ANTIOXIDANT AND WOUND HEALING PROPERTIES OF SOME SELECTED PLANTS FROM KPANDO TRADITIONAL AREA: ISOLATION OF FLAVONOIDS FROM ANOGEISSUS LEIOCARPUS (DC) GUILL AND PERR (COMBRETACEAE)

ABSTRACT Twenty-six wound healing plants have been identified in the Kpando Traditional Area in Ghana. The methanol extracts of six of these plants showed some level of antimicrobial activity against wound causing infectious microorganisms. Similarly, four of these plants exhibited significant wound healing properties. Free radical scavenging activity by 1, 1-diphenyl-2-picryl hydrazyl radical (DPPH) indicated a concentration dependent activity with no significant difference from Ascorbic aci...

EXTRACTION OF ALKALOIDS FROM THE STEM OF THE PLANT CRYPTOLEPIS SANGUINOLENTA (LINDL.) SCHLTR.

ABSTRACT The roots of Cryplo/epis sangllino/Cllla have been investigated for their chemical compounds since 1931. But so far, not much has been reported on the stem although they are used in traditional medicine in Ghana. OJ'plo/cpis sallgllino/enla (Lind.) Schlechter (family Periplocaceae) is a medicinal plant used in some African countries against infectious and parasitic diseases. Phytochcmical $creening of the extracts from the stem (bark and wood) of Oyplo/epis sangliino/Cllla revealed t...

EXTRACTION, ISOLATION AND CHARACTERIZATION OF SOME LIMONOIDS AND SOME CONSTITUENTS OF THE ROOT BARK OF TURRAEA HETEROPHYLLA - SMITH (MELIACEAE)

ABSTRACT The root bark of the plant Turraea heterophylla belonging to the family Meliaceae was investigated for its chemical constituents. Phytochemical screening of both the methanolic and methylene chloride extracts indicated the presence of tannins, saponnins, terpenes, steroids and about eight different limonoids. Exhaustive extraction, chromatography and spectral analyses led to isolation of three compounds. The spectrometric analyses and the resulting data - including IR, NMR(H-H COSY a...

Investigation into Iodine Deficiency of Selected Populations within Cape Coast Metropolis and Agona West Municipality in the Central Region of Ghana –Analysis of Iodised Edible Salts and Ur

ABSTRACT The iodine status of staff and pupils of Hillcrest Schools, undergraduates  of UCC, 2016/2017 academic year and a household in  Agona  Swedru  were determined  using Titration Method, Sandell-Kolthoff  Method and a  Novel Method. Discriminant analysis results showed that the Novel Method correctly classified  77.4%  of  the  original  cases.  The  novel  also  had  a  percentage recovery  of125%  and  a  Horwitz  Ratio  of  0.12.  Based  on  these, ...

Effect of Phosphorus fertilizer on growth and yield of cowpea

                         i.            Abstract Four types of soil are found in Liberia. Latosols of low to medium fertility occur in rolling hill and cover about three-fourths of the total land surface. Shallow, coarse lithosols, in the hilly and rugged terrain, cover about one-eighth of the land. Infertile regosols, or sandy soils, are found along the coastal plains they are deficient in nitrogen and phosphorus, which retard the growth and yield of crops. Therefore,...

Secondary Metabolites from Mimosa Pudica: Isolation, purification and NMR Characterization

Abstract: Aim: isolation, purification and NMR characterization of secondary metabolites in Mimosa pudica. Study design: extraction, isolation and identification of the secondary metabolties from the petroleum ether and  metabolites extracts from Mimosa pudica. Methodology: In the course of our study on Mimosa pudica, a compound was isolated and purified using  different chromatographic techniques and the structure of the compound determined on the basis of their  spectroscopic data (IR, H...

Quantitative Determination of Secondary Metabolites and Antimicrobial Activity of Mimosa Pudica

Abstract: The side effects and the increasing microbial resistance to synthetic drugs in the management and  treatment of infections remain an issue in modern medicine, hence the increasing research in phytomedicine.  Therefore in the present study, the active phytocomponents of Mimosa pudica’s wholesome parts were  revealed using quantitative phytochemical analysis. The antibacterial activity of the Ethanolic extract was  studied using Well diffusion method. The activity was tested aga...

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 ...
