The pondered parts (mixture of fresh leaves, twigs & soft stem barks and soft root extract) of Annona senegalensis plant have been used as ethno-medicine for treating patients suffering from tinea versicolor. The antifungal activities of dichloromethane and methanol (1:1), methanol, water, acetone, ethanol, ether and chloroform extracts of Annona senegalensis (Annonaceae) parts were investigated and primarily assessed against cultured Malassezia globosa fungus isolated from willing tinea versicolor patients. The efficacy of the extracts was studied and determined by applying different extracts concentrations on agar slants carrying the fungus in an incubator. The susceptibility of tested fungus on the extracts was determined by measuring the diameter of inhibition zones formed around the disc. The highest anti-fungal activity was observed in methanol fresh leaf extract gave an inhibition zone of 9.667 ± 0.557 mm while methanol twigs and soft bark extract gave lowest inhibition zone of 4.333 ± 0.5773 mm compare with gentamycin which gave an inhibition zone of 15 mm after 24 hours. Thus combination of the mixtures confirms the antifungal synergistic interaction against the Malassezia globosa fungus. The water, acetone, ethanol, ether and chloroform plant extracts showed no inhibition zones hence proved ineffective at the evaluated concentrations. The preliminary phytochemical screening of the plant parts also indicated the presence of the relevant phytochemical constituents, thus supports its medicinal values.

Majority of the Island inhabitants depends on groundwaters for drinking therefore the hydrogeochemistry and health risks assessment with respect to WHO standards is absolutely essential for protection policy formulation. The groundwater samples for analyses were collected from selected four wells within each (Chukwani-Mbweni, DarajaMbovu - Amani and Mwanakwerekwe) suburb during the moderate rainy season of January2020.The selection was based on their strategic positions taking into consideration relevant geographical and environmental factors commensurable with this study. Various contaminants and physiochemical parameters were determined using Atomic Absorption spectroscopy, GC/MS, Temp/pH/TDS/EC meter and DR/3900 spectrophotometer. Chemical Oxygen Demand values were also determined. Microbial contamination was determined using the MPN technique. The results shows that these groundwaters are slightly alkaline, microbially contaminated, have high C.O.D. values ranging from 188.5 to 305.7 mg/L indicating the existence of some organic based endocrine disruptive elements, and disparities in water quality parameters with respect to the recommended WHO standards thus ascertaining possible public health risks. The research recommends the need for continuous monitoring, assessment and treatment of these raw groundwaters for drinking at the point of collection rather relying on the old conventional boiling method or drinkingas it is.

Cases of synergic Urinary Tract Infections with its associated ailments has become a menace. Due to its high costs of treatment, unavailability of relevant antibiotics, misdiagnosis and recurrence, most patients within Africa Sub-Sahara regions prefer ethnopharmacological ways of taking boiled and sieved liquid concoction made from mature leaves (ML) of ricinus communis to clear the urinary tract system from these microbes with their associated ailments. Crude extracts of methanol, chloroform, hexane, and Diethylether prepared from ricinus communis dried powered mature leaves were subjected to phytochemical screening, antibacterial, GC/MS and antioxidant assays. Crude methanolic and chloroform extracts prepared from a mixture of coarsely powdered dried twigs and mature leaves were evaluated for cytotoxic activity on cancer cell line (HCT-116 and K-562). Antibacterial assay of the crude extracts reveals recommendable range of values categorized as moderate and high sensitive with respect to the standard measure. Methanol extract exhibited antibacterial activities against all gram-positive and gram-negative bacterial species while diethylether extract showed its potency against the gram-positive staph only among escherichia, klebsiella and pseudomonas species. Chloroform, diethylether and hexane crude extracts proven to be inert against pseudomonas strain. Highest scavenging capacity range obtained is 60.38 ± 0.034 percent while the lowest cytotoxicity range is 20.18 ± 1.37 μg/ml-1revealing the medicinal value and safeness of the plant extract. Phytochemical analysis and GC/MS results revealed the presence of phytoconstituents and museum of bioactive agents with antibacterial, antifungal, antiviral, anti-inflammatory, anticancer, antidiarrheal, antimutagenic and anti-oxidant properties thus ascertaining its efficacy towards the infection with associated ailments.
