“…In the case of P. multiplinervium and P. reticulatum, the compositions found in our analysis are roughly in accordance with the ones previously described in samples from Colombia and Brazil, in which several mono-and sesquiterpenes were the major components [22,29]. The larvicidal activity against the dengue vector, A. aegypti (Culicidae), was evaluated for six of the essential oils.…”

The chemical composition of leaf essential oils from 11 species of Piper from Panama was analyzed by a combination GC-FID and GC-MS procedures. Six of them had sesquiterpene hydrocarbons as major constituents, three were characterized by monoterpene hydrocarbons, one by a diterpene, and one by a phenylpropanoid, dillapiole. The main components identified in each species were: cembratrienol (25.4 %) in Piper augustum; β-pinene (26.6 %) in Piper corrugatum; α-pinene (19.4 %) in Piper curtispicum; trans-β-farnesene (63.7 %) in Piper darienense; p-cymene (43.9 %) in Piper grande; dillapiole (57.7 %) in Piper hispidum; linalool (14.5 %), α-phellandrene (13.8 %), and limonene (12.2 %) in Piper jacquemontianum; β-caryophyllene (45.2 %) in Piper longispicum; linalool (16.5 %), α-phellandrene (11.8 %), limonene (11.4 %), and p-cymene (9.0 %) in Piper multiplinervium; β-selinene (19.0 %), β-elemene (16.1 %), and α-selinene (15.5 %) in Piper reticulatum; and germacrene D (19.7 %) in Piper trigonum. The essential oils of P. hispidum and P. longispicum at a concentration of 250 µg/mL showed larvicidal activity against Aedes aegypti, while the oils from P. curtispicum, P. multiplinervium, P. reticulatum, and P. trigonum were inactive (LC100 ≥ 500 µg/mL). The essential oils of P. grande, P. jacquemontianum, and P. multiplinervium showed no significant antifungal activity (MIC > 250 µg/mL) against several yeasts and filamentous fungal strains.

“…Furthermore, the EOs from seven Brazilian Amazonian populations of Pa showed two different chemotypes, one rich in α-pinene (40.9–53.1%)/β-pinene (17.2–22.9%), and one rich in α-eudesmol (33.5%)/ishwarane (19.1%) [ 38 ]. The EO from P. reticulatum studied here contained the phenylpropanoid apiol as the main component (15.0%) while β-elemene (24.6%) and β-caryophyllene (16.7%) were abundant in a Pr oil from the northern region of Brazil [ 39 ].…”

“…The essential oils studied here have shown important activities against phytopathogenic fungi (G2-4). Essential oils from the genus Piper have been reported to have a wide range of biological properties [ 10 , 11 , 14 , 21 , 40 ], including fungicidal effects [ 35 , 38 , 39 ]. Specifically, among the species studied here, the essential oils of P. tuberculatum (rich in α- and β-pinene 17–27%, (E)-β-ocimene 14% and β-caryophyllene 32.1%) [ 41 ], and P. anonifolium (with selin-11-en-4α-ol 20.0%, β-selinene 12.7%, and α-selinene 11.9%) showed strong antifungal activity against Cladosporium cladosporioides and C. sphaerospermum [ 37 ].…”

The chemical composition of essential oils (EOs) from ten Peruvian Piper species (Piper coruscans, Pc; P. tuberculatum, Pt; P. casapiense, Pcs; P. obliquum, Po; P. dumosum, Pd; P. anonifolium, Pa; P. reticulatum, Pr; P. soledadense, Ps; P. sancti-felicis, Psf and P. mituense, Pm) has been studied, along with their antifungal and phytotoxic activities. These EOs contained β-bisabolene/nerolidol (Pc), β-bisabolene/δ-cadinene/caryophyllene (Pt), caryophyllene oxide (Pcs), bicyclogermacrene/10-epi-Elemol (Po), bicyclogermacrene/germacrene-D/apiol (Pd), caryophyllene/germacrene-D (Pa), germacrene-D (Pr), limonene/apiol (Ps), apiol (Psf), and apiol/bicyclogermacrene (Pm) as major components, and some are described here for the first time (Ps, Pcs, Pm). A composition-based dendrogram of these Piper species showed four major groups (G1: Pc and Pt, G2: Pcs, Po, Pd, Pa, and Pr, G3: Ps, and G4: Psf and Pm). The spore germination effects (Aspergillus niger, Botrytis cinerea, and Alternaria alternate) and phytotoxicity (Lolium perenne and Lactuca sativa) of these EOs were studied. Most of these Piper essential oils showed important activity against phytopathogenic fungi (except G1), especially against B. cinerea. Similarly, most of the essential oils were phytotoxic against L. perenne (except G1), with P. sancti-felicis (G4), P. casapiense (G2), and P. reticulatum (G2) being the most effective. Caryophyllene oxide, β-caryophyllene, β-pinene, limonene, α-humulene, and apiol were evaluated against B. cinerea, with the most effective compounds being β-pinene, apiol, and limonene. This work demonstrates the species-dependent potential of essential oils from Peruvian Piper species as fungicidal and herbicidal agents.

“…Além do potencial medicinal, são relativamente abundantes na literatura relatos da produção de óleo essencial nas folhas da espécie. São relatados rendimentos de 0,2 a 0,53%, sendo os compostos majoritários mais comumente descritos: αpineno, β-pineno, trans-nerolidol, óxido de cariofileno, trans-cariofileno, β-cariofileno, γ-elemeno, β-elemeno, β-pireno, α-pireno, limoneno e α-terpineno (Luz et al, 2003;Sacchetti et al, 2005;Tognolini et al, 2006;Perigo et al, 2016).…”

O objetivo do presente trabalho foi avaliar o efeito de diferentes concentrações do regulador vegetal ácido indolbutírico (AIB) no enraizamento e brotações de estacas caulinares de Piper crassinervium. Estacas caulinares de 12±1 cm, contendo uma folha reduzida a um terço de seu tamanho, tiveram suas bases imersas por 15 segundos em soluções hidroalcoólicas (50%) com concentrações de zero, 500, 1000, 2000 e 4000 mg L-1 de AIB. Após 45 dias da instalação do experimento, foram avaliadas as porcentagens de sobrevivência, enraizamento, estacas que mantiveram as folhas na região apical (retenção de folhas) e estacas com emissão de novas brotações, número, comprimento médio e massa seca de raízes e massa seca de brotações. Foram observadas altas porcentagens de enraizamento (média 75,83%) e sobrevivência (média de 79,58%), ambas não influenciadas pelas concentrações de AIB. As variáveis de porcentagens de estacas com novas brotações, massa seca de raiz e de brotações foram as únicas que apresentaram resposta significativa à aplicação do regulador, demonstrando inibição à medida que se aumentaram as concentrações. É viável a propagação de P. crassinervium via estaquia caulinar. A espécie apresenta altos índices de enraizamento e sobrevivência, não sendo necessária a aplicação do regulador vegetal AIB.
