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...

ANALYSIS OF DIFFICULTY LEVEL OF THE COURSE IN NIGERIA CERTIFICATE IN EDUCATION (NCE) CHEMISTRY CURRICULUM: PRE-SERVICE TEACHERS PERSPECTIVES IN GOVERNEMNT OWNED COLLEGES OF EDUCATION IN ENUGU

INTRODUCTION Chemistry is one of the essential science subjects. According to Oxford Advanced Learners Dictionary (2008), chemistry is the branch of science that deals with the composition and properties of substances and various elementary forms of matter. Mifflin (2011) defined chemistry as the science of the composition, structure, properties and reactions of matter especially of atomic and molecular systems. Sarah (2015) defined chemistry as a physical science and the study of the pr...
