|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.|
