| dc.description.abstract | Vernonia galamensis is one of only a few plants containing naturally occurring epoxy oils in its seeds known as vernonia oil. Seeds of vernonia galamensis produce triglyceride oil rich in trivernolin that can be converted into vernolic acid (72 - 80% of the seed oil). Carbohydrates are the most abundant organic compounds on the planet. They constitute a suitable replacement for fossil fuels since they contain a considerable amount of carbon and hydrogen. They are renewable natural resources, which are widespread and inexpensive, and from which a wealth of bulk of fine chemicals can be produced. The derivatives of carbohydrates with fatty acids have the potential to give value-added products and highly versatile materials with interesting characteristics. These compounds, derived from natural oils and carbohydrate, are used as surfactants in the food and cosmetic industries, as insecticides and antimicrobial agents. V. galamesnsis seed oil was first extracted, and methyl vernolate and fatty acid chloride were synthesized and allowed to react with carbohydrates such as glucose and cassava starch and the products were characterized using NMR. Keywords: Vernonia galamensis, methyl vernolate and amylopectin structure. | en_US |
