“…In Brazil, it is represented in the Caatinga, Cerrado, Atlantic and Amazon Forests, in the latter it is known only from Mount Roraima (Trelease & Yuncker 1950, Yuncker 1974, Steyermark & CallejasPosada 2003. According to Guimarães & Giordano (2004) and Monteiro & Guimarães (2008), the species occurs in montane areas of Ceará (Serra do Baturité) and high-montane forests of Rio de Janeiro (Parque Nacional do Itatiaia), respectively. The habitat of the study area is consistent with indications of Trelease & Yuncker (1950) and Steyermark & Callejas-Posada (2003), for Colombia and Venezuela, where the species can be found in areas of tepui and mountain ranges.…”

-(Synopsis of the genus Peperomia Ruiz & Pav. (Piperaceae) in Roraima State, Brazil). Peperomia is the second most diverse genus of Piperaceae, with an estimated 1,600 species and a pantropical distribution. This work aims to present a taxonomic synopsis of the genus in the State of Roraima, in the extreme north of the Brazilian Amazon forest and belonging to the central-south portion of the Guayana Shield. Based on collecting expeditions and analysis of specimens in various herbaria, 23 taxa were recognized, with two new records for the State and one of them, a new record for Brazil. The taxa are differentiated mainly by phyllotaxis, shape and size of their leaves, in addition to habit and fruits. They have been found in areas of lowland, submontane, montane, tepui and floodplain (várzea) forests and mostly show a distribution restricted to the Neotropics. Some species in the state are presently known exclusively from Mount Roraima, and restricted to a few specimens. Keywords: Amazon Forest, Guayana Shield, new records, Piperales, Tepui RESUMO -(Sinopse do gênero Peperomia Ruiz & Pav. (Piperaceae) no Estado de Roraima, Brasil). Peperomia Ruiz & Pav. é o segundo gênero mais diverso de Piperaceae, com aproximadamente 1.600 especies que estão distribuídas na região pantropical. Este trabalho tem o objetivo de apresentar uma sinopse taxonômica do gênero no Estado de Roraima, extremo norte da Floresta Amazônica brasileira, pertencente ao centro-sul do Escudo da Guiana. Com base em expedições e análise de espécimens de vários herbários, foram reconhecidos 23 táxons, dois são novos registros no Estado e um deles é um novo registro para o Brasil. As espécies se diferenciam principalmente pela filotaxia, forma e tamanho das folhas, além do hábito e frutos. Os táxons foram encontrados em áreas de terras baixas, submontanas, montanas, tepui e planícies inundáveis (várzea) e na maioria possui distribuição Neotropical. Algumas espécies no Estado são conhecidas exclusivamente no Monte Roraima e restringidas a poucos espécimens.

Recebido em 30/3/12; aceito em 24/7/12; publicado na web em 26/10/12 This manuscript describes an update review with up to 285 references concerning the occurrence of amides from a variety of species of the genus Piper (Piperaceae). Besides addressing occurrence, this review also describes the biological activities attributed to extracts and pure compounds, a compiled 13 C NMR data set, the main correlations between structural and NMR spectroscopic data of these compounds, and employment of hyphened techniques such as LC-MS, GC-MS and NMR for analysis of amides from biological samples and crude Piper extracts. Keywords: Piper;13 C NMR compilation; amides. INTRODUCTIONPiperaceae is one of the largest families among the basal Angiosperms, with approximately 3,000 species described to date. 1The family is currently divided into five genera: Macropiper, Zippelia, Piper, Peperomia and Manekia, 2 consisting of a wide variety of species found commonly around the world. Piper, Peperomia and Manekia occur in Brazil, mainly in the Amazonian and Atlantic forests. 3 Piper is the largest genus of this family, including more than 1,000 species, and can also be considered the largest genus of the basal angiosperms. 4 Amides are the major constituents of several species of Piper. Currently, they can be considered alkaloids in accordance with the modern definition by Pelletier.5 Natural amides can be classified as open-chain alkamides, aristolactams, 4,5-dioxoaporphines, ceramides, amides with pyrrolidine, piperidone and piperidine groups, cyclobutanamides and cyclohexanamides. The term piperamide is restricted to describe all compounds carrying an aromatic group and an amide group.In 1997, a review of this genus was published 6 dealing with chemical distribution and biological activities of amides. In the present review, an update with new chemical constituents of this genus is described and a compilation of 13 C NMR data and biological activities of these compounds are provided. Piper SPECIES, TRADITIONAL USES AND BIOLOGICAL ACTIVITIESDespite the large number of species of Piper, the use of these plants in folk medicine remains limited. One of the most well-known Piper Brazilian medicinal plants is P. corcovadensis, commonly found in North and Northeast regions, and popularly known as "João-brandinho". The leaves of this plant are used for the treatment of rheumatism in the form of poultice and infusions as well for flu and cough. In the Southeast region, the roots and branches of this specie are chewed to relieve toothache due to its anesthetic action on the mucous membrane. 7 In China, the use of leaves of P. futokasura is recommended in the treatment of cardiac arrhythmias and asthma. In Jamaica, stomach pains are treated with an infusion of leaves from P. aduncum and P. hispidum. Leaves from P. amalago are also employed in Mexico and Brazil for stomach pains and for the treatment of various infections. 8 Leaves and stems of P. marginatum and P. tuberculatum are used in Brazil, especially in Paraíba State (Brazil) agains...

“…The genera that occur in Brazil (Manekia, Peperomia and Piper) can be easily distinguished by habit. Manekia comprises climbing vines (Monteiro & Guimarães 2009), Peperomia comprises herbaceous (terrestrial or epiphytic) species (Monteiro & Guimarães 2008), while Piper includes tree and shrub species (Monteiro & Guimarães 2009). …”

The conservation and management of the Atlantic Forest depends upon reliable knowledge about how many and which species this biome shelters. Floristic inventories have an important role in this process, especially when conducted in poorly known remnants, with a high conservation priority. This paper presents the study of the genus Piper (Piperaceae) in the Mata das Flores State Park, Castelo municipality, Espírito Santo state (ES). The study was based on the analysis of dried specimens, as well as those observed in the field, from February 2012 to August 2015. Twenty species of piper were identified. Amongst these species, Piper dilatatum, P. macedoi and P. piliovarium were recorded for the first time for the Espírito Santo state. Piper bicorne, an endemic species from ES and known only for the Santa Leopoldina municipality, had its geographical distribution expanded to the Castelo municipality. Most of the Piper species in the MFSP occur in valleys, and they are commonly found near watercourses. This is worrying given that these areas are just the most affected by the expansion of the rural and urban areas that surround the Park. Key words: Atlantic Forest, flora, taxonomy. ResumoA conservação e o manejo da Floresta Atlântica dependem de conhecimento confiável sobre quantas e quais espécies este bioma abriga. Inventários florísticos têm um importante papel neste processo, especialmente quando conduzidos em remanescentes pouco conhecidos com alta prioridade de conservação. Este trabalho apresenta o estudo realizado no gênero Piper (Piperaceae) no Parque Estadual de Mata das Flores, município de Castelo, estado do Espírito Santo (ES). O estudo foi baseado na análise de espécimes herborizados, assim como observados a campo, em expedições realizadas de fevereiro de 2012 a agosto de 2015. Vinte espécies de Piper foram identificadas. Destas, Piper dilatatum, P. macedoi e P. piliovarium foram registradas pela primeira vez para o estado do Espírito Santo. Piper bicorne, espécie endêmica do ES e conhecida apenas para o Município de Santa Leopoldina, teve a sua distribuição geográfica expandida para o Município de Castelo. A maior parte das espécies de Piper no PEMF ocorre nas áreas de vale, e frequentemente próximas a cursos d'água. Tal fato gera preocupação em relação à conservação destas espécies, dado que estas áreas são justamente as mais afetadas pela expansão das áreas urbana e rural do entorno. Palavras-chave: Floresta Atlântica, flora, taxonomia.
