O óleo essencial de Schinus terebinthifolius foi analisado por CG e CG-EM. α-Fencheno, limoneno, β-pineno, α-felandreno e β-isosilvestreno representam aproximadamente 80% da composição do óleo. A toxicidade na reprodução de ratos Wistar machos foi avaliada. Não foram observadas mudanças na massa dos órgãos reprodutivos, no número e morfologia dos espermatozoides, nas taxas de reprodução e na massa corporal dos ratos machos após tratamento com o óleo essencial de S. terebinthifolius.The essential oil of Schinus terebinthifolius (Anacardiaceae) was analyzed by GC and GC-MS. α-Fenchene, limonene, β-pinene, α-phellandrene, and β-isosylvestrene represent about 80% of the oil composition. The reproductive toxicity of the essential oil in Wistar male rats was evaluated. No changes were observed in the mass of the reproductive organs, number and morphology of spermatozoa, reproductive rates, and the body mass of offspring of male rats after treatment with the essential oil of S. terebinthifolius.

The tea of flowers of M. caesalpiniifolia promotes hypotension and tachycardia, whereas ethanolic extract (MC-EtOH) promotes hypotension and bradycardia involving the participation of the muscarinic and ganglionic pathways, as well as vasorelaxant action involving the Ca(2+) influx inhibition blockade.

A atividade anti-helmíntica dos extratos aquoso e etanólico do fruto da Morinda citrifolia (noni) foi avaliada em aves poedeiras naturalmente infectadas por Ascaridia galli. A atividade anti-helmíntica in vitro foi determinada em parasitos adultos. O extrato aquoso e etanólico foram testados nas seguintes concentrações: 1,69; 3,37; 6,74; 13,48 AbstractThe anthelmintic activity of aqueous and ethanolic extracts of Morinda citrifolia fruit (noni) was evaluated in chicken naturally infected by Ascaridia galli. The anthelmintic activity in vitro was determined in adult parasites. The aqueous and ethanolic extracts were used in the following concentrations: 1.69; 3.37; 6.74; 13.48 e 26.96 mg.mL -1 and 4.17; 8.34; 16.68; 33.36 and 66.72 mg.mL -1 , respectively. The anthelmintic activity in vivo was determined by the administration of 10 mL.kg -1 of the aqueous (50.1 mg.mL -1 ) and ethanolic (24.6 mg.mL -1 ) extracts during three consecutive days. Later the chickens were euthanized and necropsy was performed in order to count the remaining helminths. The data were analyzed by the Student-Newman-Keuls test. In the concentrations of 13.48 and 26.96 mg.mL -1 , the aqueous extract demonstrated mortality of 46.67 and 50%, respectively, there was a significative difference from the negative control (P < 0.05). The ethanolic extract presented statistical difference from the negative control (diluent) (P < 0.05) for the concentrations of 33.36 and 66.72 mg.mL -1 , expressed by a mortality rate of 66.67 and 76.67%, respectively. In the in vivo test, the aqueous extract of noni fruit showed 27.08% of elimination, deferring statistically from the control group. There was no statistical difference between the ethanolic extract treatments and the control (P > 0.05). It follows that the anthelmintic activity of noni fruit test showed satisfactory results in vitro, there is a need for studies in higher concentrations in the in vivo test.

Estudou-se a atividade anti-helmíntica das plantas; Allium sativum, Punica granatum, Tynnanthus fasciculatus e Cocos nucifera. Foram utilizados 70 frangos infectados naturalmente com Heterakis gallinarum, divididos em grupos de dez animais, com um controle positivo (20) e um negativo (10). Administraram-se as plantas na forma de extrato aquoso e suco por gavage e trituradas incorporadas à ração nas doses de 2, 3 e 10g kg-1 dia-1, durante três dias consecutivos. Os resultados foram avaliados através de teste não. O A. sativum, P. granatum, T. fasciculatus e C. nucifera eliminaram: 6,70; 4,12; 1,25 e 0,22% , respectivamente. Os percentuais de eliminação do A. sativum e do T. fasciculatus, corresponderam respectivamente a 1/4 e 1/6 do controle positivo, sendo o C. nucifera e o P. granatum semelhantes ao controle negativo. Desta forma, as plantas nas doses empregadas não apresentaram atividade significativa (P<0,05) sobre o helminto H. gallinarum .
