In vitro ANTIOXIDANT ACTIVITY AND PHYTOCHEMICAL PROPERTIES OF METHANOL, ETHANOL AND HEXANE EXTRACTS OF Azadirachta indica LEAVES.

ABSTRACT Azadirachta indica, commonly known as Neem, has attracted worldwide prominence in recent years as a cynosure of modern medicine owing to its wide range of medicinal properties. This study was carried out to investigate the phytochemical properties and antioxidant activity of the multi-solvent (methanol, ethanol and hexane) extracts of the leaves of Azadirachta indica of Meliaceae family. The extracts were investigated for phytochemical constituents such as tannins, saponins, alkaloid...

The software system was developed within the Microsoft Visual Studio environment. ASP.NET is used to create the pages. The database is generated and managed using MySQL. The codes were scripted usin...

Phytochemical Screening and Proximate Analysis of Aloe Vera Growing on Highland and Lowland Areas of Sokoto Metropolis

ABSTRACT Phytochemical and Proximate analyses of two samples of Aloe vera from variable habitats (highland and lowland) of Sokoto metropolis were accessed. Phytochemical and proximate compositions of highland sample were 8.16mg/100g of Saponin, 3.40mg/100g of Glycoside, 1.80mg/100g of Alkaloid and 2.50mg/100g of Anthraquinone. Proximate constituents’ analysis revealed 6% of Moisture, 10.5% of Ash, 2.5% of Crude lipid, 8.13% of Crude protein, 1% of Crude fibre and 70.57% of Carbohydrate resp...

Neuroprotective Effect of Croton Zambesicus Phenolic Extract on Synaptosomes of Rats Exposed to Environmental Toxicant

ABSTRACT Exposure to environmental toxicant was known to cause neuronal disorders in humans. Hence, the present study evaluates the toxic effect of leachate (an environmental toxicant) in the synaptosomes of female rats and the reversal effect of phenolic-rich fraction from Croton zambesicus. Fifty animals were divided into five groups. Group I (Control) received 0.5ml of distilled water only, Group II (non-withdrawal) received 0.5ml of leachate for 14 weeks, Group III (withdrawal) received 0...

EFFECT OF TYPE OF CUTTINGS ON ROOTING OF ANACARDIUM

Vegetative propagation method through induction of adventitious rooting in both softwood and semi- hardwoodhypocotyl plus stem (HpS) and juvenile stem (JS) was reported in Anacardium occidentale, an average size tropical evergreen tree belonging to the Anacardiaceae family. The induction of adventitious roots is an essential process in vegetative propagation. Adventitious rooting in above cuttings was induced by exogenous application of root promoting substances (RPS) viz. Indole-3-butyri...

Geology and Water Quality Assessment of Okpoma Salt Lake Areas in Yala Local Government Area of Cross-River State, Nigeria

ABSTRACT Geology and Water Quality Assessment of the Salt Lake areas of Okpoma and its environs in Yala Local Government Area of Cross River State has been carried out. The study area lies between longitude 08o 361 E to 08o 411 E of the equator and latitude 06o 321 N to 06o 371 N of the meridian respectively. They belong to the Eze-Aku Group of the Late Cenomanian- Turonian age Southeastern Nigeria. Lithologically the area is underlain by shales and intercalation of sandstone. Igneous intrusi...

Petrophysical characterization of Reservoir Sands of Two Wells in the Offshore Depobelt of the Niger Delta Basin

Petrophysical well logs were integrated in an analysis for the reservoir characterization of C and D wells located in the Offshore Depobelt of the Niger Delta Basin, Nigeria. The study essentially determined reservoir properties such as Lithology, shale volume, Porosity, hydrocarbon saturation and Net-Gross from Well logs with a  view to determining the Reservoir quality. Two lithologies were identified using Gamma ray and Resistivity logs which were sand and shale but minor presence of carb...
