| ABSTRACT The strategies to control the cattle tick, Rhipicephalus microplus are based mainly on the use of synthetic pesticides. However, the emergence, establishment, and development of resistance of ticks is rendering the main chemical groups ineffective. Finding new molecules to effectively control infestations by R. microplus is necessary to maintain the productivity of cattle herds, particularly of taurine breeds established in equatorial and tropical regions of the world. Ethanol extracts from the leaves, stems, and fruits of Piper tuberculatum were evaluated in bioassays at concentrations of 50, 25, 12.50, 6.25, 3.12 and 1.56 mg mL-1. The concentrations lethal to 50% of the individuals (LC50) of tick larvae after 24 hours of exposure were 3.62, 3.99... |

| Abstract Piper betle L., is an evergreen perennial creeper belonging to family Piperaceae and is known to possess numerous medicinal properties. Current study focuses on evaluating antioxidant and antimicrobial potential of betel leaf. For the present study, distilled water, hexane, acetone and ethanolic extracts of two varieties of betel leaves: Meetha paan and Banarasi paan were used. Biochemical tests such as proximate analysis (moisture, ash, protein, lipids, minerals viz., sodium and potassium), antioxidant activity tests (DPPH radical scavenging activity, total phenolics, ascorbic acid, reducing power) and antimicrobial test (antibacterial and antifungal susceptibility test) against four pathogens viz., B. subtilis, E. coli, A. niger and S.... |

| Este trabalho teve como objetivo avaliar o potencial inseticida do extrato acetônico das folhas de Piper hispidum Kunth sobre Hypothenemus hampei (Ferrari, 1867) em aplicação tópica, superfície contaminada e efeito de repelência. Adotou-se as diluições de 25,0; 5,0; 0,1; 0,02; 0,004 e 0,0008 mg mL-1 para exposição em superfície contaminada e aplicação tópica. No teste de repelência, utilizou-se a diluição 0,5 mg mL-1 do extrato. As avaliações foram realizadas nas 48 horas após a exposição ao extrato. Na exposição em superfície contaminada, obteve-se 100% de mortalidade, na diluição 25,0 mg mL-1, e de 50 a 80% nas diluições 0,004 a 5,0 mg mL-1, enquanto 0,0008 mg mL-1 e o controle resultaram em apenas 5% de mortalidade. Na aplicação tópica, atingiu-se 60 a... |

| The growth of fungi during pre - and postharvest of fruits may cause spoilage and result in a reduction in quality and quantity. The aim of the present work was to investigate the efficacy of four extracts (n-hexane, dichlorometane, ethyl acetate, and methanol) and the essential oil of Piper auritum Kunth and P. holtonii C. DC. on the growth inhibition of three important postharvest pathogens of fruits (Colletotrichum acutatum, C. gloeosporioides, and Botryodiplodia theobromae). The in vitro antifungal activity was assayed following the poisoned food technique. The results showed that both n-hexane extract (HE) as essential oil (EO) displayed a relative good control against the three pathogens, being the originating materials of P. holtonii the most... |

| The cytotoxicity of the dichloromethane crude extract (DCE), obtained from the aerial parts of Pothomorphe umbellata (L.) Miq (Piperaceae), was evaluated against nine human cancer cell lines (MCF-7, NCI-ADR/RES, OVCAR-3, PC-3, HT-29, NCI-H460, 786-O, UACC-62, K-562). The DCE presented antiproliferative activity with good potency against all cell lines at low concentrations (between 4.0 and 9.5 µg/mL) and with selectivity (1.55 µg/mL) for the leukemia cell line (K-652). DCE (100, 200, 300 and 400 mg/kg, ip) was also evaluated in the Ehrlich ascites tumor model. Both the survival number and the life span of the animals that died increased by at least 45 and 50%, respectively (8 animals per group), demonstrating P. umbellata extract potential anticancer... |

| Este trabalho teve como objetivos determinar as principais espécies de abelhas visitantes de inflorescências de pimenta longa, Piper hispidinervum (C.DC.), sua abundância e freqüência relativas. Além disso, verificaram-se também os seus horários de visitação e a influência de fatores climáticos na variação da abundância dessas espécies. As coletas foram realizadas na área experimental da Embrapa Acre, com as amostragens efetuadas com auxílio de um aspirador de boca durante o período de julho de 1999 a junho de 2000, em um plantio experimental de pimenta longa, com aproximadamente 0,5 ha. As inflorescências de pimenta longa foram visitadas por abelhas durante todo ano, sendo coletados 2555 indivíduos pertencentes a 20 espécies de abelhas, das quais... |

| The essential oil from Piper solmsianum leaves and its major compound (sarisan) were tested to verify their influences upon mice behaviour. The essential oil was obtained by hydrodistillation in a modified Clevenger extractor and analysed by GC/ MS. This analysis revealed in the oil the presence of monoterpenes, sesquiterpenes and of arylpropanoids. The compound sarisan, a myristicin analogue, was isolated from the oil to perform the pharmacological tests. Emulsions of the oil and of sarisan (5.0 and 10.0% v/v) were used in the tests. Pentobarbital (30 mg/ kg s.c.) or diazepam (2.5 mg/ kg s.c.) were tested as standard drugs to verify depressant or anxiolytic effects, respectively. Both essential oil and sarisan showed to have exciting and depressant... |

| ABSTRACT Ottonia martiana is a plant popularly known in Brazil by the use for toothache. Ethanolic extract (EE), hexane fraction (HF), dichloromethane fraction (DF) and piperovatine obtained from O. martiana were assayed in vitro and in vivo. The acute toxicity of EE was determined, and LD50 values of 164.5 and 65.0 mg/kg by the oral and intraperitoneal routes, respectively, indicated a high toxicity for EE in vivo, explaining its popular use by topical administration only. A local anesthetic-like effect of EE and its fractions was observed in experimental models using pain induction, and such effect involved an analgesic action. The antimycobacterial activity of EE, HF, DF and piperovatine was evaluated against Mycobacterium tuberculosis H37Rv ATCC 27924.... |

| ABSTRACT Piperaceae species can be found worldwide in tropical and subtropical areas and many of them have been used for centuries in traditional folk medicine and in culinary. In Brazil, species of Piperaceae are commonly used in some communities as local anesthetic and analgesic. Countrified communities have known some species of the genus Ottonia as "anestesia" and it is a common habit of chewing leaves and roots of Ottonia species to relief toothache. The purpose of this study is to report our findings on new molecules entities obtained from the roots of Ottonia anisum Spreng, in which local anesthetic activity (sensory blockage) is demonstrated for the first time in vivo guinea pig model. Phytochemical investigation led to the isolation of three... |
