Secondary Metabolites From Peperomia Sui

Abstract

One chromone, peperosuione (1), together with eighteen known compounds were identified from the whole plant of Peperomia sui (Piperaceae). Peperovulcanone A (2) isolated firstly from the P. vulcanica also obtained from this study, its structure was revised on the basis of spectroscopic evidences. All of the isolates constituents were determined by means of spectral analyses.

Bioassay-guided discovery of antibacterial agents: in vitro screening of Peperomia vulcanica, Peperomia fernandopoioana and Scleria striatinux

“…The Peperomias constitute a large genus of herbs widely distributed in tropical and sub-tropical regions [ 21 ]. The two species used in this study are found around Mount Cameroon in the South West and in parts of the North West of Cameroon [ 22 ].…”

“…Previous studies have shown that most of the common phytochemical constituents of Peperomia species are phenylpropanoid, benzopyran, chromone, prenylated quinone, secolignan, and acylcyclohexane-1, 3-dione [ 21 , 22 ]. Some of these compounds in the crude extracts and fractions of P. vulcanica and P. fernandopoioana may be responsible for the antibacterial activities observed.…”

­Chemical profiling and biological activity of Peperomia blanda (Jacq.) Kunth

“…Moreover, previous studies have reported Peperomia species to be rich in secondary metabolites. For example, twenty seven compounds were isolated from P. vulcanica and P. fernandopoioana ( Mbah et al, 2012 ), nineteen compounds from P. sui ( Cheng & Chen, 2008 ) and three novel secolignans from P. blanda (cultivated in Brazil) ( Felippe et al, 2011 ). In addition, sterols, two chromones and two C-glycosyl flavones were previously isolated from P. blanda ( Velozo et al, 2009 ) and showed modest antioxidant activity.…”

Existem cerca de 100 trabalhos referentes a estudos com a planta que incluem trabalhos com extratos brutos, óleos essenciais, estudos fitoquímicos e farmacológicos.…”
