“…Additionally, the results observed by Holetz et al [ 27 ], Domingues et al [ 40 ], Paula et al [ 41 ] and Correia et al [ 42 ] showed good activity against yeasts of other species of the Myrtaceae family, suggesting that compounds of M. tomentosa , as avicularin can be used as a potential antifungal.…”

This work describes the isolation and structural elucidation of compounds from the leaves of Myrcia tomentosa (Aubl.) DC. (goiaba-brava) and evaluates the antimicrobial activity of the crude extract, fractions and isolated compounds against bacteria and fungi. Column chromatography was used to fractionate and purify the extract of the M. tomentosa leaves and the chemical structures of the compounds were determined using spectroscopic techniques. The antibacterial and antifungal activities were assessed using the broth microdilution method. The phytochemical investigation isolated 11 compounds: α-bisabolol, α-bisabolol oxide B, α-cadinol, β-sitosterol, n-pentacosane, n-tetracosane, quercetin, kaempferol, avicularin, juglanin and guaijaverin. The crude ethanolic extract and its fractions were tested against 15 bacteria and 9 yeasts. The crude extract inhibited the in vitro growth of yeasts at concentration of 4 to 32 μg/mL. The hexane, dichloromethane, ethyl acetate and aqueous fractions inhibited Candida sp. at concentrations of 4 to 256 μg/mL, whereas the Cryptococcus sp. isolates were inhibited only by the hexane and dichloromethane fractions in minimal inhibitory concentrations (MICs) at 16 to 64 μg/mL. The flavonoid quercetin-3-O-α-arabinofuranose (avicularin) was the most active compound, inhibiting Candida species in concentrations of 2 to 32 μg/mL. The MIC values suggest potential activity of this plant species against yeast.

“…Keszei et al (2008) stated that the leaves of Myrtaceae species have high concentrations of terpenes and that these compounds show substantial qualitative and quantitative variations between each taxon, population and individual. Other phytochemical studies of Myrtaceae leaves have identifi ed sesquiterpenes, triterpenes, fl avonoids and alkaloids in Calycorectes psidiifl orus (Domingues et al 2010); fl avonoids, tannins and phenols in Plinia caulifl ora (Souza-Moreira et al 2010); and fl avonoids in Baeckea frutescens (Kamiya & Satake 2010).…”

Interspecific variation in the allelopathic potential of the family Myrtaceae

2013

Allelopathy is a type of biotic interference wherein a plant releases bioactive metabolites into an environment, thereby aff ecting the adjacent biota. Stressful environments stimulate the production of these metabolites. Th e present study tests the novel weapons hypothesis, which postulates that species belonging to the same genus and from the same environment have similar allelopathic eff ects. Th e aim of this study was to assess the allelopathic eff ects that the aqueous leaf extracts of 15 species belonging to fi ve genera of the Myrtaceae family have on the seed germination and initial seedling growth of lettuce (Lactuca sativa L.), tomato (Solanum lycopersicum L.) and onion (Allium cepa L.). Germination rates, average germination times, informational entropy of germination and allelopathic eff ects, as quantifi ed with a response index, were calculated. A taxonomic distance matrix based on Gower dissimilarity and a Euclidean distance matrix were constructed. Th e results revealed that all extracts from donor species signifi cantly increased average germination time or reduced the germination rate of eudicotyledonous plant species. Th e only extracts that showed no eff ect on monocotyledonous seeds were those of Campomanesia pubescens O. Berg and Psidium cinereum Mart. We conclude that eudicotyledonous and monocotyledonous plants were both signifi cantly aff ected by the presence of all extracts tested. Our results make it clear that each species behaves distinctly in relation to allelopathic activity, with no apparent grouping by genus or subtribe. Th erefore, the hypothesis was rejected, because plants from the same environment and with taxonomic proximity do not necessarily display similar production of secondary metabolites.

“…The presence of tannins, steroids, and saponins in the leaves of Gomidesia affinis and Gomidesia spectabilis of this family has been demonstrated (Sakita and Aguiar, 2006). In addition, there are triterpenes, flavonoids, and alkaloids in extracts of Calycorectes psidiiflorus (Domingues et al, 2010) and tannins and flavonoids in Pimenta pseudocaryophyllus. These are all from the same family (Paula et al, 2008), for the genus Myrcia, we found in the literature reports of phenolic compounds in Myrcia bela (Saldanha, 2013), Myrcia hiemalis (Silva, 2007) and Myrcia rotundifolia (Cerqueira et al, 2009).…”

Antimicrobial and insecticidal effects of essential oil and plant extracts of Myrcia oblongata DC in pathogenic bacteria and Alphitobius diaperinus

et al. 2022

View full text Add to dashboard Cite

The secondary metabolism products of plants have influenced great economic interest, given their chemical diversity and biological activities. Because of this, this study evaluates the phytochemical composition, antimicrobial activity, insecticidal, and antioxidant activity of plant extracts and oil of Myrcia oblongata. Saponins, steroids, triterpenoids, tannins, and flavonoids were detected. The extracts showed antimicrobial capacity on the tested microorganisms, except for the methanolic extract, which showed no activity for P. mirabilis and S. enteritidis. Regarding the analysis of antioxidant compounds, the hexanic, ethyl acetate and acetone extracts showed higher antioxidant activities and also higher insecticidal performance on Alphitobius diaperinus larvae, resulting in 80% adult mortality. The results reported here show that there may be a relationship between antioxidant potential and the insecticidal effect of Myrcia oblongata DC. The components present in both the extract and the oil can be used as natural alternative to synthetic compounds in the biological control of parasites and pathogenic microorganisms.
