Ethnobotany of the genus Piper ( Piperaceae ) in Thailand
Thailand is located in the tropical rain forest zone above the equator. This geographically supports very rich biodiversity, including the genus Piper (Piperaceae). 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 کاملA Late Cretaceous Piper (Piperaceae) from Colombia and diversification patterns for the genus.
PREMISE OF THE STUDY Documented fossil floras in the neotropics are sparse, yet their records provide evidence on the spatial and temporal occurrence of taxa, allowing for testing of biogeographical and diversification scenarios on individual lineages. A new fossil Piper from the Late Cretaceous of Colombia is described here, and its importance for assessing diversification patterns in the genu...
متن کاملProteomic 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...
متن کاملGeographic Variation in Host-Specificity and Parasitoid Pressure of an Herbivore (Geometridae) Associated with the Tropical Genus Piper (Piperaceae)
The extraordinary diversity of tropical herbivores may be linked to hostplant specialization driven in part by variation in pressure from natural enemies. We quantified levels of host-specificity and parasitoid attack for the specialist herbivore, Eois (Geometridae). The goals of this research were to examine: 1) whether Eois are specialized on the genus Piper (Piperaceae) and if hostplant spec...
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...
