During the past decade, almost all of the energy studies were on important alternatives such as oil, coal, solar, nuclear, etc. It is for this reason that environmentalists are entrusted to examine a very wide range of human needs towards indigenous resources that would ‘somehow assist in our nation’s falling supply of energy. Various organic oils and fats are essential constituents of all forms of plants and animals. However, only relatively few plants and animals produce fats and oils in sufficient quantity. The most important oil, therefore, are those that can be readily attained in commercial quantities from available raw materials. Organic oils are triglycerides or esters of fatty acids. They are chemical combinations of one molecule of glycerol with three molecules of fatty acids. When processed with caustic alkalis, they form soaps that are salts of fatty acids and glycerol, which is tryhydric alcohol. Yellow bell is a shrub with small, elongated branches and narrow alternate leaves. The plant requires direct sunlight. Quisumbing (1978) mentioned, that the the vetin seeds yield a fixed oil that contains triolein (63 percent), tripalmitin and stearin (37 percent).
In regulated doses, the decocted bark is employed as emetic and febrifuge, being said to be effective in intermittent fevers. The bark is also antiperiodic in small doses, and the leaves are used as a cathartic. Liquid fuel is important for power generation. It is fuel oil. It is classified according to its properties, e.g., flash point, pour point, percent-age of water and sediment, carbon residue, ash distillation temperature, and viscosity. When processed with simple methods, the utilization of the yellow bell seeds will yield oil that shows the same chemical properties of fuel.
