Piper nigrum leaves were collected from five locations from Kerala within a radius of 150 km, altitudinal variance of 1000m and annual rainfall variance of 1400mm. The extracted Piper nigrum leaf oil was profiled using a GC-MS, Beta Caryophyllene was the only constituent that was present in all the five locations, of which the highest concentration was noted in the high altitude region of Idukk...

A simple, rapid and precise spectrophotometric method has been developed for the estimation of piperine in Ayurvedic formulation Chitrakadi Vati. Three marketed preparations of Chitrakadi Vati containing black pepper (Piper nigrum) and pippali (Piper longum) from different manufacturer (CV-1, CV-2 and CV-3) were taken in this study to estimate the % w/w of piperine. The % w/w content of piperin...

He who pays the piper calls the tune, but he can only succesfully call for a tune that he will recognize upon hearing. Previous models, of two candidates impressing a voter and of firm managers impressing stock speculators, found experts ignoring costly superior information in favor of client preconceptions. Similar result hold when we greatly generalize the agents, choices, information structu...

Piper solmsianum C. DC. var. solmsianum (Piperaceae) is a shrub commonly found in areas with wet tropical soils. Other Piper species have been used in folk medicine as antitumoral and antiseptic agents. We studied the crude methanolic extract, some organic fractions and compounds isolated from this plant for possible antimicrobial activity against Gram-positive and Gram-negative bacteria. The b...

The increasing population, erratic distribution of rainfall, and their rising demand for water in domestic irrigation are fulfilled by groundwater resources. Due to overexploitation, there is the deterioration quality, hence evaluate a study was undertaken understand suitability drinking as well purposes. For this study, five villages, namely Kumulur, Tachankurunchi, Pudurutamanur, Pandaravadai...

The exploitation of groundwater in arid and semi-arid areas, especially basins where is intensively exploited, likely to have adverse effects on the originally fragile ecological environment, which also greatly alter hydrogeochemical evolution process. Over-abstraction Haolebaoji watershed Ordos Basin located regions has led a series changes system, attracted considerable attention from environ...
