| 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... |

| 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). |

| A study about the species of Piperaceae that are consumed by a colony of Carollia perspicillata (Linnaeus, 1758) in Parque Municipal Arthur Thomas (82,72 ha) was carried out. Five available species of Piperaceae were found in the park: Piper aduncum Linnaeus, Piper amalago (Jacq.) Yuncker, Piper crassinervium H.B.K., Piper gaudichaudianum Kunth and Piper sp. C. perspicillata fed on all of these species. During the spring, the most abundant item was P. amalago, but the consumption of P. aduncum was the highest. At the beginning of the summer, P. crassinervium was the most abundant and most consumed item. At the end of the summer and during the fall, P. gaudichaudianum was the most abundant and consumed item, even in May, when P. amalago was the most... |

| Foi avaliada, no presente estudo, a toxicidade de amidas análogas à piperina utilizando-se larvas de 3º instar de Ascia monuste orseis Godart e Spodoptera frugiperda (J.E. Smith). Os bioensaios consistiram na aplicação tópica de 0.5 µl das seguintes amidas: N-isopentil-(3,4-metilenodioxifenil)-amida, N-isopropil-(3,4-metilenodioxifenil)-amida, N-hexil-3-(3,4-metilenodioxifenil)-amida e butóxido de piperonila. Os valores de DL50 (mg i.a./ mg larva) das amidas N-isopropil e N-hexil para A. monuste foram 0.278 e 0.004, respectivamente; para S. frugiperda foram: 1.359 e 0.613, respectivamente. O maior valor das inclinações das curvas de dose-resposta dentre os compostos, para ambas as espécies de inseto foi obtido para N-isopropil, o que indica maior... |
