Bio-prospective Screening of Antibacterial and Phytochemical Activity of Caesalpinia pulcherrima.Linn (Pride of Barbados) on Selected Clinical Isolates

This work was carried out to evaluate the antibacterial and Phytochemical activities of Caesalpiniapulcherrima  leaf and stem bark on some clinical isolates. The plant parts were collected from St. Benedict Catholic Church premises, Owena Barracks, Akure, Ondo State. Crude ethyl acetate extracts of Caesalpinia pulcherrima leaves and stem bark was assayed for its antibacterial activity against Staphylococcus aureus, Klebsiella pneumonia, Pseudomonas aeruginosa, Bacillus subtilis, Escheric...

Prospects of Essential Oils in Drug Discovery

Abstract Essential oils (EO), according to the International Standard Organization (ISO)  defines essential oil as the product obtained from parts of plants by distillation with water steam and the product obtained by expression from pericarp of medicinal plant. The rapid growth and increase of the knowledge of identification, extraction, purification and characterization of essential oils in most local plant species is fast becoming an important aspect of the drug production process. ...

Evaluation of Antimicrobial Activity, Synergistic Efficacy, Qualitative and Quantitative Phytochemical Determination of Alstonia Boonei Leaf and Stem Bark on Selected Clinical Isolates

Abstract This study evaluated the antimicrobial activity, of Alstonia boonei leaf, stem bark and the synergistic efficacy of A. boonei leaf plus stem bark on seven bacteria (Gram positive and Gram negative bacteria) which are strains of Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Proteus viridans, Salmonella typhi and Klebsiella pneumoniae, and three fungal isolates which are Candida albicans, Aspergillus flavus and Trichophyton rubrum. This study also ...

Evaluation of Antimicrobial Activity, Phytochemical Screening and Gas Chromatography-Mass/ Spectrophotometric Profile of Essential Oil from Persea americana & Citrus sinensis

Abstract This study aims to determine the phytochemical characteristics, structural determination of bioactive component from the leaf extract  using GCMs and experimentally investigation of the antibacterial activity of essential oil from Persea americana and Citrus sinensis leaf against seven bacteria (Gram-positive and Gram-negative) which are Staphylococcus aureus , Bacillus subtilis, Salmonella typhi, Klebsiella pneumonia, Escherichia coli, Proteus mirabilis and Pseudomonasaeruginosa kn...

Efficacy of Essential Oils from Persea Americana stem bark and Seed extracts

 The aim of the study is to evaluate the Antibacterial, Phytochemical analysis of Essential Oil, From the Stem Bark and seed extracts of Persea americana (Avocado). This was carried out by the crude extraction of the seeds and stem bark extracts with n-hexane. The extracts were used to determine the presence of Phytochemicals. Stock cultures of test organism such as Staphylococcus aereus, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Bacillus cereus, Proteus mirabilis were...

Assessment of Antimicrobial, Phytochemical Screening and Gas Chromatography-Mass Spectrophotometric Profile of Crude Chrysophyllum Albidum Essential Oil

Abstract The main purpose of this work is to investigate and compare the antimicrobial properties of Chrysophyllum albidum seed and stem bark essential oils, against some selected pathogenic isolates, to compare the phytochemical composition of the oil of Chrysophyllum albidum seeds and stem bark, to analyze the chemical compounds responsible for activities of the essential oil using Gas Chromatography – Mass Spectrometer (GC-MS) method in order to provide scientific validation for their us...

THE EFFECT OF DENSITY VARIATION ON THE EARTH’S STABILITY OVER SOUTH-WESTERN NIGERIA

This research work is meant to determine the Earth’s stability from gravity anomalies and to provide diverse explanations for a wide range of physical observations and also highlight the factors affecting the stability of the Earth. Information from geodesy (shape of the Earth) and the gravitational field of the Earth studies have been fitted together to produce the complex factors affecting the stability of the Earth. This is obtained by developing a mathematical model of the geoid height ...

DETERMINATION OF Escherichia coli AND SOME PHYSICOCHEMICAL PARAMETERS OF SELECTED PIPE BORNE AND SACHETBOTTLED WATER IN ACCRA-

Water treatment describes those processes used to make water more acceptable for a desired enduse. These can include use as drinking water, industrial processes, medical and many other uses. In Ghana, water is the most common and cheapest drink one can afford. For this reason, drinking water is supposed to be clean and safe enough for human consumption. The goal of all water treatment process is to remove existing contaminants in the water, or reduce the concentration of such contaminants so ...

STATISTICAL ANALYSIS OF FACTORS AFFECTING STUDENTS’ ACADEMIC PERFORMANCE IN TERTIARY INSTITUTIONS

School, colleges and universities have no worth without student. Students are most essential asset for any educational institute. The social and economic development of the country is directly linked with student academic performance. The determinants of students' performance have been the subject of ongoing debate among educators, academics, and policy makers. There have been many studies that sought to examine this issue and the findings of these studies point out to hard work and disciplin...

FIELD REPORT ON THE GEOLOGICAL MAPPING OF IGARRA AREA

Basically, geological mapping involves the study of rocks; in situ, that is, in their natural environment and the representation of such rocks on a geological map. Furthermore, rocks of the Igarra area constitute part of the Basement Complex of southwestern Nigeria. On the basis of field relationships and petrological studies, these rocks can be grouped into gneissic rocks, meta-sedimentary assemblages, intrusive igneous rock bodies and sedimentary rocks (formations).             T...

GRAVITY METHOD IN GEOPHYSICAL PROSPECTING

Lateral density changes in the subsurface cause a change in the force of gravity at the surface. The intensity of the force of gravity due to a buried mass difference (concentration or void) is superimposed on the larger force of gravity due to the total mass of the earth. Thus, two components of gravity forces are measured at the Earth's surface: first, a general and relatively uniform component due to the total earth, and second, a component of much smaller size that varies due to lateral d...

Investigation of thermophysical properties of alates (swarmers) termite wing as potential raw material for insulation

Thermo physical properties of Alates (Swarmers) termite wing has been investigated. The result of our investigation shows the values of thermo physical parameters of the sample materials as 0.0403Wm-1K-1 being the mean thermal conductivity value, bulk density of 188. 8kgm-3 and thermal diffusively value being 8.2485 x 10-8m2s-1. The values are within the values for commonly used insulating materials. Comparing the rate of cooling as well as heat absorption into the material as lagging materia...
