castor oil due to extraordinary physicochemical properties has numerous applications in pharmaceutical, chemical, hygienic, biodiesel and nowadays in food industries. during plant growth and development, as well as during postharvest and processing, different factors may affect caster oil properties. this study was conducted to evaluate oil content and physiochemical properties under different ...

The extraction of Castor oil was accomplished by mechanical cold pressing the seeds wild castor plant (Ricinus communis) found in Ini Local Government, Area Akwa Ibom State, Nigeria. Oil yield 38.69%. virgin (obtained as clear, viscous, pale-yellow liquid) further purified filtration through sintered glass (fine mesh screen). This to eliminate any dust, gum, or other particulates present. Physi...

of conversion of fat to carbohydrate in germinating castor beans. Of the four requisite enzymes, isocitritase (Equation 3) has been demonstrated by direct assay (l), while the presence of condensing enzyme (Equation 1), aconitase (Equation 2), and malate synthetase activity (Equation 4) has been inferred from isotope incorporation data. The rates of condensing enzyme and malate synthetase, as e...

introduction castor plant, ricinus communis l. is a species of flowering plant in the spurge family; euphorbiaceae, which contains a vast number of plants mostly native to the tropics. it belongs to a monotypic genus ricinus. the name ricinus is a latin word for tick. the plant is probably named because its seed has markings and a dump at the end that resemble certain ticks (ncri, 2014). castor...

Ribosome-inactivating proteins (RIPs) are enzymes that inhibit protein synthesis after depurination of a specific adenine in rRNA. The RIP family members are classified as type I RIPs that contain an RNA-N-glycosidase domain and type II RIPs that contain a lectin domain (B chain) in addition to the glycosidase domain (A chain). In this work, we identified 30 new plant RIPs and characterized 18 ...

Cotton is one of the most important commercial crops in India, playing a key role in national economy. Short duration and high yielding varieties are always required for better quality and lint production. Early maturing crops avoid disease and pest epidemics due to which plant breeders have positioned adequate pressure on the development of early maturing crop plants (Singh, 2004). Term earlin...

The membrane components of the castor bean spherosomes were characterized. The storage triacylglycerols of isolated spherosomes were extracted with diethyl ether, and the membrane was isolated by sucrose gradient centrifugation. It had an apparent equilibrium density of 1.12 grams per cubic centimeter, and possessed an antimycin A-insensitive NADH cytochrome c reductase and an acid lipase. Phos...

The amounts of the two lectins (ricin and Ricinus communis agglutinin) in tissues of castor bean seedlings were followed during germination and early growth. For measurement, lectins in extracts were separately eluted from Sepharose columns; an antibody to the agglutinin was also used to detect the lectins by immunodiffusion. The endosperm of the dry seed contains 3.5 mg total lectin (5.6% of t...
