, bud, and stem was identified using DPPH and ABTS assay. Results showed that COsI of bud had higher ABTS free radical scavenging (IC50 value: 0.09 ± 0.61 μg/mL) than the eight samples in the study. When this activity was compared with synthesis antioxidant of BHT (IC50 value: 0.83 ± 0.54 μg/mL) and AA (IC50 value: 0.81 ± 1.64 μg/mL), the COs in three locations show potential of being used as an antioxidant.

“…Outro composto químico com este mesmo efeito é o Eugenol (Nisar et al, 2021). Ele pode ser encontrado na espécie E. caryophyllata (Sohilait et al, 2018). Diversos estudos indicam que essa molécula tem efeito antimicrobiano e antioxidante (Marchese et al, 2017, Semnani et al, 2018, além de anti-inflamatório (Han & Parker, 2017).…”

A resistência aos antifúngicos é um problema na saúde global, sendo necessário buscar alternativas de controle e tratamento. Há relatos cientificos que evidenciam o potencial de ação antigfúngica de óleos essenciais. A pesquisa teve como objetivo principal avaliar o perfil de sensibilidade da C. albicans através do uso de óleos essenciais. Tratou-se de um estudo experimental com abordagem quantitativa da ação antifúngica de óleos essenciais frente a cepa C. albicans ATCC, obtidas comercialmente. Efetuou-se a seleção dos óleos essenciais através das recomendações da Farmacopeia Brasileira. A cepa foi mantida em repiques sucessivos em meio de cultura TSA, até utilização nos testes de suscetibilidade. A atividade antifúngica dos óleos essenciais foi realizada pela técnica da difusão em ágar em poços. Constatou-se que todos os óleos essenciais conseguiram sensibilizar a cepa C. albicans. Com destaque para C. cassia com formação de halo de inibição de 40mm de diâmetro e menor potêncial ao E. globulus com halo de inibição de 12mm. O presente estudo evidenciou que os óleos essenciais testados possuem propriedades antifúngicas sobre a cepa C. albicans, entretanto, com distintos perfis de suscetibilidade. Além disso, os dados obtidos permitem expandir o conhecimento acerca dos produtos de origem vegetal com potencial antifúngico. Sugere-se que novas pesquisas devem ser realizadas nesta linha de investigação com o propósito de identificar outros óleos essencias com essa ação e seus fitoconstituintes.
