    Determination of Caffeine and pH Levels of Selected Carbonated Soft Drinks and Ready to Drink Juices in Eldoret, Kenya.
    (International Journal of Innovative Research in Engineering & Science, 2013-05) Magut Hillary; T. Anthoney Swamy; Terer Erick Kipngetich
    Different brands of soft drinks and selected ready to drink juices were randomly sampled from different stores in Eldoret town. Two methods of extraction were employed; hydrochloric acid acidified water and distilled water. UV analysis results of acidified water samples, the caffeine levels were found to be in the range of 1.43 mg/L and 40.51 mg/L, the lowest being Stoney and the highest being Coca-Cola respectively. With distilled water alone, the concentration ranged from 1.51 to 39.65 mg/L, these being Stoney and Coca-Cola respectively. Ready to drink juices showed the highest levels of caffeine content in both distilled and acidified water extraction with the lowest reading of 59.43 mg/L obtained from Pineapple Marche brand while the highest concentration was from orange Marche brand with 75.71 mg/L caffeine in acidified water extraction.

    Determination of levels of phosphates and sulphates in domestic water from three selected springs in Nandi County, Kenya
    (INTERNATIONAL JOURNAL OF PHARMACY & LIFE SCIENCES, 2013-07) Terer Erick Kipngetich; Magut Hillary; T. Anthoney Swamy
    This research was to estimate the levels of phosphates and sulphates in three selected springs. The analysis of phosphates requires good digestion which converts phosphorus to orthophosphate in the process. Therefore, ascorbic acid digestion method was employed in the phosphate analysis. The sulphates spectrophotometric analysis is based on the formation of colloids by sulphates and Barium chloride. With this method the greatest challenge was instability of conditioning reagent with time. Several timing trials were done to come up with the optimum time for reaction between the addition of conditioning reagent and sample analysis. Sampling was done at selected springs in Baraton Location, Sironoi Location and Kaptildil Location, all situated in Chesumei Constituency, Nandi County, Rift valley province in Kenya. The selected water springs are commonly used by residents for domestic purposes. The research showed that there is a significant level of phosphates and sulfates in all sampled water. Phosphates concentration were between the range of 2.79 mg/L to 622 mg/L, while sulphates were in the range of 109.8 mg/L to 250.98 mg/L.

    In Vitro control of selected pathogenic organisms by Vernonia adoensis roots
    (INTERNATIONAL JOURNAL OF PHARMACY & LIFE SCIENCES, 2013-08-01) T. Anthoney Swamy; Obey Jackie; Ngule Chrispus Mutuku
    The main aim of conducting this study was to evaluate antibacterial activity of methanol–water extract of Vernonia adoensis roots against Salmonella typi, Klebsiella sp, Bacillus cereus, Streptococcus pyogenes, E. coli, Proteus vulgaris and Enterobacter aerogenes.The roots powder of the plant were extracted with methanol and water in the ratio 9:1. The antibacterial activity of the extract was determined by agar well diffusion method. Vernonia adeonsis roots extract was found to control the growth of only B. cereus, S. pyogenes and Proteus vulgaris at zone of inhibition of 10.50 ± 0.563, 15.67 ± 0.422 and 11.00 ± 0.577 respectively. From the study methanol- water extract can be used to control B. cereus, S. pyogenes and Proteus vulgaris. More research needs to be done to identify the specific bioactive compounds, their structural formulas, their mode of action and toxicity in vivo conditions.

    Physico-Chemical Study of Soil from Selected Maize Farms in Kamelilo, Kericho County
    (Int.J.Curr.Microbiol.App.Sci (2015) 4(10): 438-447, 2015) T. Anthoney Swamy; Terer Erick Kipngetich; Barasa Exevier; Magut Hillary
    Physico-chemical study of soil was performed in this study to determine the levels of different physical and chemical parameters in seven selected maize farms. A total of 21 samples were collected in ploughed maize farms in Kamelilo Village in Kericho County for physico-chemical study. Samples were obtained from seven selected maize farms in triplicates. The physical parameters that were studied are pH and organic carbon while the chemical parameters like phosphorus, Sulphur and Nitrogen were determined. From the study, 71% of the soil samples had a low pH which makes the soil unsuitable for maize farming. The recommended pH for maize growing is 5 7 which has a positive effect on the availabilty of nitrogen and other plant nutrients. The percentage of organic carbon was rated as high in 90% of the soil samples with a minimum value of 1.03% organic carbon to a maximum value of 2.85% except in two sampling sites, sample 3a with 0.45% and sample 5a with 0.49% respectively exhibiting a low organic carbon value. It is the recommendation of the researchers that regular soil testing should be done to determine if the soil is in the ideal condition for a specific crop.
