“…Their activity is probably due to their ability to complex with extracellular and soluble proteins and to complex with bacterial cell walls (Cowan, 1999). More lipophilic flavonoids may also disrupt microbial membranes (Tsuchiya et al, 1996).…”

“…De acordo com Tsuchiya et al (1996), essas substâncias podem agir se ligando a proteínas extracelulares e paredes celulares de bactérias, inativando-as. A bioatividade sobre insetos está atribuída à capacidade dos taninos em se ligar às proteínas, dificultando a digestão (Mairesse, 2005).…”

O objetivo deste trabalho foi avaliar o efeito de extratos vegetais aquosos de jambolão, Syzygium cumini (L.) Skeels (Myrtaceae), mamona, Ricinus communis (L.) (Euphorbiaceae), uva-do-japão, Hovenia dulcis (Thumberg) (Rhamnaceae) e urucum (Bixa orellana (L.) (Bixaceae), na concentração de 10%, sobre Bacillus thuringiensis subesp. kurstaki(Btk) e sobre Anticarsia gemmatalis (Lepidoptera: Erebidae) e a associação destes sobre A. gemmatalis, em condições de laboratório. Os tratamentos constaram dos extratos aquosos e Btk isoladamente e a mistura de cada extrato com Btk. Estes foram incubados em agitador horizontal (30 ± 2°C, 150 rpm por 2 h) e, em seguida, aplicados sobre cubos de dieta artificial para A. gemmatalis, em placas de Petri. Como testemunha utilizou-se água destilada esterilizada. Cada tratamento constou de 4 placas de Petri (repetição), com 25 lagartas de segundo ínstar cada. Estas foram acondicionadas em câmara climatizada (27 ± 2°C umidade relativa 70 ± 10% e fotofase 14 h), avaliando-se a mortalidade após 24, 48 e 72 h. Também foram avaliados o percentual de empupamento e o peso das pupas dos insetos sobreviventes. Nenhum dos extratos apresentou efeito inseticida para A. gemmatalis e efeito negativo para os cristais de Btk. A mortalidade acumulada causada pelos extratos de uva-do-japão, jambolão, urucum e mamona foram, respectivamente, de 54,73; 46,09; 47,19 e 65,73%; diferindo significativamente da testemunha (95,74%). O peso médio das pupas não diferiu significativamente entre os tratamentos. A associação dos extratos de uva-do-japão, colorau e mamona com Btk provocou mortalidade acumulada de 100% em A. gemmatalis.

“…[16] Flavonoids have been reported to have both antibacterial and antifungal activities. [18] Tannin from Dichrostachys cinerea root bark possesses antibacterial activities against S. aureus, E. coli and P. aeruginosa. [19] The bark extract was found to be containing tannin glycosides, alkaloids, steroids and Flavonoids which are biologically active.…”

a b s t r a c tIn-vitro antibacterial potential of apical, meddle and mature stem bark was assayed by employing the agar-well diffusion method against three gram '+'ve bacteria Bacillus subtilis, Staphylococcus aureus, and Micrococcus sp. and five Gram '-'ve bacteria Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoneae, Salmonella typhi, and Proteus mirabilis. the extract of apical bark was effective than the inner bark and mature outer bark in controlling the growth of all bacteria. the bacterium Salmonella typhi was most sensitive than other bacterial species. Preliminary phytochemical analysis revealed the presence of alkaloids, glycosides, flavonoids, flavanols, phenols, saponins and terpenoids. The concentrations secondary metabolites was found higher in the apical stem bark than the inner and mature outer stem bark.
