“…Therefore, in the dry season these constituents are present in higher concentrations. The chemical constituents carvacrol and p -cymene are described in several studies as major constituents; nevertheless, in this species, they were not identified or had low contents [ 29 , 30 , 31 ].…”

Insect resistance and environmental pollution are among the drawbacks of continuous use of synthetic insecticides against the vectors of dengue, Aedes aegypti and Aedes albopictus. The objective of this study was to analyze the composition of the essential oil of Lippia grata Schauer collected from plants, in three periods of the year, to compare the larvicidal activity and enzymatic inhibition of the dengue vectors. The oilsanalyzed by gas chromatography coupled to mass spectrometry (GC-MS), presented thymol and 1,8-cineole, as the main constituents, in all three periods. This composition was different from that found in previous studies of the species from different places, thus, suggesting a new chemotype of Lippia grata. Larvicidal tests were performed at concentrations of 100, 75, 50, 25, and 12.5 μg.mL−1 and the essential oil from the rainy season showed the best results, with LC50 of 22.79 μg.mL−1 and 35.36 μg.mL−1 against Ae. aegypti and Ae. albopictus, respectively; this result was better than other reports. In the rainy period, however, there was a greater variety of components, which led to a better larvicidal effect, possibly due to synergistic action with minor constituents. Total proteins, amylases, and acetylcholinesterase of both species were inhibited by the oils.

“…All these compounds have been reported in L. gracilis. [16,50,51] Comparing the three major compounds carvacrol, p-cymene and thymol in the four treatments, it was observed that as the p-cymene content decreased in the shaded treatments, carvacrol and thymol increased in full sun cultivation. Data from the literature reported that plants of the family Lamiaceae biosynthesize carvacrol and thymol from the oxidation of 1cymene, α-terpinene and γ-terpinene.…”

The objective of this study was to evaluate the effect of ChromatiNet on vegetative growth, total antioxidant capacity, phenolic and essential oils (EOs) composition of Lippia gracilis. The plants were cultivated under full sunlight, black, blue and red ChromatiNet. The flavonoid content and antioxidant capacity were quantified spectrophotometrically. The C‐glycosylflavone isomers (orientin and isoorientin) were isolated and identified by conventional spectroscopic techniques and measured using high‐performance liquid chromatography‐diode array detection. The EO was analysed by gas chromatography and gas chromatography‐mass spectrometry. Environment influenced growth, total antioxidant capacity and phytochemical levels. Shoot dry weight, thymol, carvacrol and (E)‐caryophyllene were favoured under red and black ChromatiNet. Root growth, EOs, caryophyllene oxide, p‐cymene, flavonoids, orientin and isoorientin were favoured in sunlight. Growth and accumulation of EOs, flavonoids and photosynthetic pigments increased under blue ChromatiNet. Therefore, Lippia gracilis plants have plasticity related to the spectral quality of light and it cultivate depends of the phytochemicals of interest.

“…Since P. serpens is a model species for studies on trypanosomatids, this result can be verified in parasites of the same genus known to cause serious diseases in large plant cultures such as P. leptovasorum, which causes coffee necrosis, P. staheli, which causes wilting in palm and coconut palms, and P. francai, which causes root puckering in manioc (Manihot esculenta) (Jaskowska et al, 2015). Due to the biodegradability and low toxicity of essential oils, studies on clarifying the potential action of essential oils in the control of pests that attack plant crops have been emphasized in recent years (Nizio et al, 2015;Sampaio, et al, 2016, Cruz et al, 2018, Melo et al, 2018, Silva et al, 2019. The chemical complexity of volatile oils is the factor responsible for the wide biological activity found, and for hindering the resistance process that occurs in microorganisms (Salem et al, 2018).…”

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