Ricinus communis L. is of great economic importance due to the oil extracted from its seeds. Castor oil has been used for pharmaceutical and industrial applications, as a lubricant or coating agent, as a component of plastic products, as a fungicide or in the synthesis of biodiesel fuels. After oil extraction, a castor cake with a large amount of protein is obtained. However, this by-product ca...

background: nowadays colonoscopy has a very important role in screening colorectal cancers. in addition, adequate bowel preparation is critical to colonoscopy, as a poor preparation may obscure pathology or prevent full colonoscopy. as it is estimated that unsuccessful colonoscopy leads to second procedures in up to 20% of patients, we sought to compare the effects of different doses of polyeth...

The experiment of methanolic extract of Microcos paniculata leaves showed significant (p<0.001) inhibitor activity against castor oil induced diarrhea and castor oil induced enteropooling in mice at dose of 400 mg/kg body weight. There was also significant (p<0.01) reduction in gastrointestinal motility in the charcoal meal test. Loperamide (5 mg/kg b. wt) was used as positive control. These re...

Denture hygiene is essential because denture biofilm is involved in oral infections and systemic diseases. Although there are chemical agents available on the market, none of them have ideal properties and research on such products is still necessary. The aim of this study was to evaluate the efficacy of a castor bean (Ricinus communis)-based solution for removing denture biofilm, compared to t...

introduction: artemisia dracunculus l. belongs to asteraceae family, and is a medicinal plant widely used in traditional medicine as a remedy for gastrointestinal disturbances. this study was undertaken to evaluate the effects of essential oil of a. dracunculus (eoad) on the rat alimentary tract. methods: the eoad was extracted by clevenger apparatus using hydrodistillation. ld50 was calculated...

Ibuprofen is one of the most important non-steroidal anti-inflammatory drugs used in the treatment of inflammatory diseases. In its pure state, ibuprofen presents poor physical and mechanical characteristics and its use in solid dosage forms needs the addition of excipients that improve these properties. The selection of the best excipients and the most suitable pharmaceutical dosage form to ca...

Dynamic viscosities of a number of vegetable oils (castor oil, palm oil, sunflower oil and coconut oil) and lubricant oils (2T and 4T) have been determined at temperature range 30 90C using Ubbelohde viscometer. An associative neural network is used to compute the viscosities of oils for unknown temperatures after training the neural network with type of oil, temperature as input and viscosity ...

Ricin is a protein toxin found only in mature castor (Ricinus communis L., Euphorbiaceae) seed that enzymatically destroys the ribosomes of eukaryotes. The presence of ricin in the high protein meal of castor has historically reduced its value as an animal feed. Since ricin has the potential to be used as a chemical warfare and bioterrorism agent, the production and processing of castor has und...

Bio-aviation fuel was firstly synthesized by hydroprocessing castor oil in a continuous-flow fixed-bed microreactor with the main objective to obtain the high yield of aviation fuel and determine the elemental compositions of the product phases as well as the reaction mechanism. Highest aviation range alkane yields (91.6 wt%) were achieved with high isomer/n-alkane ratio (i/n) 4.4-7.2 over Ni s...
