Abstract
This experiment was carried out on the leaves, seeds, and burrs pericorps of local Iraqi castor bean . It consisted of two parts, the first concerned with the active naturally occurring compounds in plants. The second part concerned quantitative and qualitative estimation of the essential and active constituents in the leaves ,seeds and burrs. The primary test showed that the leaves, contained : glycosides, tannins, resins, coumarins, alkaloids are positive results. However, with saponins and flavones are negative results. the seeds showed positive results with tannins, comarines, terpines, steroids, and negative result with others. The burrs of castor showed positive results with tannins, glycosides, saponins, coumarins, and negative result with others. The water extract was acidic pH : 5.71, 8.71, 5.52. The percentage of essential constituents of leaves , seeds ,burrs , were found that the oil percentage 2.1 , 53 and 1.2 , protein; 13.5 , 14.28 and 10.5 , Moisture : 12.8 , 7.81 and 9.6 , tannins : 6.7 , 8.9 and 10.5 , crude fiber ; 15.6 , 16.1 and 17.6 , total ash ; 12.15 , 19.5 and 13.5 , ash soluble in water: 30.33 , 33.5 and 29.33 mg/g , and ash insoluble in acid 21.25 , 22.61 and 19.5 mg/g . The experiment, of measuring the degree of swelling of leaves ,pulps and burrs under room temperature, in dark and during equal periods of time; the leaves required 2-4 hours for reaching degree of swelling and then to equilibrium , whereas the seeds elapsed about 48 hours and the burrs 12 hours .
