The castor plant Ricinus communis L., Euphorbiaceae produces seeds containing a unique oil. Castor oil is the only commodity vegetable oil that contains significant amounts of hydroxy fatty acid. This fatty acid is ricinoleic acid (12-hydroxy oleic acid) (Fig. 1) and it comprises up to 90% of the total fatty acid (FA) content of castor oil. Due to the physical and chemical properties imparted b...

dried figs collected from various exporting companies (2,461 samples) and local stores (219 samples) were analyzed using reverse-phase high-performance liquid chromatography (rp-hplc) to determine and compare the incidence of aflatoxins, the effectiveness of the regulation limits and monitoring system to select non-compliant samples and the mean daily aflatoxin exposures. the incidence rates of...

Castor is an important oilseed crop with great utilitarian value in industrial, pharmaceutical and agricultural sectors, the major constituents of seeds are lipids, carbohydrates, proteins and, course, nucleic acids. Seed deterioration associated various cellular, metabolic chemical alterations to seed constituents. The objective this study was determine effects induced ageing on nutrient conte...

objective: castor (ricinuscommunis l.) is an industrial oilseed that belongs to the family euphorbiaceae. castor is believed to be originated in east africa probably ethiopia. although ethiopia is known as a primary diversity for castor the knowledge on nature and extent of variation of the indigenous germplasm is limited. the present test was conducted to study the nature and extent of variabi...

Degradation of unusual fatty acids through β-oxidation within transgenic plants has long been hypothesized as a major factor limiting the production of industrially useful unusual fatty acids in seed oils. Arabidopsis seeds expressing the castor fatty acid hydroxylase accumulate hydroxylated fatty acids up to 17% of total fatty acids in seed triacylglycerols; however, total seed oil is also red...

BACKGROUND Ricinus communis (castor bean) is a species included into the Euphorbiaceae family, common to all the warm regions of the world. Although the allergenicity of its seed is well known, references are scarce regarding the role played by its pollen as a pneumo-allergen. OBJECTIVES To carry out an aerobiological study of this pollen in the Málaga area (southern Spain); describe the phys...

The effects of plant species (castor bean (Ricinus communis L.) versus sunflower (Helianthus annus L.)) and irrigation regime (freshwater versus secondary treated municipal wastewater) on soil properties and on seed and biodiesel yield were studied in a three year pot trial. Plant species were irrigated at rates according to their water requirements with either freshwater or wastewater effluent...

Testosterone undecanoate (TU) dissolved in soybean oil was developed in China to improve the pharmacokinetics of this testosterone ester in comparison with TU in castor or tea seed oil. As a pre-clinical primate model, three groups of five castrated cynomolgus macaques received either a single intramuscular injection of 10 mg/kg body weight TU in soybean oil, in tea seed oil, or in castor oil (...
