Significant Difference

Environmental pollution is a major issue which confronts industry and business in today’s world on daily basis. Industrial activities are the leading cause of metals emission, often associated with soil and plant metal concentration in adjacent regions. Cement industry is one of the 17 most polluting industries listed by the central pollution control board (CPCB). Impact of dust deposition from Cement Company of Northern Nigeria on the proximate and phytochemical concentrations of lettuce (Lactuca sativa) was studied. A comparative study of heavy metal concentration and phytochemicals of Lactuca sativa and soil samples from Kalambaina (Industrial area) and Kwalkwalawa (non-Industrial area) were estimated using atomic absorption spectrophotometry (AAS) and standard analytical procedures respectively. Result of quantitative phytochemical analysis revealed significant difference (P<0.05) in all parameters. Heavy metal values of Pb(0.012±0.002 mg/g), Zn(0.043±0.003 mg/g), and Ca(706.860±14.980 mg/g) in Lactuca sativa collected from Kalambaina revealed significant difference (P<0.05) when compare to samples collected from Kwalkwalawa and WHO standard. In addition, the heavy metal concentration in soil collected from Kalambaina showed significant difference (P<0.05) when compare to samples collected from Kwalkwalawa; with the highest value recorded in Ca (974.25±48 mg/g) which might be as a result of activities in the cement industry. Conclusively, plants grown at cement industries might not be safe for consumption

Aims: Nigerian indigenous kola nuts (Garcinia kola, Kola acuminate, Kola vera) were evaluated for potential phytochemical properties. Study Design: Phytochemical analysis. Place and duration of Study: Renaissance University, Ugbawka, Enugu State, Nigeria, July 2016. Methodology: The nuts were dried, ground and extracted by cold maceration with 99.5% methanol for 72 hours after which the methanol was allowed to evaporate. Results: The phytochemical evaluation revealed the presence of saponin glycosides, glycoside, volatile oil, steroid and alkaloid in Kola vera; saponin, saponin glycoside, glycoside, tannins, pseudo tannins, volatile oil, steroid and alkaloid in Kola acuminate while flavonoid, alkaloid and steroid were found in Garcinia kola. Conclusion: The phytochemical activities results showed that kola acuminate and Garcinia kola extracts exhibited more phytochemical than kola vera.

<p>The objectives of this reserch were to determine the antibacterial activity of hexane-petroleum ether (1 : 1 v/v) extract of Artemisia cinaBerg. ex Poljakov on Escherichia coli and Staphylococcus aureus and its compounds. The design of the research was using completely Randomized Design in five concentration of extract that were 0, 50, 75, 100, 150, dan 200 mg/ml with four repliceted. Ethanol 60% was used as negative control and tetracycline as positive control. There were three steps of research. First step was extracted the plant using soxhlet method with hexane-petroleum ether (1:1 v/v). Second step was determined the antibacterial activity of hexane-petroleum ether (1:1 v/v) extract in various concentration of that extracts on E. Coli and S. aureus using agar diffusion method. Analysis of Variance (ANOVA) and was used to determined the significan different of diameter of inhibition between the treatments. Thirdsteps was phytochemical analysis of extract. The highest antibactrial activity on E. Coli was at 100 mg/ml whereas on S. Aureus at 150 mg/ml. That extract was contained flavonoid, alkaloid, essential oils, saponin, sterol, tritepene, hydrolized tannin, and coumarin.</p>

Proximate and phytochemical analyses of the root extracts of Justicia carnea and Justicia  secunda in the Acanthaceae family were investigated using standard procedures and compared. The result of the proximate analysis indicated that the roots of both species contain nutrients in varying levels. Protein (11.38±0.01), lipid (4.81±0.01) and moisture content (17.01±0.01) were higher in the roots of J. carnea than in J. secunda (8.32±0.01, 2.01±0.01, 11.22±0.02) respectively, while Carbohydrate (6.62±0.00), Ash (16.75±0.05) and Fibre (55.18±0.01) were higher in J. secunda than in J. carnea  (4.73±0.02, 9.81±0.01, and 52.29±0.00) respectively. Qualitative phytochemical analysis showed the presence of tannin, flavonoid, alkaloids, saponin, phytate and cyanogenic glycosides whereas the result for the quantitative analysis showed that the quantity of phytochemicals in Justicia carnea and Justicia secunda were: tannin (46.75±0.00 and 41.01±0.01), flavonoid (2.72±0.01 and 3.21±0.00), alkaloid (10.16±0.00 and 11.21±0.01), saponin (3.31±0.01 and 2.7±0.00), phytate (30.54±0.01 and 33.86±0.00) and cyanogenic glycoside (100.01±0.00 and 500±0.00) respectively. Justicia carnea contained higher quantity of tannin and saponin while Justicia secunda contained higher amount of flavonoid, alkanoid, phytate and cyanogenic glycoside. These results conceivably indicated that the two species are good sources of essential nutrients which could be used in diets to supplement the daily nutrient needs in humans and animals, and phyto-nutrients which possess strong pharmacological activities, providing scientific credence for its therapeutic usage in folklore medicine.
