Extraction and Characterization of Castor Seed Oil from Wild Ricinus Communis Linn
Castor oil was extracted by mechanical cold pressing (< 45 0 C) of the seeds of wild castor plant (Ricinus communis L.) found in wet marginal lands of Katsina, Nigeria. Oil yield was 39.43%. The virgin oil (obtained as clear, viscous, pale-yellow liquid) was further purified by filtration through sintered glass (fine mesh screen). This was to eliminate any dust, gum, or other particulates prese...
متن کاملBone Regeneration after Demineralized Bone Matrix and Castor Oil (ricinus Communis) Polyurethane Implantation
Innocuous biocompatible materials have been searched to repair or reconstruct bone defects. Their goal is to restore the function of live or dead tissues. This study compared connective tissue and bone reaction when exposed to demineralized bovine bone matrix and a polyurethane resin derived from castor bean (Ricinus communis). Forty-five rats were assigned to 3 groups of 15 animals (control, b...
متن کاملMetal Concentration in Plant Tissues of Ricinus communis L. (Castor Oil) Grown In Soil Contaminated With Spent Lubricating Oil
Castor oil plant seeds (Ricinus communis L.) were grown in spent lubricating oil (SLO) contaminated soil at concentrations of 1-6% (w/w, oil/soil). Plant height and stem girth were depressed by spent lubricating oil at concentrations of 2% (w/w) and above. One percent (1%) spent lubricating oil in soil promoted growth of plants when compared with control. Fresh and dry weights of R. communis pl...

متن کاملChemical Investigations of the Castor Bean Plant Ricinus communis
In 2009 a National Security Science and Technology grant was awarded to the Human Protection and Performance Division for the investigation of several forensic aspects of the castor bean plant Ricinus communis. A major focus of this grant was to understand the chemical composition of the seeds, and to ascertain if these differences could be used for provenance classification. This technical rep...
