Identification of Polyphenols and Anti-Oxidant Capacity of Piper aduncum L
Ethanol extracts of Piper aduncum L. leaves from five sub-regions in the tropical Peruvian rainforest were assessed for polyphenol content utilizing liquid chromatography coupled with mass spectrometry with electrospray ionization (LC-MS-ESI). The anti-oxidant capacity was estimated using a DPPH radical scavenging assay. Additionally, the reducing power (capacity to reduce Fe 3+ to Fe 2+ ), the...
متن کاملVolatile chemical constituents of Piper aduncum L and Piper gibbilimbum C. DC (Piperaceae) from Papua New Guinea.

متن کاملEvaluation of Piper aduncum Linn. Essential Oil (Fam:Piperaceae) against Periplaneta americana (L.)
BACKGROUND The efficacy of Piper aduncum essential oil was evaluated against Periplaneta americana adults and nymphs in the laboratory. METHODS The plant essential oil at varying concentrations ranging between 10,000 to 80,000 ppm were placed inside glass beakers, rolled horizontally to ensure the essential oil covers all sides of the beakers and exposed to adults and nymphs of P. americana. ...
متن کاملPiper aduncum Fallows in the Lowlands of Papua New Guinea
rimary forest covers about 75% of Papua New Guinea. Every year about 200,000 ha are cleared for commercial operations, including logging, plantations, and subsistence agriculture. The latter mainly takes the form of shifting cultivation. In many parts of the humid lowlands, secondary fallow vegetation is dominated by the shrub Piper aduncum L (see color plate 20). It is not known exactly when a...
