Leucaena leucocephala is a fast-growing leguminous plant this is used in the treatment of intestinal diseases and as birth control. This work was geared toward investigating the phytochemical attributes and the antimicrobial actions of methanol and distilled water crude extracts from the stem bark of Leucaena leucocephala in the ratio of 3:2 on nineteen bacterial species. The antimicrobial activity of the plant extract was done with the use of the agar diffusion technique in line with the National Committee for Clinical Laboratory Standards. The extract was located to be energetic against sixteen bacterial traces at a concentration of 35 mg/mL except for Bacillus anthracis, Clostridium sporogenes, and Pseudomonas fluorescens . The zones of inhibition exhibited by means of the extract towards the organisms ranged from 10.00 mm to 20.00 mm. The MIC exhibited by the extract ranged from 2.19 mg/ml to 8.75mg/ml while the MBC ranged from 4.38 mg/ml to 17.5 mg/ml. The effects of the extract on bacterial species were compared with the use of selected antibiotics such as streptomycin, and ampicillin. The phytochemical parts of the extract include tannins, glycosides, alkaloids, phenols, and terpenoids. Results from this research confirmed that the stem bark extract of Leucaena leucocephala exhibited antimicrobial activity against the selected bacteria and support the usefulness of this plant in folklore treatments.

The rise in the incidence of side effects of many synthetic antimicrobial agents and prevalence of multidrug resistant bacteria has spurred scientists on the research for plant based antimicrobial of therapeutic potentials. Ocimum gratissimum L. presents such potential of high medicinal value. This plant is used in Nigeria traditionally as condiments and for treatment of various ailments. This study is aimed to determine the phytochemical and antimicrobial property of ethanol and aqueous extracts of O. gratissimum L . leaves. Phytochemical screening of the leave extracts confirmed the presence of Steroid, Tannins, Flavonoid, Terpenoid, Alkaloid, Saponin and Phlobatannis. Ethanol and aqueous extracts were obtained from the powdered leaves of O. gratissimum using ethanol and distilled water respectively. These were later filtered and the filtrates were concentrated in water bath at 50 o C. Mueller-Hinton agar was used for the antibacterial susceptibility using the agar well diffusion method. For ethanol extract, all the isolates were susceptible at 0.2g/mL, 0.1g/mL and 0.05g/mL concentrations. However, for aqueous extract, all the isolates were resistant at 0.05g/ml and 0.025g/ml but at 0.2g/ml concentration all the isolates were susceptible. Staphylococcus aureus was resistant at 0.1g/ml, except Pseudomonas aeruginosa and Bacillus cereus which were susceptible with a diameter 15mm, and 14mm respectively. Ciprofloxacin used as positive control also inhibited the growth of the bacterial isolates with the diameter of zone of 25mm. Results obtained from this study showed that the extracts of Ocimum gratissimum L. has antibacterial activities against the selected gastrointestinal tract pathogenic bacteria and also possess some bioactive compounds.

River Owo is a polluted water body in Agbara Industrial area an outskirts of Ojo Local Government Area due to the dumps of industrial wastes. The body contains diverse soluble and insoluble both of organic and inorganic compounds as well as living organism such as benthic macroinvertebrate fauna. This research work is an intensive studies carried out on constituents of river and compared with Iba stream of no active polluting activities in the same Local Government as a control. Water and macro invertebrate samples were taken from the two sites. Physicochemical and heavy metals analysis were carried out on the water using Atomic Absorption Spectrophotometer. The invertebrates were quantitatively and qualitatively analyzed. I nvestigations revealed that the water body is slightly acidic with pH of 5.5 to 6.5. It hardness have been mild due to the impact of the constituents that have softened it to extents of about 88mgL -1 . Sulphate level of range 0.07 to.09mgL-1 is significantly low. These physicochemical factors did not contribute adversely to the two water bodies. However, high BOD of 340 to 357 above the limit 30 indicated that the pollution of River Owo mainly comes from organics waste dumps. Decapods such as Palaemonetes sp and amphipods which are common to polluted environment are found in River Owo. The abundance of various forms of insects of which dragon fly nymph Palemonetes sp were most in population are found around River Owo. Therefore River Owo is mainly being polluted with organics substances. However both Physicochemcal parameters and Benthic studies Iba stream indicated that it is free of pollution. This could have been due to the disallowed dumps of domestics and industrial wastes were not allowed into the stream.
