“…The essential oil from A. polystachya leaves grown in the southeast region of Brazil revealed a high content of carvone (80.71%) and limonene (14.65%) [ 14 ]. In addition, these studies validated the antimicrobial activity of A. polystachya oils against different human pathogens [ 10 , 11 , 12 , 13 , 14 ].…”

“…There are four reports from Argentina and one from Brazil where the chemical composition of the oils has been determined. Of the plants that grow in Argentina, the main constituents of the oils of the leaves of the species collected in the province of Cordova have been described as the monoterpenes α-tujone (83.56%), sabinene (4.61%), and limonene (1.62%) [10,11], while in species collected in the cities of Buenos Aires and Corrientes the predominant monoterpenes are carvone (83.5-84.4%), limonene (14.2-16.5%), and verbenone (1.58%) [12,13]. The essential oil from A. polystachya leaves grown in the southeast region of Brazil revealed a high content of carvone (80.71%) and limonene (14.65%) [14].…”

The aim of this study was to determine, first, the chemical composition of Aloysia polystachya (Griseb) Moldenke essential oil, from leaves harvested in central Chile; and second, its antioxidant and cytotoxic activity. Eight compounds were identified via gas chromatography–mass spectrometry (GC–MS) analyses, with the most representative being R-carvone (91.03%), R-limonene (4.10%), and dihydrocarvone (1.07%). For Aloysia polystachya essential oil, antioxidant assays (2,2-diphenyl-1-picrylhydrazyl (DPPH), H2O2, ferric reducing antioxidant power (FRAP), and total reactive antioxidant potential (TRAP)) showed good antioxidant activity compared to commercial antioxidant controls; and anti-proliferative assays against three human cancer cell lines (colon, HT-29; prostate, PC-3; and breast, MCF-7) determined an IC50 of 5.85, 6.74, and 9.53 µg/mL, and selectivity indices of 4.75, 4.12, and 2.92 for HT-29, PC-3, and MCF-7, respectively. We also report on assays with CCD 841 CoN (colon epithelial). Overall, results from this study may represent, in the near future, developments for natural-based cancer treatments.

“…In those species, essential oil supplementation increased digestibility, improved pancreatic enzymes’ activity, changed microbiota, impacted the absorption of amino acids in the intestines, and, consequently, feed conversion rate [ 27 – 29 ]. The supplementation also increases immunoglobulins levels and immune response [ 30 ], decreases specify pathogens concentrations in feces [ 31 , 32 ] and presented an insecticidal [ 33 ], acaricidal and antioxidant effects [ 34 ]. However, there is inconsistent data between other species, probably explained by the complexity of the essential oils’ molecules and differences among the many types of GIT [ 19 ].…”

Effects of a blend of essential oils in milk replacer on performance, rumen fermentation, blood parameters, and health scores of dairy heifers

et al. 2021

The aim of this study was to evaluate how the inclusion of a blend of essential oils in milk replacer (MR) affects different outcomes of dairy heifers. The outcomes evaluated: feed intake, performance, body development, blood cells and metabolites, insulin-like growth factor-1 (IGF-1), rumen fermentation, fecal scores, and respiratory scores. All outcomes were evaluated during pre-weaning (4–60 d of age), and carry-over effects during post-weaning (61–90 d of age) periods. The experimental units utilized were 29 newborn Holstein × Gyr crossbred dairy heifers, with genetic composition of 5/8 or more Holstein and 3/8 or less Gyr and body weight (BW) at birth of 32.2 ± 5.2 kg. Experimental units were assigned to either a control (CON, n = 15) or a blend of essential oil supplementation (BEO, n = 14) treatment, maintaining a balance of genetic composition. The BEO was supplemented in the MR with 1 g/d/calf of a blend of essential oils (Apex Calf, Adisseo, China) composed by plant extracts derived from anise, cinnamon, garlic, rosemary, and thyme. During the pre-weaning phase, all heifers were fed 5 L of MR/d reconstituted to 15% (dry matter basis), divided into two equal meals. Water and starter were provided ad libitum. During the post-weaning, animals received a maximum of 3 kg of starter/d, and ad libitum corn silage, divided into two meals. Feed intake, fecal and respiratory scores were evaluated daily. The BW was measured every three days, while body development was recorded weekly. Blood samples were collected on 0, 30, and 60 d of age for total blood cell count, weekly and on the weaning day to determinate ß-hydroxybutyrate, urea and glucose, and biweekly for IGF-1. Ruminal parameters (pH, volatile fatty acids, ammonia-N, and acetate:propionate proportion—C2:C3) were measured on days 14, 28, 42, 60, 74 and 90. A randomized complete block design with an interaction between treatment and week was the experimental method of choice to test the hypothesis of the BEO’s effect on all outcomes. An ANOVA procedure was used for continuous outcomes, and a non-parametric test was used for the ordered categorical outcomes, both adopting a CI = 95%. Results indicated that there was not enough evidence to accept the alternative hypothesis of the effect of BEO in MR on feed intake, performance, body development, and blood metabolites during both pre-weaning and post-weaning periods. However, results indicated that the inclusion of BEO in MR significantly affects the proportion of C2:C3 during pre- and post-weaning (P = 0.05). Similarly, the effect was significant for basophil (P ≤ 0.001), and platelet (P = 0.04) counts pre-weaning. The interaction between week and treatment was also significant for lymphocytes (P ≤ 0.001), revealing a cumulative effect. Lastly, fecal scores were also significant (P = 0.04) during pre-weaning, with lower values for BEO. The BEO contributed to ruminal manipulation in pre-weaning and carry-over effects in post-weaning, immunity improvement, and decreased morbidity of neonatal diarrhea in the pre-weaning phase.

“…All treatments were replicated six times, under controlled temperature (25 ± 1 °C) and relative humidity (60 ± 10%) in darkness. Mortality was checked daily and insects were considered dead when they showed no movement when touched with tweezers (Arena et al, 2020). After seven days the wafers were weighed again (final weight) to determine the amount of food consumed (FC).…”

In this exploratory study, the antifeedant activity of ethanolic extracts of nine plants native from central region of Argentina on Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae) was evaluated, looking for low environmental impact management alternatives. Adults of A. diaperinus were exposed to food treated with the extracts to assess whether feeding behaviour and survival were altered. None of the extracts affected adult survival. However, the extracts of Gaillardia megapotamica, Vernonanthura nudiflora, Baccharis artemisioides, Lithraea molleoides, and Ambrosia artemisiifolia had a strong antifeedant effect (92-96%). The other extracts evaluated slightly affected (50-55%) the food consumption. The extracts of G. megapotamica and B. artemisioides were administered with the food to the fifth larval stage to assess whether they affect survival, feeding behaviour, and weight of immature forms. The B. artemisioides extract generated a marked deterrent effect of feeding on the larvae (76%) during the first week of experimentation, although the effect weakened over time. On the other hand, G. megapotamica produced a moderate deterrent effect (41-74%) throughout the experiment. The extracts also affected weight, survival, and number of larval exuviae in relation to the control
