“…In previous studies, yields of 0.5% and 1.8% for E. uniflora oil were reported in two samples collected in north and south Brazil, respectively [30,31]. A seasonal study of the oil of a specimen of E. uniflora from the Brazilian Midwest indicated that its oil yield in the rainy period (0.3 ± 0.3%) was similar to that of the dry period (0.2 ± 0.2%).…”

The essential oil of Eugenia uniflora has been attributed anti-depressive, antinociceptive, antileishmanial, larvicidal, antioxidant, antibacterial, and antifungal activities. It is known that the cultivation of this plant can be affected by seasonality, promoting alteration in the oil composition and its biological activities. This study aims to perform the annual evaluation of the curzerene-type oil of E. uniflora and determine its antioxidant activity. The oil yield from the dry season (1.4 ± 0.6%) did not differ statistically from that of the rainy season (1.8 ± 0.8%). Curzerene, an oxygenated sesquiterpene, was the principal constituent, and its percentage showed no significant difference between the two periods: dry (42.7% ± 6.1) and rainy (40.8 ± 5.9%). Principal component and hierarchical cluster analyses presented a high level of similarity between the monthly samples of the oils. Also, in the annual study, the yield and composition of the oils did not present a significant correlation with the climatic variables. The antioxidant activity of the oils showed inhibition of DPPH radicals with an average value of 55.0 ± 6.6%. The high curzerene content in the monthly oils of E. uniflora suggests their potential for use as a future phytotherapeutic alternative.

“…The yield of Eugenia essential oil was obtained in this study was 0.5%, composed of 57 compounds, but the highest compounds are Spathulenol (12.03%) and dodecanol (11.78%), both of them almost in the same amount, then followed by dodekanal (4.16%), β-elemen (4.08%), and caryophyllene (2.97%). According to the report of [42], five dominant compounds of 16 compounds in the essential oil of E. uniflora: caryophyllene (8.812%), spathulenol (7.712%), isolongifolene (6.621%), viridiflorol (5781%), and alloaromadendrene (5.568%).

Potential of Essential Oils

View full text Add to dashboard Cite

The antibacterial activity of essential oil of five Indonesian herbs has been studied. The essential oil produced from different parts of plants (lime, lemon, Surinam cherry, fennel, and toothache plants) were extracted by water steam or hydro distillation and then examined by GCMS. The antibacterial activities of the essential oils were determined by measuring MIC (minimum inhibitory concentration), whereas some bacterial strains were used in this study such as follows: Staphylococcus aureus FNCC 0047, Bacillus subtilis ATCC 6051, B. cereus FNCC 0057, Escherichia coli IFO 0091, Pseudomonas cepacia FNCC 0063, and P. aeruginosa FNCC 0063, respectively. All the five samples used in this experiment have antibacterial activity against Gram-positive and Gramnegative bacteria. Gram-negative bacteria appear more resistant than Gram-positive bacteria. By using MIC measurement the Gram-positive and Gram-negative bacteria showed different sensitivities toward essential oils. Among the material study, the essential oil of Eugenia uniflora L (Surinam cherry) showed the highest antibacterial activity.

“…Muitas espécies vegetais nativas já servem como fonte de pesquisas a fim de descobrir suas atividades biológicas. (Rosa et al, 2016) Nesse sentido, os óleos essenciais (OEs) presentes em plantas aromáticas, são substâncias provenientes do metabolismo secundário, constituídas por substâncias voláteis, e seus compostos orgânicos são as principais substâncias com ação terapêutica (Almeida, 2015;Becker et al, 2017;Rosa et al, 2016). Recentemente, foram reconhecidos como poderosos antioxidantes naturais, podendo ser utilizados como substitutos em potenciais aos antioxidantes sintéticos na indústria alimentícia e farmacêutica, além disso, representam uma abordagem interessante contra a ocorrência da resistência de patógenos microbianos aos medicamentos atuais.…”

O Brasil apresenta a maior biodiversidade no mundo e neste contexto, suas espécies nativas tornam-se uma alternativa na busca por moléculas bioativas para bioprospecção de antimicrobianos e antioxidantes naturais. Pertencente à família Myrtaceae, a espécie Myrcia palustris DC, conhecida popularmente como pintagueira-do-mato, não apresenta estudos referente às suas atividades biológicas e composição química. Diante disso, o objetivo deste trabalho foi determinar a composição química do óleo essencial de M. palustris por cromatografia gasosa acoplada à espectrometria de massas (CG-EM), avaliar sua atividade antimicrobiana pela técnica de microdiluição em caldo e a atividade antioxidante pela técnica de 2,2-difenil-1-picril-hidrazila (DPPH). O rendimento total a partir da extração pela técnica de hidrodestilação do óleo essencial foi de 0,35%. A CG-EM revelou a presença de 28 compostos, sendo a maioria da classe dos sesquiterpenos. A atividade antimicrobiana foi observada para todas as bactérias Gram-positivas (Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus) com exceção de Staphyloccocus epidermidis. Em relação às Gram-negativas, verificou-se atividade inibitória apenas para Shigella flexneri. Para levedura Candida albicans não foi observada atividade inibitória e nem fungicida. O óleo essencial apresentou capacidade de redução de radicais de DPPH até 82,81%, confirmando seu potencial antioxidante. Sugere-se que a ação antimicrobiana e antioxidante presentes no óleo essencial de M. palustris esteja relacionada à presença dos compostos majoritários α-Guaieno (25,89%), α-Bulneseno (13,39%) e β-Selineno (4,76%).
