The introductory chapter of this thesis outlines multicomponent reactions and describes in detail the chemistry of the Mannich reaction. The final section of the introduction deals with chemical informatics Ten compounds of β-aminoacetophenone derivatives were synthesized by the condensation of ketone (acetophenone or p-bromoacetophenone) with different aromatic amines and benzaldehyde; general preparative method, ACD/lab programmer method and Swiss target prediction method for synthe...
Vegetable tannage is an eco-friendly method compared with environmental polluting chromium based method of tanning that is commonly used in commercial tanning and which prevents the collagen fibrous protein in animal skins from putrefaction and produces hydrothermal stable product commonly known as leather. Thus study was conducted to improve the tanning efficiency of locally available tanning in the Sudan 'Garad', applying blending method, physico chemical properties of 'Garad', bark an...
This study is done to investigate the quality of water in Sodri in North of Kordfan and to see the effect of traditional mining on it’ s quality. Three samples of groundwater were collected according to standards methods:- One sample from the hafir and two samples from the wells. Samples were analyzed for physical and chemical parameters. A number of analytical techniques were used. Atomic Absorption Spectroscopy was used for quantification of elements namely iron, zinc, manganese an...
Abstract The environmental impact of traditional Gold mining activity has become a concern. The concern is due to the methods that are used in the extraction of the Gold from its co-metals, particularly the use of the Mercury. The purpose of the study to identify the impact of the traditional gold mining in Elcrow in Abo Hamad district. This research was undertaken to determine the concentration of toxic heavy metals that have been used to extract gold such as Mercury or has been released du...
Samples of Anogeissus leiocarpus gum were randomly collected as natural exudates from different locations of the Sudan gum belt. The physicochemical properties of composite samples studied were moisture content, ash, nitrogen, protein, specific rotation, relative viscosity, refractive index, density, also UV electromagnetic radiation, metals ions, pH, uronic acid, reducing sugars and infrared spectra. Analysis of variant of results showed insignificant dif ferences (p < 0.05) in all pro...
At the present work a simple, precise, accurate and economical reverse phase HPLC with UV detector method, was developed and validated for the simultaneous determination of acetaminophen and orphenadrine citrate in pharmaceutical formulations. better separation was achieved using cyanide column (250mm × 4.6mm, 5μm), maintained at 25 ͦC. The mobile phase was composed of (tri ethyl amine aqueous, methanol and acetonitrile) in the ratio of 50:20:30 (v/v/v), adjusted at pH 3.8 by ortho ...
Abstract In this research two types of activated carbon (AC) were prepared from Sudanese Nabag shells. The first one of AC was prepared by pregnating the shells with sulphuric acid before carbonization. The second type of AC was prepared without chemical treatment. The percentage yield of the products were calculated and found to be 32.31% for the AC treated with acid and 24.88 % for AC prepared without chemical treatment. The functional groups for the two carbons were determined by FT-IR te...
Sonchus oleraceus (moleita) from the family Asteracae was investigated for its radical scavenging activity. The whole herb was firstly extracted with dicloromethane to remove as much of chlorophyll and other colouring pigments. The plant residue was extracted with methanol. The methanol extract was tested for its antioxidative contents. The methanolic extract showed 88% radical scavenging activity against DPPH(1,1-Diphenyl-2-picyl hydrazyl) a reagent used to test compound for their abil...
Diabetes Mellitus result from insufficiency of insulin secretion or concomitant resistance to the metabolic action of insulin on target tissue, then hyperglycemia as developed. Alpha amylase is enzyme which hydrolyses starch molecules to give smaller polymers composed of glucose unit which cause increase blood glucose. Therefore analytical, case control and hospital base study conduct in Ahmed Qasum hospital in Bahri in Khartoum state (Sudan) during the period from March to Jun 2015 toc...
