The effect of various drying methods on the nutritional composition of Lycopersicum esculentum and Abelmoschus esculentus L.

Abstract Food drying is one of the methods for preserving perishable foods for long periods of time. The nutritional composition of tomato (Lycopersicum esculentus) and okra (Abelmoschus esculentum) was investigated using the commonly available drying methods (sun, oven, and solar drying). The nutritional compositions of these food crops were determined after they have been dried using various drying methods and milled to pass through mesh size. The moisture content of these food samples wa...

Comparative study on the Effect of boiling on the nutritional composition of garden egg solanum melogena

  Abstract Garden egg is a plant with edible fruit and its potential as a medicinal fruit have also been investigated. Extract has been suggested to have effects that could be therapeutic and nutritional. Analyses were carried out to determine the proximate and phytochemical constituents of both processed and raw indigenous Africa eggplant (Solanum macrocarpon and solanum aethiopicum). Proximate analysis of process and raw solanum macrocarpon (WBA) per (100%) showed: 75.13% moisture, 3.50% ...

Nutritional composition of processed and unprocessed samples of unripe plantain (musa*paradisiaca)

Abstract People usually think food processing bring about reduction in food nutrients as well as the quantity because few quantities must have been lost or wasted during processing, many said food processing affect the taste and color of the food when compared to its whole form. Meanwhile, food processing which also includes its preparation makes food last longer than when in its whole form (increases its shelf life), although its positive effects are numerous but its negative effects canno...

Physico-chemical Parameter Review of Drinking Water Portability at Daranna Community, Bagudo LGA of Kebbi State, Nigeria

Drinking water quality was investigated at Daranna community the mineral rich part of Kaoje town in Kebbi state, to ensure the continuous supply of clean and safe drinking water for the public health protection. In this regard, a physical and chemical analysis of drinking water samples was carried out for samples collected at different locations within the community areas. A number of parameters such as colour, temperature, pH, electric conductivity, dissolved oxygen, total hardness, COD, ...

In-vivo Anti-inflammatory Activity Studies of Some P-nitrophenyl Hydrazones

The goal of this research was the discovery of newer anti-inflammatory drug. Four hydrazones with p-nitrophenyl moiety were synthesized by solvent-free and conventional synthetic methods with good to excellent yields. The synthesized hydrazones were evaluated for their anti-inflammatory activities using carrageenan-induced paw edema in mice. All the compounds indicated significant anti-inflammatory activity, demonstrating slow onset of action and longer duration of action compared to celecoxi...

Phytochemical and Antimicrobial Studies of Xylopia Aethiopica Stembark Extracts

The preliminary screening of phytochemical constituents of extracts of Xylopia aethiopica was evaluated. The n-hexane extract revealedthe presence of terpenoids, alkaloids, and steroids, while the presence of alkaloids, terpenoids, saponins, steroids, and phenolics was indicated in ethyl acetate extract, and the methanol extract contained tannins, flavonoids, phenolics, terpenoids, saponins, alkaloids, steroids. The medicinal property of the extracts was investigated using in-vitro antimicrob...

Structure-based Discovery of Multi-target Directed Anti-infammatoryp-nitrophenyl Hydrazones; Molecular docking, drug-likeness, in-silicopharmacokinetics, and toxicity studies

We designed novel p-nitrophenyl hydrazones as multi-target inhibitors of COX-2, 5-LOX, and H+/K+ ATPase in a bid to overcome side effects associated to NSAIDs and coxibs. Specifically, compounds 1-(4-nitrophenyl)-2-[(3,4,5-trimethoxyphenyl)methylidene] hydrazine (3), 4-hydroxy-2-methyl-6-[(2-(4-nitrophenyl)hydraz-1-ylidene)methyl]thiochroman-1,1-dioxide (6), 4-methoxy-2-methyl-6-[(2-(4-nitrophenyl)hydraz-1-ylidene)methyl]thiochroman-1,1-dioxide (8), 2-methyl-6-[(2-(4-nitrophenyl)hydraz-1-ylid...

SYNTHESIS AND CHARACTERIZATION OF TRANSITION METALCOMPLEX WITH PYRIDL BASED SCHIFF BASE AS LIGANDS

The pyridyl based Schiff base ligands from 2-aminopyridine and benzaldehyde and 2-aminopyridine and 2, 4-dihydroxylbenzaldehyde were synthesized by: 1. For Schiff base from 2-aminopyridine and benzaldehyde; Distillation of Benzaldeyde to ensure maximum purity from possible contaminant like water and ammonia, and refluxed with freshly prepared 2-aminopyridine. The refluxing was done with ethanoic acid catalyst at a time and without catalyst. The process was followed up with Thin Layer Chromato...

Comparison of Different Properties of Paper and Pulp From Various Agrowaste Biomass ( Sugarcane bagasse, coir Fibre and maize stalks)

This study presents the comparison of various properties of paperboard from various Argo wastes. The agro wastes under study in this project include sugarcane bagasse, coir fiber (coconut husk) and maize stalk. The properties differ as a result of the composition and structure of the biomass that is put into consideration that is the amount of cellulose, hemicellulose and lignin available in the agro waste biomass. Paper is basically made from cellulose fibers therefore the project aims to di...

Assessing University Research Governance Practices And Structures In Developing Countries: The Nigerian Universities’ Experience

ABSTRACT While most universities in the developed world, by tradition, have research offices to handle research management, structures for the efficient coordination and strong governance of research are nascent within many Sub-Saharan African universities. In this paper we look at the organizational structures, policies and functions of research offices for supporting faculty research as well as their management operations in 5 selected Nigerian universities. The authors interviewed 20 part...

Interaction of Multiwalled Carbon Nanotube Produces Structural Alteration of DNA

ABSTRACT Multiwalled carbon nanotube (MWCNT) has been found to produce structural changes in Calf Thymus-DNA (CT-DNA). The interaction or binding of the multi-walled carbon nanotubes (MWCNT) was investigated in order to discover if it brings about any significant changes of the DNA double helix using CD spectra of the CT-DNA at two concentration levels of MWCNT representing an increasing MWCNT/DNA molar ratio. In addition, spectrophotometric titrations between MWCNT and CTDNA were carried ou...

RELEASE KINETICS OF CYMBOPOGON CITRATUS ESSENTIAL OIL FROM STARCH BEADS

ABSTRACT The essential oil of Cymbopogon citratus was extracted using a green method (i.e. essential oil still), encapsulated into cassava starch matrix using sodium alginate as a binder. The encapsulated sodium alginate starch beads were characterized using Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectrophotometer (FTIR), release kinetics of the oil was monitored by UV-Visible Spectrophotometry from two (2) aqueous media, buffer of pH 4 and pH 9. The result for ...

CHARACTERISATION OF ESSENTIAL OIL FROM LEAVES OF Euphorbia heterophylla AND ITS INSECT REPELLENT POTENTIAL

This study aimed at characterizing essential  oil  from leaves of  E.heterophylla and its insect repellent potential. Essential oil from fresh leaves of  E.heterophylla was extracted by  hydro distillation method, using a  Clevenger apparatus for 4 hours and the  yield was 0.1816%w/w. Repellence  test was conducted by  using 5 cockroaches in number which were  placed in a modified Y-tube Olfactometer and observations recorded for  each and every  odour introduced after 5 minutes i...

NATURAL WATER HARDNESS, POLLUTION, WATER CYCLE, TREATMENT AND USES

 PREFACE The concept of Natural Water Hardness has been a subject of much discussion since the exception of the natural science unit. It borders on the sources of water hardness, types of hard water and effects of hard water. Pollution on the other hand is an environmental problem which needs to be tackled. This term paper writes more on it. Water cycle, treatment and uses are also discussed in the term paper.    TABLE OF CONTENTS Title Page Dedication Acknowledgment Preface Table of ...
