Interference of Seasonal Variation on the Antimicrobial and Cytotoxic Activities of the Essential Oils from the Leaves of Iryanthera polyneura in the Amazon Rain Forest

Abstract: The essential oils (EOs) obtained from the leaves of Iryanthera polyneura Ducke trees was chemically Assessed and tested for the ability of inhibiting the growth of Candida albicans, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus mutans and S. sanguinis. The oil was also tested against breast (MCF‐7) and prostate (PC‐3) cancer cell lines. Minimum bactericidal concentrations (MBCs) and 50 % inhibition concentrations (IC50) values were obtained. EOs were act… Show more

“…The species Iryanthera polyneura (Myristicaceae) is commonly known as cumala-colorada, and can be found in the Amazon forest [ 93 ]. Studies on this species have shown cytotoxic activity [ 39 ] for the essential oil from the leaves of three specimens of Iryanthera polyneura collected in Amazonas, Brazil, which were tested against human breast (MCF-7) and prostate (PC-3) cells. In that study, thirty-six of the forty essential oils were more active against PC-3 than against MCF-7 cells, where the samples of the set 22EO, 80EO, and 53EO were particularly active, with inhibition values of IC 50 = 14.69 ± 4.33, 13.63 ± 3.23, and 12.48 ± 4.03 μg/mL, respectively.…”

“…EOs obtained from leaves collected in the rainy season were more active against MCF7. STs spathulenol, α-cadinol, and τ-muurolol were identified as the main compounds [61]. Some seasonal variation was also found in EO of Mentha species, M. arvensis, M. piperita, M. longifolia, and M. spicata, and they all stimulated the decrease of MCF7 proliferation.…”

“…They were tested against Sau and against breast and prostate human cancer cell lines to evaluate possible correlations of the biological activity to both dry and rain seasons (Table 1). Multivariate analyses are being regularly used to cope with the interpretation of data obtained from essential oil compounds and their relationship with factors as biological activities [15], seasonal expression, and analysis of the influence of climatic factors [14] on the essential oil production [16]. Cluster analysis and PCA were adopted as a tool to discriminate three Myrtaceae essential oils [17], while PCA was used to discriminate clones of Juniperus communis and wild Juniperus sp.…”
