PHYTOCHEMICAL ANALYSIS AND ISOLATION OF COMPONENTS OF STEM-BARK OF CHRYSOPHYLLUM ALBIDUM (G.Don)

Chrysophyllum albidum (Sapotaceae) is known to possess bioactive compounds belonging to important phytochemical groups. This work aims at exploring the bioactive constituents of the stem-bark of Chrysophyllum albidum, and further investigating their phytochemical compositions. Stem bark of Chrysophyllum albidum was collected, dried, powdered and extracted with hexane for 13 hours using soxhlet extraction. This was concentrated using a rotary evaporator. Phytochemical screenings of the ext...

STUDIES ON THE ANTIBACTERIAL ACTIVITY OF CASTOR OIL SEED ON SOME SELECTED BACTERIA

ABSTRACT  The castor plant is a robust perennial shrub of Euphorbiacaea family.  The seeds are documented to have an antibacterial profile against some bacterial organisms  such as  Escherichia  coli,  Staphylococcus  aureus,  Pseudomonas aeruginosa,    Klebsiella  pneumoniae,  Proteus  vulgaris,  and  Streptococcus pyogenes.  This  study  was  carried  out  to  ascertain  antimicrobial  properties inherent  in  the  extracts  (aqueous,  methanolic  and  n-hexa...

INVESTMENT OF PENSION FUNDS IN NIGERIAN BOND MARKET

ABSTRACT Since the Defined Contributory scheme was introduced to replace the Define Benefit scheme in Nigeria, the pension assets in Nigeria has increased annually. The resultant effect of the increase of pension funds implies more responsibility for the Pension fund administrators to shoulder.

The Nigerian bond market is an avenue for the investment of pensio...

Nutritional and Biochemical Contents of Pepper (Capsicum spp)

         ABSTRACT Pepper (Capsicum spp) belongs to the family Solanaceae. It is an important vegetable crop in Nigeria as it is one of the most varied and widely used foods in Nigeria as virtually every Nigerian home consumes it on a daily basis. The genus Capsicum represents a diverse plant group and includes twenty-seven species; five domesticated and twenty-two undomesticated (Bosland, 1993). The domesticated species are Capsicum annuum, Capsicum baccatum, Capsicum chinense, Capsicum ...

Antimicrobial Effect of Natural Honey and Mango Leave on Pathogenic Bacteria

ABSTRACT  Honey has since been found to possess antibacterial property and is therefore employed for wound and gastro-intestinal disease therapy. This study evaluates the antibacterial spectrum and efficacy of honey and compared with tetracycline.  Different concentrations (50, 75 and 100.0 %) of honey were studied in-vitro using Staphylococcus aureus, Klebsiella spp, Escherichia coli and Citrobacter spp. The data obtained showed the inhibitory action of honey with clear zones of inhibition...

Relating Geology and Geological Structures with Regional Episodes: Implication for Groundwater Exploration and Development around Kwal-Kanke Area, Jos Plateau

Abstract The  study  addressed  the  Geology  and  geological structures around  Kwal-Kanke  area  around  the  Jos  plateau. Three (3) rock types namely; Quaternary dolerite/basic rocks, aplo-pegmatitic  granite  gneiss  and  migmatite-gneiss  were delineated. The  quaternary  dolerites  and  the  aplo-pegmatitic granite  are  emplaced  in  form  of  dykes  with  lateral  extent greater than 3km trending NW-SE and conforms to the trend of the fractures around J...

EFFECTOF METHANOL EXTRACT OF cirtullus lanatus SEEDSON HEMATOLOGICAL PARAMETERS IN MODULATION OF DIHYDROTESTOSTERONE ESTRADIOL VELERATE INDUCED BENIGN PROSTATIC HYPERPLASIA IN MALE WISTAR RA

Citrullus lanatus is medicinal plants believed to have many agents acting in different ways for the health benefits of human. This study investigated the acute phytochemical contents and effect of the methanol extract on weight changes, relative organ weight, hematological parameters and biomarkers of prostate dysfunction. The result indicated the presence of alkaloids, terpenes, flavonoids, Reducing sugar, tannins and phenols. Acute toxicity studies showed that the extract was safe at 5000mg...

Jatropha Tanjorensis Leaf Extract as an Environmentally Friendly Mild Steel Corrosion Inhibitor in Acidic Medium

Abstract : The inhibition of the corrosion of mild steel in 1 M H2SO4 solution by Jatropha tanjorensis leaf extract (JTLE) has been studied using weight loss and hydrogen evolution techniques. The results obtained reveal that JTLE effectively inhibited the corrosion of mild steel in H2SO4 solution. The highest inhibition efficiency of 89.73% occurred at 5.0 g/L JTLE concentration at 333K by weight loss measurements. Inhibition efficiency was found to increase with increase in JTLE concent...

Arithmetic of Analysis (Supremum and Infimum)

I can still remember my expression and feeling when we were asked to show that sup(A + B) = sup(A) + sup(B). It was an herculean task because the concept was too difficult to grasp with the use of approximation property until I discovered an easy route. In a bid to restrict my papers to just few pages, I will focus more on examples than theorems.

A Report on Using Geographic Information System (GIS) to Select Solid Waste Disposal Site: A Case Study in Techiman Municipality, Brong Ahafo Region of Ghana

ABSTRACT Solid waste management over the years has been a serious problem on the nation  Ghana.
