The four different brands, Tianshi<sup>®</sup>, Qualitea<sup>®</sup>, Slimfit<sup>®</sup>, and Xiang<sup>®</sup> were purchased from a supermarket in Ihiala Local Government Area of Anambra State, Nigeria. The samples were pulverized and stored in an airtight container prior to analysis. The proximate composition was analysed using AOAC method while phytochemical compositions of the green teas were investigated using standard methods. The result of the study indicated that the moisture content (15.80±0.01%) and protein content (1.05±0.00%) of Qualitea<sup>®</sup> was significantly higher (P&lt;0.05) compared to Slimfit and Xiang tea while the fibre content of Xiang tea (80.35±0.03%) was significantly higher (P&lt;0.05) than other tea studied. The phytochemical study showed the presence of flavonoids, tannins, alkaloids, saponins and cardiac glycosides in all the teas studied. However, Qualitea<sup>® </sup>contains the highest amount of phytochemicals when compared to the other brands of tea investigated. Data obtained from the antioxidant mineral study showed that the four brands of the tea are good sources of antioxidant minerals such as Fe, Zn, Cu, Mn and Se. It is therefore recommended that tea be included in our menu because of their nutritive and health benefits.</p> Jonathan C Ifemeje Maryjane O Ifemeje Chukwuebuka Egbuna Michael C Olisah ##submission.copyrightStatement## 2020-02-01 2020-02-01 8 1 1 7 10.21467/ajgr.8.1.1-7 Utility of Biodiesel in Diesel Engine <p>The energy resources from the fossil fuels are decreasing day by day. Rather fossil fuel is costly, it creates environmental problems by producing&nbsp;and NO<sub>x </sub>in the environment. Now it is argent to find a solution. The solution can be renewable energy. In this paper the effort was to find the utility of biodiesels in the conventional diesel engine. This biofuel or biodiesel is extracted from Soybean methyl ester (SME). We compared the basic performance characteristics diesel, SME 20 and SME 100 in unmodified diesel engine. This experiment will be helpful to find out the utility of SME type biodiesel in conventional diesel engine so that the uses of fossil fuels can be reduced in quick rental power plants and other uses. We can use biodiesel as substitute in an economic tariff and efficient way.</p> Md.
