“…Another study by Zatelli et al (2015) attributed anti-Mycoplasma activity of E. hiemalis to the essential oil component of the species. The isolated compounds in this study such as nerolidol (3) and the mixture of α,β amyrin (1,2) were inactive against the Mycoplasma strains.…”

The aim of this study was to evaluate the chemical composition and antimicrobial activity of four unexplored Eugenia species: Eugenia brevistyla, Eugenia handroana, Eugenia catharinae and Eugenia stigmatosa. Eight extracts and eighteen fractions were screened for their antibacterial activity against some selected bacteria including Mycoplasma. Phytochemical screening revealed that the plants were rich in terpenes and phenolic compounds. Antimicrobial evaluation revealed that E. handroana (FAEF-EH) and E. brevistyla (FAEF-EB) had the highest activity against Staphylococcus aureus with minimum inhibitory concentration (MIC) of 15.62 µg/ml Mycoplasma while FAEF-EH also presented the best activity with MIC of 62.5 µg/ml against Mycoplasma pneumonia M129. Some isolated compounds, betulinic acid and glutinol, also exhibited antibacterial property against some bacteria used in the study. All the four species studied presented promising antibacterial activity while the active principles are yet to be elucidated.

“…To our knowledge, isolation and biological activity of medium-chain fatty acids from the Eugenia genus have not been previously reported. Thus far, phytochemical studies of other Eugenia species with pesticidal properties have reported the presence of caryophyllene oxide, cineol, cymene, elemene, eudesmol, eugenol, furanodiene, furanoelemene, germacrene, linalool, phytol, Selina-1,3,7(11)-trien-8-one, and terpinene, as the most abundant metabolites in essential oils of leaves [22,23,24,25,26,27,37,39,40,41]. It was surprising to find that E. winzerlingii leaves do not biosynthesize essential oils.…”

Medium-Chain Fatty Acids from Eugenia winzerlingii Leaves Causing Insect Settling Deterrent, Nematicidal, and Phytotoxic Effects

et al. 2019

Eugenia winzerlingii (Myrtaceae) is an endemic plant from the Yucatan peninsula. Its organic extracts and fractions from leaves have been tested on two phloem-feeding insects, Bemisia tabaci and Myzus persicae, on two plant parasitic nematodes, Meloidogyne incognita and Meloidogyne javanica, and phytotoxicity on Lolium perenne and Solanum lycopersicum. Results showed that both the hexane extract and the ethyl acetate extract, as well as the fractions, have strong antifeedant and nematicidal effects. Gas chromatography-mass spectrometry analyses of methylated active fractions revealed the presence of a mixture of fatty acids. Authentic standards of detected fatty acids and methyl and ethyl derivatives were tested on target organisms. The most active compounds were decanoic, undecanoic, and dodecanoic acids. Methyl and ethyl ester derivatives had lower effects in comparison with free fatty acids. Dose-response experiments showed that undecanoic acid was the most potent compound with EC50 values of 21 and 6 nmol/cm2 for M. persicae and B. tabaci, respectively, and 192 and 64 nmol for M. incognita and M. javanica, respectively. In a phytotoxicity assay, medium-chain fatty acids caused a decrease of 38–52% in root length and 50–60% in leaf length of L. perenne, but no effects were observed on S. lycopersicum. This study highlights the importance of the genus Eugenia as a source of bioactive metabolites for plant pest management.

“…Previous studies have demonstrated that some species of Eugenia, such as E. beaurepaireana, E. brasiliensis, E. umbelliflora, E. hiemalis and E. platysema, exhibited promising antimollicute potential [3][4][5]. E. mattosii, the focus of this study (Cambuí), occurs in southern Brazil, but there are no studies on its chemical composition and biological activity.…”

The Eugenia genus is rich in bioactive substances with biological potential. Mollicutes are bacteria without cell walls, which are responsible for various human and animal diseases. The aim of this study was to evaluate the chemical composition and antimollicute activity of Eugenia mattosii. Leaves and stems were extracted with methanol, partitioned into fractions of different polarities, and submitted to column chromatography in order to isolate major compounds. Identification and quantification of isolated substances in extracts and fractions were performed by UPLC-PDA/ESI+-QTOF. Methanolic extracts, ethyl acetate and chloroform fractions and isolated substances were screened for antimycoplasmic activity against five Mycoplasma strains. The methanolic extracts of leaves and stems showed moderate antimycoplasmic activity (MICs = 250-500 µg.mL-1). The fractions exhibited better effect, with MICs = 125-1000 µg.mL-1 , especially the ethyl acetate fraction of the leaves, which presented MICs of 125-250 µg.mL-1 for all strains tested. Phytochemical analyses evidenced the presence of some phenolic compounds, including pinostrobin, cryptostrobin and catechin, the first showing promising antimycoplasmic activity. Quantification of the compounds demonstrated higher concentrations of pinostrobin and cryptostrobin in the chloroform fraction. In conclusion, E. mattosii presented antimycoplasmic activity related, at least in part, to the presence of pinostrobin.
