The study investigated proximate, nutraceutical composition and Antimicrobial activities of Uvaria chamea (Udagu) seeds. Standard methods were used to analyze the plant seeds for the present of nutraceutical and proximate component of the plant Uvaria chamea (Udagu) seeds. While disk diffusion method was employed to assay the the potent of the seed oil as an antimicrobial agent. Result of the proximate revealed that Uvaria chamea (Udagu) seeds contains ash (10.19 %), moisture (5.2 %), crude protein (0.09 %), crude fiber (51.81 %), total fat (26.19 %) and carbohydrate (6.52 %). While nutraceutical study showed that Uvaria chamea (Udagu) seeds contains cardiac glycosides (0.046 %), tannins (0.2 %), saponins (0.01 %) and alkaloids (0.45 %).The proximate result implies that the plant contains essential component such as crude fiber, total fat and ash in significant quantities, and can be utilized as food and in treating several ailments. The presences of alkaloids, tannins, Cardiac glycoside, and saponins in the plant seed indicate it can be used as a medicinal source. The oil presented no antimicrobial and antibiotic activities against Staphylococcus aureus and Salmonella typhi. The results suggest that Uvaria chamae seed have a potential role as a new source of health-promoting diets (can be used as a dietary fiber supplement in obesity management) with high oxidative stability. And the oil is a fixed oil that could be an acceptable substitute for cooking vegetable oil that do not have antimicrobial/antibiotic activities. Keywords: Proximate; nutraceutical; fiber; alkaloids; tannins

Zinc Oxide (ZnO) nanoparticles were synthesized by hydrothermal method and analyzed for various properties. Analysis of the XRD spectra of the synthesized nanoparticles showed 46 % crystalline zincite and the average grain size was calculated to be around 39.63 nm, studies of the FTIR spectra measured over the range between 4000–500cm−1 proved the presence of Zn Obonding of the synthesized nanoparticles at 734.26 to 1473.71 cm1 .SEMimage of the synthesized nano particles showed the formation of agglomerated nanoparticles of different shapes whose size are within the nanometer range while, cyclic voltamo gram of the immobilized ZnO nanoparticles on GCE also showed significant increase in redox peak current when compared to the bare (unimmobilized) GCE. It can be concluded from the obtained results that ZnO nanoparticles have been successfully produced which can be used to improve the performance of electrochemical sensors. Keywords :- XRD analysis, FTIR studies, SEM image analysis, Cyclic voltammogram

The objective of the study was to determine the active principles present and investigate if coconut husk charcoal used in traditional ulcer management adsorbs stomach acid (0.16 M). Simple chemical tests were undertaken to test for the phytochemicals. The coconut fiber charcoal was activated with 1M and 2M KOH and H2SO4 at 500 ℃ respectively in muffle furnace. Adsorption mechanism of stomach acid was studied by the adsorption of the acid onto an activated coconut husk charcoals. Adsorption which depends on contact time, amount of adsorbent and temperature is the transfer of stomach acid to the surface was determined by titrimetric method using 0.16 M NaOH and methyl red indicator. Five phytochemicals (alkaloids, carbohydrates, tannins, saponin and glycoside) were recorded present incoconut husk extracts. The result of adsorption mechanism revealed that KOH activated coconut husk charcoal is a better adsorbent than H2SO4 activated coconut husk charcoal. The optimum contact time (minutes) and amount (g) were found to be 15 minutes and 1g respectively. Temperature was found not to have any effect on the adsorption of stomach acid. The result of this study shows that KOH activated coconut husk charcoal can be effectively used in ulcer management. Keywords: Phytochemicals, coconut husk, activated charcoal, stomach acid, adsorption.
