Atividade anti-helmíntica do extrato aquoso das folhas de Zanthoxylum rhoifolium Lam. (Rutaceae)

Abstract: ResumoO estudo avaliou a atividade anti-helmíntica do extrato aquoso das folhas de Zanthoxylum rhoifolium em dois experimentos. O teste in vitro utilizou cultivos de fezes de caprinos tratados com diferentes concentrações do extrato: (134,5 a 335,0 mg.mL -1). No teste in vivo, utilizaram-se 20 ovelhas: G1 tratado durante quatro dias (0,63 g.kg -1 PV); G2, mesma dose, por oito dias; G3, ivermectina (200 µg.kg -1 ); e G4, sem tratamento. In vitro, observou-se redução de larvas de Haemonchus, Trichostrongylus e O… Show more

“…This plant has been reported to have antimalarial, antinociceptive, antitumoral, and gastroprotective effects. The essential oil of its leaves and alkaloids isolated from the stem bark have antibacterial activity against gram-positive and -negative bacteria and antifungal activity against Aspergillus flavus, but no activity against Candida species was found (Gonzaga et al, 2003;Jullian et al, 2006;Silva et al, 2007;Boehme et al, 2008;Peneluc et al, 2009;Pereira et al, 2010;Freitas et al, 2011). Activity against Candida spp.…”

“…However, compounds that are active in vitro are not necessarily active to the same extent in vivo (Sangster and Gill, 1999). This divergence, which is relatively common in studies of new anthelmintic drugs against H. contortus, is due to factors related to the bioavailability and intrinsic pharmacology of the compound tested, such as its possible destruction or insolubility in the animal's rumen as well as additional protection of the worm in the abomasum (Peneluc et al, 2009;Buttle et al, 2011). This limitation should be taken into account and highlights the importance of pharmaceutical/pharmacokinetic studies for the industrial development of new anthelmintic products against H. contortus.…”

“…Os extratos metanol, clorofórmio e hexano de casca de Z. rhoifolium, assim como o alcaloide zantoxiline e o óleo essencial de folha e fruto apresentam atividade antimicrobiana frente aos micro-organismos: Staphylococcus aureus, Staphylococcus epidermidis, Micrococcus luteus, Klebsiella pneumoniae, Salmonella setubal e Escherichia coli (GONZAGA et al, 2003a;GONZAGA et al, 2003b). O extrato aquoso de folhas é ativo em teste in vitro na redução de nematodas intestinais (PENELUC et al, 2009). Alcaloides isolados das cascas do caule demonstraram atividade antiparasitária que varia de boa a moderada (BERTANI et al, 2005;JULLIAN et al, 2006;PENELUC et al, 2009), em outros estudos com a planta foi possível identificar atividade antinociceptiva, analgésica (PEREIRA et al, 2010), citotóxica (SILVA; FIGUEIREDO; YANO, 2007a), quimioterápica (SILVA; FIGUEIREDO; YANO, 2007b) e antitumoral (COSTA et al, 2010).…”
