Castor plant (Ricinus communis L.) produces a unique seed oil with numerous industrial applications. However, castor seed contains toxin ricin and hyper-allergenic 2S albumins detrimental to castor grower and processor. Our project goal is to develop a safe source of castor oil through genetic engineering. The general approach is to generate a safe castor crop by blocking expression of the rici...

Seed maturation or seed filling is a phase of development that plays a major role in the storage reserve composition of a seed. In many plant seeds photosynthesis plays a major role in this process, although oilseeds, such as castor (Ricinus communis), are capable of accumulating oil without the benefit of photophosphorylation to augment energy demands. To characterize seed filling in castor, a...

The crude oil of Malaysian castor bean ricinus communis L. seed was extracted by Soxhlet method using hexane. The physicochemical characteristics of castor bean oil were evaluated. The results showed that Malaysian castor seeds contain a relatively high percentage of total lipids content; 43.3% (per dry weight), high iodine value (84.5 mg/g) and saponification value (182.96 mg/g). The seed oil ...

Castor (Ricinus communis L.) is an important non-edible oilseed crop that can potentially be used as feedstock for biodiesel production. There are 1033 accessions in the United States Department of Agriculture (USDA) castor germplasm collection. The range of oil content in these accessions has never been surveyed. For exploiting castor as a feedstock for biodiesel production, the entire USDA ca...

Native de-oiled and treated castor seed meal was subjected to proximate analysis and quantification of anti-nutrients (phytochemicals). Seed cake was treated by biochemical technique of solid state fermentation with Aspergillus niger and addition of calcium oxide (CaO) to give treated castor seed meal (TCSM). One hundred and twenty Japanese quails (Coturnix coturnix japonica) were fed four (4) ...

An experiment was carried out to evaluate the effects of irrigation levels, based on fraction of the class A Pan evaporation 0.8, 1.00 and 1.20% of ECA and spraying of different amount of salicylic acid (250and 500 Mm) and sprmine (10 Mm And 1 mm) on grain yield and seed quality characteristics of castor bean in during 2012 seasons. The experiment was split plot as randomized completed block d...

Healthy and bold seeds of castor variety “Aruna” were collected. The de-hulled castor kernels were separated from seed coat and finely grounded in an electric grinder. The powdered kernels were passed through 60 mesh sieve and defatted using n-hexane in a soxhlet extractor. After complete extraction of oil seed meal was made free from solvent at low temperature. The defatted seed meal was pulve...
