in order to evaluate the density and dry weight of weeds and seed and oil yield of castor bean ricinus communis l.) as a medicinal plant affected by cover crops, an experiment was conducted at the agricultural research station, faculty of agriculture, ferdowsi university of mashhad, during growing season of 2008-2009. treatments were four cover crops included white clover, fenugreek, hairy vetc...

The castor seed contains ricin, which is one of the most potent biological toxins and is widely considered to be a threat agent for bioterrorism. In this study, a rapid and sensitive PCR method was applied to the detection of castor contamination in milk and liquid egg samples. The targeting gene sequence of the primer set, Ricin-F4/R4, was not found in either the bovine or chicken genome. Prim...

Statement of the Problem Researchers always seek a new storage medium for avulsed teeth. Castor oil is a vegetable oil with several advantages such as antimicrobial and antioxidant properties, low toxicity, and glutathione preservation capability, low cost, and high availability. Purpose The purpose of this study was to evaluate and compare the capacity of castor oil as a new storage medium i...

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...

castor bean, peanut, soy bean and safflower protein isolates were prepared. the amino acid content of each of the protein isolates was analysed and the essential amino acid contents were compared with the fao human requirements. the results indicated that castor bean has the highest oil and the protein content of defatted meal. safflower 3148 (marand, iran) has the highest amount of essential a...

Castor, (Ricinus communis L.) is one of the most important commercial, non-edible oilseed crop. Tobacco caterpillar, Spodoptera litura (Noctuidae: Lepidoptera), a major defoliator castor. The biophysical factors in castor play role conferring resistance against S.litura. present study was conducted with an objective, to basis S. litura. Feeding preference larvae leaves IVHT-39 followed by Salem...

The anti-diarrheal activity of the alcohol and aqueous extracts of the roots of Dodonaea viscosa (Sapindaceae) was investigated by castor oil induced diarrhea in mice. The parameters of this study were number of diarrheal episodes and mean weight of stool of mice. The percentage protection in extract treated animals showing diarrhea was compared with castor oil treated and loperamide treated an...

Hypoalbuminemia in the absence of hepatic, renal, and nutritional deficiency may indicate protein malabsorption or protein losing gastroenteropathy. Abuse of laxatives like castor oil can cause protein losing gastroenteropathy(l). Castor oil is hydrolyzed in the intestine by pancreatic lipase to glycerol and ricinoleic acid. Ricinoleic acid acts as a mild irritant and causes purgation. It is al...

Leupeptin, a tripeptide inhibitor of some proteinases, was shown previously to maintain the stability of several enzymes (isocitrate lyase, fumarase, and catalase) in crude extracts of castor bean endosperm. This reagent is now shown to inhibit the breakdown of water-soluble and crystalloidstorage proteins of the protein bodies isolated from castor beans by the SH-proteinase and it also inhibit...
