Chemical composition and antimicrobial evaluation of the essential oils of Bocageopsis pleiosperma Maas

Abstract

Essential oils from the leaves, twigs and barks of Bocageopsis pleiosperma Maas were obtained by using hydrodistillation and analysed by using gas chromatography coupled to mass spectrometry. Several compounds (51) were detected and identified, being β-bisabolene the main component in all aerial parts of the plant, with higher concentration in the leaves (55.77%), followed by barks (38.53%) and twigs (34.37%). In order to increase the biological knowledge about the essential oil of Bocageopsis species, antimicrobial activities were evaluated against the microorganisms Escherichia coli, Staphylococcus epidermidis, Enterobacter aerogenes, Candida tropicalis, Candida dubliniensis, Candida glabrata and Candida albicans. The essential oil obtained from the barks exhibited a moderate effect against S. epidermidis ATCC 1228 (MIC = 250 μg/mL), while the other oils did not exhibit antimicrobial activity. These results represent the first report about the chemical composition of B. pleiosperma and the first antimicrobial evaluation with a Bocageopsis species.

Correlation between Chemical Composition and Antifungal Activity of Clausena lansium Essential Oil against Candida spp.

“…Antibacterial activity of essential oils of Tripleurospermum disciforme was reported that the reason for higher antibacterial effect is the presence of β-farnesene and β-sesquiphellandrene [23]. The essential oils of Bocageopsis pleiosperma Maas rich in β-bisabolene were reported to have high antifungal activities [24]. Their results are consistent with ours.…”

“…The chemical profile of essential oils from species of the Annonaceae family showed hydrocarbon and oxygenated sesquiterpenes as the main constituents, where the compounds β-bisabolene (55.77%), caryophyllene oxide (55.70%), and β-eudesmol (51.92%), were respectively dominant in the essential oils of Bocageopsis pleiosperma [ 22 ], Guatteria blepharophylla [ 23 ], and G. friesiana [ 35 ]. However, it was possible to observe other types of chemical classes in the genus Anonnace-ae, such as the oxygenated monoterpene cis -linalool oxide (33.10%) in the essential oil of Bocageopsis multiflora [ 24 ] and the alcohol 4-heptanol (33.80%) in the essential oil of Duguetia quitarensis [ 24 ].…”
