It also aims to assess the potential of the oil as a biomass for the production of biofuel that can be used as an alternative to regular petrol fuel. Therefore, this thesis comprises two main sections, the first concerns with the chemical and biological properties of castor oil as well as the major fatty acid in the oil which cauld be obtained via hydrolysis of the oil triglycerides,ricinoleic acid.The second section, on the other hand concerns with the potential of castor oil as a biomass for the production of biofuel that can be used as an alternative to regular petrol fuels. In the first section, the chemical and physical properties of the oil have been determined and evaluated. In addittion the antimicrobial as well as the anticancer activity of the oil as well as ricinoleic acid have been studied. The results showed that castor oil is less effective as antimicrobial agent than ricinoleic acid while the reverse is true regarding their effects as anticancer agents. It has been also proved that both of ricinoleic acid and castor oil are more effective as anticancer agents on liver cancer than that on colon and breast cancer ER -
