Proteomic profile of Piper tuberculatum (Piperaceae).
Piper tuberculatum (Piperaceae) is a species that accumulates especially amides as secondary metabolites and several biological activities was previously reported. In this article, we report a proteomic study of P. tuberculatum. Bidimensional electrophoresis (2D SDS-PAGE) and mass spectrometry (ESI-Q-TOF) were used in this study. Over a hundred spots and various peptides were identified in this...

Thirtyeight species of Piper, from out of over 1,000 species in the world, have been discovered recently (1998-2006) by the authors. Plant morphology and plant use information were recorded via observation, market surveys, and inter...
متن کاملChemical constituents of Piper betle Linn. (Piperaceae) roots.
Column chromatography of the alcoholic extract of Piper betle roots furnished aristololactam A-II and a new phenyl propene, characterized as 4-allyl resorcinol, while the petroleum-ether extract yielded a diketosteroid, viz. stigmast-4-en-3,6-dione. All these compounds were characterized by spectroscopic means. Isolation of these compounds from this source is being reported here for the first t...
متن کاملAntifungal activity of Piper diospyrifolium Kunth (Piperaceae) essential oil
In vitro activity of the essential oil from Piper diospyrifolium leaves was tested using disk diffusion techniques. The antifungal assay showed significant potencial antifungal activity: the oil was effective against several clinical fungal strains. The majority compounds in the essential oil were identified as sesquiterpenoids by GC-MS and GC-FID techniques.
متن کاملIsolation of Monoterpene Dihydrochalcones from Piper montealegreanum Yuncker (Piperaceae).
Four new compounds were isolated from the branches of Piper montealegreanum Yuncker, a shrub found in the Amazon rainforest, including two new dihydrochalcones named claricine (1) and maisine (2), a cinnamic acid derivative 3 and a phenylalkanoid 4, along with a porphyrin identified as the known compound phaeophytin a (5). The structures were established using spectroscopic experiments, includi...
