The oil content of Trichilia emetica oilseed is 65%, much higher than most commercially grown oil seeds, and its high proportion of mono-unsaturated oleic acid provides good stability. The oil can also be used as a hair conditioner, a colorant, and applied to the skin. In addition, the oil is rich in essential fatty acids (palmitic, stearic, oleic and linoleic), which the body cannot synthesize naturally, but are vital in maintaining good health. The oil has been shown to have some antimicrobial and anti-inflammatory activity due to the presence of a number of limonoids, e.g., Trichilin A. My book covers many different issues of Trichilia emetica seed oil, and is devoted to those students and scientists from many different disciplines who might seek quick reference to an essential point. In this way it provides the reader with concise, up-to-date information, as well as including many new references for those who wish to obtain a deeper insight into any particular issue.
