“…predation activity was exclusively recorded during the nocturnal observations, when it was more difficult to register their presence. There is little information on the biology of neotropical species of Elateridae (Cruz et al 1997;Cruz 2008;Vanin et al 2008). It is known that the larvae of these insects, including the species of the genus Monocrepidius, are root and stem borers and adults feed on the leaves, buds, pollen, and nectar (Lima 1953).…”

“…In terms of ecological importance, Piper species have been considered as model due to the richness of species and diversity of interactions with herbivores. [16][17][18][19][20][21] In general, Piperaceae species can be easily propagated and the availability of data on taxonomy, molecular phylogeny, ecology and chemical composition provides the basis for multidisciplinary studies.Most of the phytochemical investigation has been addressed to determine major bioactive secondary metabolites and thus, Piperaceae species have shown to produce amides, pyrones, chromenes and lignoids. [22][23][24][25][26][27][28] Several Piper species are pioneer, and can be found in forest borders and for such reason they are also under risk of depletion by anthropic activities.…”

O perfil metabólito baseado na aplicação de análises multivariadas (análise de componentes principais, PCA) dos dados de espectrometria de massas com ionização electrospray (ESIMS) no modo positivo e de ressonância magnética nuclear (RMN) do 1 H de extratos brutos de espécies de Piper destacou algumas espécies caracterizadas pela produção de lignanas (P. solmsianum, P. truncatum e P. cernuum), neolignanas (P. regnellii) e cromenos (P. gaudichaudianum). Análises específicas em conjunto de espécies caracterizadas morfologicamente por apresentarem inflorescências pêndulas e globosas (P. caldense, P. carniconnectivum, P. bowiei e P. permucronatum) ou em espécies que produzem amidas indicaram o potencial mais significativo para tais análises como critério para estudos fitoquímicos posteriores. Análises intraespecíficas de plântulas das espécies P. solmsianum, P. regnellii e P. gaudichaudianum indicaram uma composição química nas folhas baseada na presença dos fenilpropanóides dilapiol e apiol, diferentemente do que produzem as plantas adultas. No caso das espécies que produzem amidas, a composição apresentou-se relativamente constante independentemente do estágio de desenvolvimento.The metabolomic profiling based on the application of multivariate analysis (principal component analysis, PCA) of positive mode electrospray ionization mass spectrometric (ESIMS) and 1 H nuclear magnetic resonance (NMR) data of crude extracts highlighted some species characterized by lignans (P. solmsianum, P. truncatum and P. cernuum), neolignans (P. regnellii) and chromenes (P. gaudichaudianum). A specific analysis focusing on species having pendant and globular inflorescences (P. caldense, P. carniconnectivum, P. bowiei and P. permucronatum) or amides-producing species indicated higher potential of the methodology in determining similarities and establishing priorities for further phytochemical investigation. Such intraspecific analysis applied to analyzed seedling leaves of the P. solmsianum, P. regnellii and P. gaudichaudianum species revealed the production of dillapiole and apiole instead of lignans, neolignans or prenylated benzoic acid, produced by the adult leaves, respectively. In case of amides-producing species, a similar profile was observed regardless the developmental stage.Keywords: Piperaceae, principal component analysis, secondary metabolites, fingerprinting Chemometric Analysis of ESIMS and NMR Data from Piper Species J. Braz. Chem. Soc. 2372 IntroductionThe knowledge on secondary chemistry of tropical plant species is limited to approximately 5-10% of the total species described so far. In fact, this limited study indicates the potential for finding novel lead compounds from tropical biodiversity. Despite the availability of high throughput technology platforms to detect bioactive compounds, the process of cataloguing their composition possesses a significant challenge since it still involves largely the isolation and spectroscopic characterization of individual components. Additionally, the determination of a m...

“…Hence, even though a shrub species' abundance may have some influence on the species richness of its associated herbivores , this does not appear to be a strong driver in the herbivore communities of this study. Vanin et al (2008) reported "remarkably narrow feeding preferences" for Piper herbivores from both field and lab data. Similarly, host plant specificity of caterpillar species found on Piper plants in this study was pronouncedly higher than of those found on Asteraceae.…”
