Seeds yield high percentage (46 to 53%) of a fixed oil. The oil principally consists of glycerides of ricinoleic, isoricinolic, stearic and dihydroxystearic acids, free ricinoleic, isoricinolic, stearic, linoleic, oleic and palmitic acids and a small quantity of palmitin and stearin. They also contain an alkaloid, ricinine and proteins consisting of globulin, albumin, nucleoalbumin, glycoprotein, a toxalbumin, ricin and some enzymes (Ghani, 2003). Seed coat contains 1.50-1.62% lipids and higher amounts of phosphatides and non-saponifiable matter than seed kernel (Rastogi & Mehrotra, 1993).
