| Los géneros Piper y Lepianthes han sido empleados como fuente de insecticidas y en la medicina natural. Son conocidas las propiedades antifúngica, insecticida, antialimentaria, estimulante, bactericida y citotóxica de muchos de sus extractos. El objetivo de este trabajo fue establecer las potencialidades de tres aceites esenciales de especies de estos géneros como candidatos para el desarrollo de productos con actividad plaguicida y antitumoral. Los aceites esenciales de P. auritum (CA1), P. aduncum subsp. ossanum (PAO1) y L. umbellata (LU1) fueron obtenidos por hidrodestilación empleando un equipo Clevenger y se evaluaron frente a Artemia salina, organismo indicador de actividad plaguicida y antitumoral. La actividad antibacteriana de los aceites... |

| Setenta e oito acessos de pimenta-do-reino, incluindo algumas espécies silvestres foram submetidas à análise eletroforética de isoenzimas em gel de poliacrilamida, visando distinguir diferenças fenotípicas que auxiliem na discriminação e seleção dos acessos. Foram utilizados os sistemas enzimáticos SKDH, GOT, ACP, ACO, PGI, FUM, 6PGDH e G6PDH. O polimorfismo de isoenzimas foi avaliado pelo número de alozimas com diferentes mobilidades por sistema enzimático, pelas freqüências de alozimas dentro de cada sistema enzimático em relação ao total de bandas do sistema e pela análise da similaridade genética, com base na ausência e presença de bandas. Todos os sistemas enzimáticos utilizados tiveram boa resolução e definição de bandas, com ênfase para SKDH, 6PGDH,... |

| Piperaceae species have been placed among the basal angiosperm and are adapted to a variety of habitats including moist forests, secondary vegetation and dry high lands. The major anatomical/morphology features are of small trees, vines, and shrubs for Piper species, while the epiphytic and succulent characteristics are predominant forms among Peperomia species. Their secondary chemistry can be mostly represented by amides, phenylpropanoids/lignoids, and chromenes in addition to a phletoria of biosynthetically mixed-origin secondary compounds. Although several amides and lignans are known as insecticides, several phytophagous insects, among which some considered pests of economic importance, have been observed feeding vigorously on Piperaceae species.... |

| 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... |

| Piper in the Philippine Islands is reviewed. Fifteen climbing species are recognized (many fewer than in previous treatments) and distinguished in a key. Most are widely distributed through Malesia, with ranges that end eastwards in the Solomon Islands or Australia. Piper myrmecophilum, the only taxon accepted as endemic to the Philippines, is ant-associated. Piper celtidiforme, once thought endemic, also occurs in New Guinea and the Solomons. The five shrubby Piper species in the Philippines are briefly described. |

| Eleven climbing species of Piper in the Solomon Islands are recognized: P. abbreviatum, P. betle, P. bosnicanum, P. caninum, P. celtidiforme, P. fragile, P. insectifugum (syn. P. austrocaledonicum), P. interruptum, P. macropiper, P. majusculum, and, as the only endemic, P. sclerophloeum, for which a description is provided. |

| Ethanol, methanol and water extracts representing mostly native plant species found in the Amazon region were prepared, respectively, by maceration, continuous liquid-solid extraction and infusion, followed by evaporation and freeze-drying. The freeze-dried extracts were tested for lethality toward Aedes aegypti larvae at test concentrations of 500 mg / mL. In general, methanol extracts exhibited the greatest larvicidal activity. The following 7 methanol extracts of (the parts of) the indicated plant species were the most active, resulting in 100% mortality in A. aegypti larvae: Tapura amazonica Poepp. (root), Piper aduncum L. (leaf and root), P. tuberculatum Jacq. (leaf, fruit and branch). and Simaba polyphylla (Cavalcante) W.W. Thomas (branch). |
