Effect of alkaline pretreatment on protein fraction of high tannin sorghum cultivar

One sorghum cultivar ( Karamaka), that is high in tannin content was obtained from Kadogly Research Station .It was used to study the effect of soaking in alkali , cooking and fermentation on proximate composition, protein fraction and tannin content. Results of analysis showed that, the cultivar contained 6.01% moisture , 3.47% fat, 1.55% ash, 2.36% crude fiber, 10.40% crude protein,...

Electrical Inactivation of Bacteria in Beverages

Biophysical method was used for bacterial inactivation in juices and water ( raw water , treated water and sea water)in which a unit composed of a container and two electrodes join together in series with a digital multimeter the distance between the two electrodes determines the value of the current . The result obtained using 0.1 to 0.6 A for 1 and 2 min as residence time and...

Kinetics and Mechanisms of Peroxodisulphate Oxidation of Certain Amino Acids in Acidic Aqueous Solution

Kinetics and mechanism of oxidation of eighteen ^5;-amino acids by peroxodisulphate ion have been studied in an aqueous acidic medium (sulphuric acid) at the temperature range 60-800 C. The rate shows first order dependence on peroxodisulphate concentration, and zero order dependence on amino acid concentration. The rate law observed is: –d[S2O82-]/dt = kobs [S2O82-][Amino acid]0. An...

Synthesis, Characterization, and Coupling of Some Carbonyl Compounds

The susceptibility of the hydrogen atom of the formyl group (-CHO), in aldehydes lacking ^5;-hydrogen atom, to undergo chemical transformation(s) has been investigated. Strong bases, such as alkali metals, alkali metal hydroxides, and alkoxides in the corresponding alcohols, replace the hydrogen atom in the formyl group in the following manner: The products so obtained have been isolated and...

Evaluation of Antitumor Activity of Some Sudanese Medicinal Plants\\\\\\\' Extracts and some of theirSynthetic Analogues

Five Sudanese medical plants’ have been investigated for their medicinal value. Extracts of the whole plants as well as extracts of different parts of the same species were tested for their antitumor activity employing brine shrimp test (BST). All were found to be active; with LC50 in the order namely Acnthospermum hispidum LC50 126 ppm., Whole plant > 1000 ppm., Azadrachta indica (seeds 45...

Determination of Some Trace Elements in Serum of Hyperthyroidism and Hypothyroidism Patients

The objectives of this study are to determine the concentration of the mineral nutrient elements in human serum, and to find a relationship between the concentration of metal ions and hormonal disorder in patients with hyperthyroidism and hypothyroidism. To achieve these objectives the serum samples were collected from patients of different localities in Sudan. Thyroid hormones were...

Application of the Coordination State Theory to Associated Solutions Limited Case: Estimation of Vapor Composition and Vapor Pressure of Alcohols and Hydrocarbons Binary Systems

The objectives of this study were to apply the coordination state theory to associated systems, specifically to estimate vapor pressure and vapor composition of alcohols and hydrocarbons binary systems. To achieve these objectives, a computer program in Q. basic language was used to compute vapor composition and vapor pressure of many alcohols and hydrocarbons binary systems. The systems...

Analytical Applications Of Propanic Hydroxamic Acid And Some Of Its Derivatives For Determination Of Some Metal Ions

Hydroxamic acids of propanic acid and those of three of its derivatives i.e. alanine, pyurvic and lactic acid were prepared via preparation of methylester of each acid and coupling it with hydroxylamine in alkaline medium at O°C. The preparation of these acids was verified by determination of nitrogen content and the characteristic colour test with acidic solution of V(V) in chloroform and...

Chemical Constituents And Molluscicidal Activity Of Azadirachta Indica A.Juss (Neem) Leaf Extract

This research aims at assessing the molluscicidal effect of Neem (Azadirachta indica) leaf extracts on fresh water snails, the intermediate host of schistosoma species. The fine powder of the Neem leaf was extracted using water, ethanol, methanol, petroleum ether, chloroform, and butanol and the molluscicidal effect on Biomphalaria pfeifferi and Bulinus truncatus snails of each extract was...
