DefinitionThis section has been translated automatically.
Hydroxy fatty acid (molecular formula C18H34O3), which is esterified as triglyceride(triricinolein), is an efficacy determining main component of castor oil .
It is obtained by hydrolysis of the castor oil.
The triglyceride of ricinoleic acid (triricinolein) is cleaved in the gut by lipases. By stimulating the prostaglandin E3 synthesis and inhibiting the adeninucleotide transferase, the ricinoleic acid released in this way stimulates the intestinal motor function, increases the secretion of water and electrolytes and is thus mainly responsible for the laxative effect of castor oil.
