Extraction and Isolation of Palm Husk Ash for Determinations of Potassium and Sodium Ratio

2022-03-10T17:10:08+00:00

The purpose of the study was to extract crystal of alkalis from palm husk; quantify the alkalis contents of the ashes; and to determine potassium-sodium ratio using flame photometer.

Results from the preliminary treatment showed that the Moisture content (MC) was 6.41%, Ash Content AC 58.19%, Loss in Weight (LW) 41.81%, Alkali Content (AKC) 5.56%, %Residue was 93.21%, and efficiency of crystallization was 81.94%. The analysis of the alkali ion conc. of CO₃^2- and HCO₃^- potassium to sodium ratio was 13:1 and 1:234 for flame photometer result.

Phytochemical Screening and Antioxidant Activities of Purple and White Skinned Sweet Potato (Ipomea Batatas)

2022-03-26T15:18:44+00:00

The purpose of this study was to isolate the phytoconstituents of purple and white skinned sweet potato (Ipomea Batatas).The extracts from the four different samples of Ipomea batatas exhibit saponins, steroids, flavonoids. Alkaloids and cardiac glycosides. The extracts from the sweet potato samples in tannic acid equivalent showed higher activities at 30.55356 mg/g for white cooked sample, 30.38581 mg/g for purple cooked, 19.6022 mg/g for purple raw and 12.14953 mg/g for white raw. It could be concluded that the food sample contain an array of essential nutrients as well as phytochemicals which make them possess antioxidant function as well as other bioactivity.

Characterization of Tm (III) -sulphonananilide systems in terms of thermodynamic and electronic-spectral parameters

2022-04-05T06:56:08+00:00

The complexes of d-block transition metals with various ligands have been studied extensively. However, in case of f-block lanthanide metal complexes, a limited study has so far been carried out. Systematic study of lanthanide complexes began only after the publication of Judd-Ofelt theory in 1962. Several lanthanide complexes were prepared with the ligands possessing “O” and “N” as donar atoms and examined for various electronic-spectral parameters resulting from f-f transitions.

In the present work, electronic-spectral characterization of various Tm(III) systems in DMF medium involving sulphonanilide ligands having “O”, “N” and “S” donar atoms will be examined on the basis of theories given by Lande, Carnall & Judd-Ofelt

The complexing ability has been reported poor in case of lanthanide complexes and also the stability of lanthanide complexes is found similar to [Ag(NH₃)₂]⁺ type of complex, which makes the isolation of these complexes in solid state difficult. Owing to the poor thermodynamic stability of lanthanide complexes, a modified doped model technique will be taken as system in the present electronic-spectral study.

Synthesis and Characterization of Some 1,3,4-oxadiazole derivatives

2022-04-09T06:00:25+00:00

Reactions of N-isocyaniminotriphenylphosphorane with cyclopentanone have been studied in the presence of aromatic carboxylic acids and primary amines. The reactions were proceeded smoothly at room temperature under neutral conditions in order to afford sterically congested 1,3,4-oxadiazole derivatives by an intramolecular Aza-Wittig cyclization in dichloro methanein excellent yields. The structures of the products were deduced from their IR, Mass, ¹H NMR, and ¹³C NMR spectra. The method offers a mild, simple, and efficient route for the preparation of fully substituted1,3,4-oxadiazoles from cyclopentanone, primaryamines, N- isocyaniminotriphenylphosphorane and aromatic carboxylic acids. Easy work-up, high yields and fairly mild reaction conditions make it a useful procedure in comparison to the modern synthetic methodologies.

Phytochemical and Antimicrobial Activities of the Leaves and Roots Extracts of Lemon Grass (Cymbopogon Citrates) from Basiri, Ado-Ekiti, Ekiti State, Nigeria

2022-04-16T09:10:00+00:00

The research study aimed to extract Cymbopogon citratus leaf and root using various solvents with view to determine the phytochemical analysis and antimicrobial effect of the plant extracts on selected microorganisms. All the extract was subjected to phytochemical and antimicrobial activities for the presence and absence of various primary and secondary metabolites. Phytochemicals such as alkaloids, tannins, phenol, reducing sugar and saponin were present in both leaf and root extracts. And this revealed that the presence of the phytochemical which could be used for medical regimens. Antimicrobial screening showed that the plant is biologically active against Staphylococcus aureus and Escherichia coli.
