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...

Abstract The chief source of the oilfield scale is mixing incompatible waters. This study demonstrated that reservoir Mishrif formation (Halfaya oilfield) with six types injection water sources, including Tigris River water, producing formation, Gulf seawater, Marshes Middle Kirkuk and Main Outfall Drain (AL-Masab AL-Aam Channel), leads to salt crusts cause reduction rock permeability. Accordin...

Human activities and natural factors determine the hydrogeochemical characteristics of karst groundwaters their use as drinking water. This study assesses 14 water sources in Apuseni Mountains (NW Romania) potential sources. As shown by Durov Piper diagrams, chemical composition waters is typical it dominated HCO3− Ca2+, having a circumneutral to alkaline pH total dissolved solids ranging betwe...

Abstract Wetlands deliver many ecosystem services but are under continuous threat due to various anthropogenic activities. The present study has been carried out examine the suitability of Kusheshwar-Asthan wetland's water for agriculture. A total 57 samples were analyzed quality parameters like electrical conductivity, pH, temperature, dissolved oxygen (DO), major cations (Ca2+, Mg2+, Na+, K+)...

Abstract The People's Victory Canal Irrigation Area is a large gravity irrigation area in the middle and lower reaches of Yellow River. Groundwater hydrochemistry controlled by geochemical weathering, precipitation, from River diversion, artificial exploitation. Piper diagram, hierarchical cluster analysis, Gibbs ion proportion coefficient were applied to improve our understanding hydrogeochemi...

objective:the present study was designed to evaluate the antioxidant, analgesic, and anti-inflammatory activities ofthe methanolic extract of piper betle leaves (mpbl). materials and methods: mpbl was evaluated for anti-inflammatory activity using carrageenan-induced hind paw edema model. analgesic activity of mpbl was evaluated by hot plate, writhing, and formalin tests. total phenolic and fla...

background: piper guineense (pg) and sesamum indicum (si) have been shown to be rich sources of antioxidants and other health benefits; hence, we evaluated the impact of its consumption in hypercholesterolemic model on lipid metabolism. methods: forty-eight animals were divided into eight groups of six rats each. rats were given cholesterol (40 mg/0.3ml), pg and si extract (100 and 200 mg/kg), ...

Fusarium solani f. sp. piperis (teleomorph: Nectria haematococca f. sp. piperis), causal agent of root rot and stem blight on black pepper (Piper nigrum), produces secondary metabolites with toxigenic properties, capable of inducing vein discoloration in detached leaves and wilting in transpiring microcuttings. Production of F. solani f. sp. piperis (Fsp) toxic metabolites reached a peak after ...

BACKGROUND Wound healing has being extensively investigated over the world. Healing impairment is caused by many reasons including increasing of free-radicals-mediated damage, delaying in granulation tissue formation, reducing in angiogenesis and decreasing in collagen reorganization. These facts consequently lead to chronic wound healing. Piper betle Linn (Betle) leaves have been folklore used...

INTRODUCTION Previous studies have shown that Piper betle L. leaves extract inhibits the adherence of Streptococcus mutans to glass surface, suggesting its potential role in controlling dental plaque development. OBJECTIVES In this study, the effect of the Piper betle L. extract towards S. mutans (with/without sucrose) using scanning electron microscopy (SEM) and on partially purified cell-as...
