“…As can be observed from our findings, as well as from other analysis on essential oil from Piper species, [10][11][12][13]15,16 there is a notable tendency of those plants to biosynthesize sesquiterpenes, independent of their natural habitats. …”

“…Previous studies on leaf essential oils of what seems to be three varieties of P. arboreum have been reported and significant differences were found in their chemical compositions, although all them were dominated by sesquiterpenes. 10,11,15 The leaf essential oil of P. arboreum Aublet var. latifolium (C.DC) Yuncker from Rondônia, was characterized by an higher content of germacrene D (72.87%), 10 while in the leaf oil of P. arboreum var.…”

“…[2][3][4][5][6][7][8] Many Piper species are aromatic and as a consequence the chemical composition of the essential oils of several of them has been the subject of incessant studies, revealing a diverse range of volatile components, including monoterpenes, sesquiterpenes, arylpropanoids, aldehydes, ketones and long chain alcohols. [9][10][11][12][13][14][15][16] Pursuing the determination of the chemical composition of essential oils from aromatic and medicinal plants from Northeast of Brazil flora, especially from the State of Ceará, we are reporting now the results of the investigation of four Piper species: P. dilatatum L.C. Rich, P. arboreum Aubl., P. tuberculatum Jacq.…”

Os óleos essenciais obtidos por hidrodestilação das folhas de quatro espécies de Piper (P. arboreum, P. crassinervium, P. dilatatum and P. tuberculatum), coletadas no estado do Ceará, foram analisados por CG-EM. Os rendimentos dos óleos, calculados sobre o peso do material fresco, variaram entre 0,03 -0,11% (p/p). Os óleos foram caracterizados pela presença de mono-e sesquiterpenos, exceto o óleo de P. arboreum, no qual foram identificados apenas sesquiterpenos. β-Elemeno (0,58-3,03%), (E)-cariofileno (2,71-37,78%), germacreno D (3,43-11,81%), biciclogermacreno (2,83-25,07%) e δ-cadineno (0,52-2,44%) foram detectados em todas as amostras analisadas. Os monoterpenos majoritários identificados foram α-pineno (11,27%), β-pineno (20,01%), 1,8-cineol (10,81%) e linalol (28,61%) para P. crassinervium, e α-felandreno (22,53%) e ∆-3-careno (10,20%) para P. dilatatum. Biciclogermacreno (25,03 e 25,07%) para P. arboreum e P. dilatatum, (E)-nerolidol (11,12%) para P. arboreum, germacreno D (11,81%) para P. tuberculatum e (E)-cariofileno (10,26 e 37,78%) para P. dilatatum e P. tuberculatum, foram os principais sesquiterpenos. Este trabalho descreve, pela primeira vez, a composição química dos óleos essenciais de P. crassinervium e P. tuberculatum.The essential oils, obtained by hydrodistillation, from leaf samples of four Piper species (P. arboreum, P. crassinervium, P. dilatatum and P. tuberculatum), harvested at the State of Ceará, were analyzed by GC-MS. The oil yields ranged from 0.03 to 0.11% (w/w), on fresh weight basis. The oils were characterized by mono-and sesquiterpenes, except the oil of P. arboreum to which only sesquiterpenes were identified. β-Elemene (0.58-3.03%), (E)-caryophyllene (2.71-37.78%), germacrene D (3.43-11.81%), bicyclogermacrene (2.83 and 25.07%) and δ-cadinene (0.52-2.44%) were detected in all oil samples. The major identified monoterpenes were α-pinene (11.27%), β-pinene (20.01%), 1,8-cineole (10.81%) and linalool (28.61%) for P. crassinervium and, α-phellandrene (22.53%) and ∆-3-carene (10.20%) for P. dilatatum. The major sesquiterpenes were bicyclogermacrene (25.03 and 25.07%) for P. arboreum and P. dilatatum, (E)-nerolidol (11.12%) for P. arboreum, germacrene D (11.81%) for P. tuberculatum and, (E)-caryophylene (10.26 and 37.78%) for P. dilatatum and P. tuberculatum. To the best of our knowledge this is the first report about the chemical composition of the leaf essential oils of P. crassinervium and P. tuberculatum.

“…[9][10][11][12] Biological studies of P. arboreum have shown that their nor-volatile and volatile constituents were active against the fungi Cladosporium sphaerospermum, C. cladosporioides, Candida krusei, C. parapsilosis and Cryptococcus neoformans and protozoan Trypanosoma cruzi. 13,14 Despite the widespread use of P. arboreum in traditional medicine, very few studies of its biological potential have been performed. Therefore, we investigated the potential antifungal and antibacterial activities of the nonvolatile and volatile compounds from P. arboreum tissues.…”

This study evaluated the antifungal and antibacterial activities of the extracts and their fractions, essential oils, and major constituents of Piper arboreum tissues. The chemical compositions of P. arborem tissues and major constituent were identified using GC/MS, 1 H and 13 C NMR. All the botanic material tested proved to be specific bactericidal agents against Staphylococcus aureus, with MBC/MIC = 2, including the amide piperetine, the major compound isolated of P. arboreum for the first time. The essential oil of leaves showed antifungal activity against Microsporum gypseum and Epidermophyton floccosum, with MFC values of 312.5 and 125 µg/mL, respectively.
