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...

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...

Eois is one of the best-investigated genera of tropical moths. Its close association with Piper plants has inspired numerous studies on life histories, phylogeny and evolutionary biology. This study provides an updated view on phylogeny, host plant use and temporal patterns of speciation in Eois. Using sequence data (2776 bp) from one mitochondrial (COI) and one nuclear gene (Ef1-alpha) for 221...

Fish and other organisms with aquacultural potential live in water, thus, it is no surprise that professional fish culturists state that "Water quality determines to a great extent the success or failure of a fish cultural operation" (Piper et al. 1982). Because water is an essential requirement for fish farming, any properly prepared business plan for aquaculture must describe the quality and ...

While the association of eczema with asthma is well recognized, little research has focused on the potential role of inhalable exposures and eczema. While indoor air quality is important in the development of respiratory disease as children in the U.S. spend the majority of their time indoors, relatively little research has focused on correlated non-respiratory conditions. This study examined t...
