“…and Myrcia fallax (Rich.) DC, which contained 0.07, 0.20, 0.33 and 0.25%, respectively, in studies by Magina et al (2009) and Alarcón et al (2009). The yield of essential oils in the fresh flowers was 0.31% (v/w), a value close to that obtained by Alarcón et al (2009) for Myrcia fallax flowers.…”

“…Studies examining the composition and biological properties of the essential oils found in several species of the Myrtaceae family (Limberger et al, 2001;Franco et al, 2005;Zabka et al, 2009;Magina et al, 2009) have been reported, and their antimicrobial properties have been emphasized. The work of Cerqueira et al (2007) on seasonal variation and antimicrobial activity and Alarcón et al (2009) on chemical composition and antibacterial activity are examples of such antimicrobial studies for the genus Myrcia.…”

Species in the Myrtaceae family are used in folk medicine to treat gastrointestinal disorders, infectious diseases and hemorrhagic conditions and are known for their essential oil contents. Gas chromatography coupled with mass spectrometry (GC-MS) was used to characterize the chemical composition of essential oils of the leaves, stem bark and fl owers of Myrcia tomentosa (Aubl.) DC., as well as to assess the chemical variability in the constituents of the essential oils of the leaf. Soil and foliar analyses were also performed to determine the mineral compositions. Principal component analysis (PCA) was used to examine the interrelationships between the obtained data. The most abundant component in the essential oils of the fl owers was (2E,6E)-methyl farnesoate, whereas hexadecanoic acid was the most abundant essential oil component in the stem bark. The leaf essential oils showed seasonal variation in their chemical composition, with bicyclogermacrene and (2E,6E)-methyl farnesoate as the major chemical components. Forty-four constituents were identifi ed, and only nine compounds were found in all of the samples. Sesquiterpenes were mainly produced in the fl owers and leaves. The PCA showed a positive correlation between the oxygenated sesquiterpenes and the foliar nutrients Cu and P. Signifi cant statistical correlations were verifi ed between the climatic data, foliar nutrients and essential oil compositions.

“…13 Ursolic acid has been isolated from the leaves of E. brasiliensis 14 and anthocyanins, ellagic acid, myricetin, quercetin, quercitrin and rutin have also been detected in the fruits. 15 Our studies have shown that the essential oil extracted from the leaves of E. brasiliensis has an appreciable antibacterial activity, 16 while the crude hydroalcoholic extract of the leaves and fractions has anti-inflammatory activity. 17 The use of a simple microorganism such as Artemia salina to test in vivo lethality can represent a simple tool for guiding the screening and fractionation of physiologically active plant extracts.…”

Recebido em 10/10/11; aceito em 17/1/12; publicado na web em 15/5/12 A chemical investigation of Eugenia brasiliensis Lam. (Myrtaceae) leaves led to the isolation of a-amyrin and b-amyrin (in a mixture), betulin, 29-hydroxy-oleanolic acid, quercetin, catechin and gallocatechin. Herein, the identification of 29-hydroxy-oleanolic acid is reported for the first time in the Myrtaceae family. Moreover, in this study, the extract, fractions and six of the seven compounds were monitored for toxicity toward Artemia salina, antibacterial and acetylcholinesterase inhibitory activity. The crude ethanol extract of the leaves and fractions were found be active on A. salina toxicity bioassay.

“…The essential oil extracted from its leaves presented anti-diarrhea, anti-fever, anti-infllamatory, and antibacterial activities (Magina et al, 2009). Little is known about the antimicrobial effects of the fruit and no study has been found reporting its anti-quorum sensing activity.…”

Anti-quorum sensing activity of phenolic extract from Eugenia brasiliensis (Brazilian cherry)

et al. 2016

View full text Add to dashboard Cite

The aim of this study was to assess the anti-quorum sensing activity of phenolic extracts from grumixama (Eugenia brasiliensis), also known as Brazilian cherry, in concentrations that did not interfere with bacterial growth. The pulp phenolic compounds were extracted by using solid phage extraction in a mini-collumn C18 and quantified by spectrophotometry. The anti-quorum sensing activity was evaluated by testing the inhibition of violacein production in Chromobacterium violaceum and by evaluating the swarming motility in Aeromonas hydrophila and Serratia marcescens, both phenotypes regulated by quorum sensing. The phenolic extract strongly inhibited the production of violacein in C. violaceum, reducing its production in comparison with a control with no extract. No inhibition of growth was observed at the concentrations tested for quorum sensing inhibition. Confirming the quorum sensing inhibition phenotype, the extract was also able to inhibit swarming motility in S. marcescens and in A. hydrophila, although in the later the effect was marginal. Dverall, these results indicate that phenolic extract from E. brasiliensis presents quorum sensing inhibitory activity most likely due to the presence of fruit phenolics which have been implicated as quorum sensing inhibitors in Gram negative bacteria.Keywords: quorum sensing; anti-quorum sensing; phenolic extract; Brazilian cherry; Eugenia brasiliensis. Practical Application:The phenolic extract in this study presents potential applications in the food and pharmaceutical industries due to inhibition of phenotypes regulated by quorum sensing, which include production of virulence factors and spoilage enzymes. By inhibiting phenotypes associated with quorum sensing, the extract presents potential application as a natural preservative for food conservation and as an alternative or an adjuvant with antibiotics.
