Ricinus communis, the castor bean [1] or castor oil plant, [2] is a species of perennial flowering plant in the spurge family, Euphorbiaceae. It is the sole species in the monotypic genus, Ricinus, and subtribe, Ricininae. The evolution of castor and its relation to other species are currently being studied using modern genetic tools. [3]
Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant Ricinus communis. [1] The seeds are 40 to 60 percent oil. [2] It is a colourless or pale yellow liquid with a distinct taste and odor. Its boiling point is 313 °C (595 °F) and its density is 0.961 g/cm 3. [3]
Ricin (/ ˈ r aɪ s ɪ n / RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis. The median lethal dose (LD 50) of ricin for mice is around 22 micrograms per kilogram of body weight via intraperitoneal injection. Oral exposure to ricin is far less toxic.
The seeds of the castor oil plant Ricinus communis contain the highly toxic carbohydrate-binding protein ricin. [5] A milky latex is a characteristic of the subfamilies Euphorbioideae and Crotonoideae, and the latex of the rubber tree Hevea brasiliensis is the primary source of natural rubber.

Ricinus communis Toxalbumins are toxic plant proteins that disable ribosomes and thereby inhibit protein synthesis , producing severe cytotoxic effects in multiple organ systems. They are dimers held together by a disulfide bond and comprise a lectin (carbohydrate-binding protein) part which binds to the cell membrane and enables the toxin part ...
Caruncle Carunculate seeds of Ricinus communis (Castor beans) The particular elaiosome in the spurge family Euphorbiaceae is called caruncle (Latin caruncula "wart"). Seeds that have caruncles are carunculate; seeds that do not have caruncles are ecarunculate.
The silk is produced by worms that consume the leaves of the castor oil plant (Ricinus communis). [3] Generally, silk cocoons are boiled with the worm inside to preserve the continuity of the fibers. Whereas Eri silk cocoons are open at one end, allowing the moth to leave before the cocoon is processed.
