Ação dos extratos de favela (Cnidoscolus phyllacanthus), catingueira (Caesalpinia pyramidalis) e nim (Azadiracta indica) sobre bactérias isoladas de cabras de aptidão leiteira

Abstract

RESUMO
 No Nordeste brasileiro, cuja vegetação predominante é Caatinga, muitas plantas nativas ou exóticas são potencialmente ricas em propriedades curativas, porém pouco exploradas ainda pela ciência. O trabalho foi realizado durante agosto de 2011 a junho de 2012, onde foram coletadas amostras bacterianas dos tetos dos animais através de swabs estéreis. Isolados e devidamente identificados, os microrganismos foram sujeitos a antibiogramas com os meios alternativos, controles positivos e negativo através da técnica de difusão em Ágar de poço. O objetivo do trabalho foi avaliar a ação dos extratos de Favela (Cnidoscolus phyllacanthus), Catingueira (Caesalpinia pyramidalis) e Nim (Azadiracta indica) sobre bactérias isoladas de tetos de cabras no assentamento de Cordão de Sombra no Município de Mossoró-RN.
 
 ABSTRACT
 In Northeast Brazil, whose predominant vegetation is Caatinga, many native or exotic plants are potentially rich in healing properties, but little explored yet by science. The work was conducted during August 2011 to June 2012, where bacterial samples were collected from the teats of animals through sterile swabs. Once isolated and properly identified, the microorganisms were subjected to antibiograms with alternative means, positive and negative controls through the well agar diffusion technique. The objective of the work was to evaluate the action of extracts of Favela (Cnidoscolus phyllacanthus), Catingueira (Caesalpinia pyramidalis) and Neem (Azadiracta indica) on bacteria isolated from teats of goats in the settlement Cordão de Sombra in the Municipality of Mossoró-RN.

Chemical Composition and Biological Activities of the Cnidoscolus quercifolis: A Review

“…In the extracts of the seeds and the pressed cake, several phenolic compounds were observed, including syringic acid (1), ellagic acid (2), catechin (3), quercetin (4), vanillin ( 5), eugenol (6), vanillic acid (7), and, especially, gallic acid (8) [46]. Alves et al [48] investigated the chemical composition of essential oils from various parts of C. quercifolius (leaves, flowers and bark) obtained by hydrodistillation and, using GC-MS, identified 31 compounds in the leaves (9-11, 39-66), 30 compounds in the flowers (10,12,13,42,43,44,46,49,52,54,55,58,60,(67)(68)(69)(70)(71)(72)(73)(74)(75)(76)(77)(78)(79)(80)(81)(82)(83), and 18 compounds in the stem bark (15,41,64,(84)(85)(86)(87)(88)(89)(90)(91)(92)(93)(94)(95)…”

“…The hexanic and methanolic extracts, on the other hand, showed low antibacterial capacity compared to the isolated compounds, both in MIC (5.0 mg/mL −1 , both extracts) and in MBC (>10 mg/mL −1 , both extracts). Carvalho et al [68] investigated the hydroalcoholic extract of leaves against 18 bacteria isolated from the teats of goat; however, among the strains analyzed, the extract was effective only on Staphylococcus sp. negative coagulase.…”
