ANTIMICROBIAL AND PHYTOCHEMICAL ACTIVITIES OF Datura stramonium (GEGEMU LEAVES)

1.0 INTRODUCTION Daturastramoniumis an annual herb, with stem erect and spreading branches above. It is common in the waste land, fields and gardens in Baghdad district. Leaves, seeds and roots contain the alkaloid daturine (a mixture of the two alkaloids hyoscyamine and atropine) and also contain scopolamine alkaloid (Hyosine) acids, tannin and fatty oil. Plants are rich source of secondary metabolites with interesting biological activities (Palombo and Semple, 2001; Koduruet al., 2006)...

Application of Chemometric Technique in the Determination of the Chemical Facies of Groundwater Pollution Assessment in the Shallow Marine Aquiferous Sandstone in Udi and Environs

ABSTRACTThis paper examines the hydrochemical facies of groundwater present in the shallow marine Plain Sands aquifer of Udi and its immediate environs, maps their areal distribution and attempts to explain the controlling processes responsible for the various facies. 12 water samples were collected from wells tapping the shallow marine Plain Sands aquifer of Udi and environs and analyzed for various parameters including pH, total dissolved solids (TDS), K, Na, Ca, Mg, Cl, NO3, Fe, Pb, TH, Ac...

Studies On The Blastofiltration Potentials Of Selected Plant Seeds For The Treatment Of Lead And Cadmium Contaminated Water Samples

ABSTRACTPhytoremediation, based on the theory of botanic tolerance and accumulation of certain pollutant, is a new developing ecological technique primarily used to clean polluted environment. Blastofiltration is applied to phytoremediation of heavy metal polluted water at present. The study used castor, okra, melon and moringa seeds as experimental materials to investigate their potentials as possible blastofiltration materials. The results showed that with the trial time lasting up to 72 ho...

Synthesis, Characterization And Antibacterial Properties Of Nickel (Ii) Amine Malonate And Nickel (Ii) Amine Tartarate

ABSTRACTNickel amine carboxylate complexes were synthesized by reacting Ni(ii)chloride with ammonia, malonic and tartaric acid, which formed Nickel amine malonate and Nickel amine tartarate  of  blue and green crystal and  the percentage yield are of both complexes are 62.65% and 62.83% respectively. The decomposition temperatures were 218o C and 203oC with percentage moisture content of 8.0% and 21.50%. The carboxylic acids and the synthesized complexes were tested for antibac...

Determination Of Heavy Metals In Some Cosmetic Products Commonly Used Among Students Of Kaduna Polytechnic

ABSTRACTThe toxicity of heavy metals to humans as a result of long term exposure to pollutants consumer products such as cosmetics and other pollutants has been established. In this study, the levels of heavy metals in different cosmetic products commonly used among Kaduna Polytechnic students were assessed. The cosmetics were analyzed for heavy metals (chromium, copper, nickel and lead) using Atomic Absorption Spectrophotometer (AAS) after digestion with concentrated   HNO3 and HCl acid...

Chemical composition and biological activity of Allium sativum essential oils against Callosobruchus maculatus

ABSTRACTIn order to search for alternative control methods to synthetic pesticides, the potential of essentialoils from Allium sativum (L.) (Alliaceae); was evaluated as fumigants against Callosobruchus maculatus (fab.)(Coleoptera: Bruchidae), a pest that attacks pulses during storage. Chickpea seeds were infested with 10 pairsof newly emerged weevils and, fumigated with 0, 1, 2, 3, or 4μl of essential oils of garlic/l of air. The essentialoils of garlic were analyzed by GC-MS. The major com...

Effect of dye and bleaches on hair

1.0    INTRODUCTIONHair coloring is the practice of changing the hair color. The main reasons for this are cosmetic, to cover gray hair, to change to a color regarded as more fashionable or desirable, to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching. Hair dyes generally contain dyes, modifiers, antioxidants, alkalizers, ammonia and a mixture of other compound used to impart different qualities to hair depending on the ha...

PRINCIPLES OF CARBON-U (C-11) RADIO-CHEMISTRY

ABSTRACTCarbon –U (C-11) radiotracers are widely used for the early diagnosis of cancer, monitoring therapeutic response to cancer treatment and pharmacokinetic investigations of anticancer drugs. PET imagining permits non-invasive monitoring of metabolic processes and molecular targets, while carbon-II radiotracers allow a “hot-for cold” substitution of biological active molecules. Advance in organic synthetic chemistry and radiochemistry as well as improved automated techniques for ra...
