Seasonal variance in the chemical composition of essential oils from Lantana camaraaccessions and their trypanocidal activity on Phytomonas serpens

The objective of this study was to investigate the seasonal variance content and chemical composition essential oil from Lantana camaraaccessions at two harvest times, analyze trypanocidal activity on Phytomonas serpens. Essential ranged 0.13 0.29% in rainy season 0.33% dryseason. compounds E-caryophyllene, α-humulene, α-curcumene germacrene D defined formation four clusters dry seasons, classified as: Cluster 1 (E-caryophyllene + D); 2 (germacrene E-caryophyllene); 3 (α-humulene 4 (α-curcumene E-caryophyllene). All L. camaraessential oils, representing clusters, inhibited P. serpenswith low concentrations, considering following IC50values: 18.34±6.60 μg/mL (LAC-018, 1); 9.14±3.87 (LAC-027, 2); 14.56±3.40 (LAC-037, 3); 14.97±2.68 (LAC-019, 4).
