Ricinus communis

These alkaloids include the substituted pyridone ricinine [524-40-3] (53), CgHgN202, which is easily isolated in high yield as the only alkaloid from the castor bean (Ricinus communis L.). The castor bean is also the source of castor oil (qv), which is obtained by pressing the castor bean and, rich in fatty acids, has served as a gentie cathartic. 

Ricin (toxin from Castor bean Ricinus communis) [A chain 96638-28-7 B chain 96638-29-8] Mr -60,000, amorphous. Crude ricin, obtained by aqueous extraction and (NH4)2S04 pptn, was chromatographed on a galactosyl-Sepharose column with sequential elution of pure ricin. The second peak was due to ricin agglutinin. [Simmons and Russell Anal Biochem 146 206 1985.) Inhibitor of protein synthesis. EXTREMELY DANGEROUS, USE EXTREME CARE [instructions accompany product].

Delayed-action cytotoxin that inhibits protein synthesis (ribosomal inactivating protein) that is obtained from castor beans (Ricinus communis). Waste from production of castor oil contains about 5% ricin by weight. It is a white powder that is soluble in water and relatively heat stable. Aqueous solutions are resistant to chlorine at 10 ppm. It is persistent in the environment. 

There is still some discordance about markers for ATI cells [17, 18]. Varieties of glycocalyx appear to be expressed in ATI versus ATII cells, which can be distinguished by the binding of specific lectins. Lycopersicon esculen-tum lectin, for example, appears to adhere specifically to the apical plasma membrane of ATI cells [19, 20], Other lectin markers that have been reported in AEC typing are Ricinus communis agglutinin, Erythrina cristagalli lectin, soybean lectin and Bauhinia purpurea agglutinin (all for the ATI phenotype),... 

Castor oil is derived from the castor plant Ricinus communis). The castor plant has a long and rich history of uses in human society. The oil from the plant is non-digestible, and is commonly known to be a medicinal purgative. The castor bean contains the protein ricin, a substance that is famously toxic in humans [50]. The lack of food value from the castor plant coupled with the issues of toxicity inherent in extraction of ricin has mostly limited the use of castor oil to the industrial sector.

Ricin toxin— Ricinus communis (castor beans)... 

Ricin is a potent cellular protein toxin contained in the beans of the castor been plant (Ricinus communis), which is extensively cultivated for oil production and is also a common ornamental garden plant. Ricin is able to inhibit ribosomal protein synthesis eventually causing cell death, and owing to these properties it has been allegedly used in terrorist and criminal activities. After trypsin digestion of castor bean crude extracts, Ostin et al. [105] were able to unambiguously...
