Castor oil is glycerol triester of 12-hydroxyoleic acid (ricinoleic acid) (Falbe, J.
Castor oil is characterized by high levels of ricinoleic acid (about 900 g [kg.sup.-1]) and low levels of other fatty acids (about 30 g [kg.sup.-1] oleic, 40 g [kg.sup.-1] linoleic, and 30 g [kg.sup.-1] saturated fatty acids; Brigham, 1993).
All three acids--lesquerolic, densipolic, and auricolic--are similar to ricinoleic acid, the main fatty acid in castor oil.
Ethanol showed a better performance in the extraction, due to the fact that the major component of castor oil is ricinoleic acid, which has a hydroxyl at its carbon 12, which increases its solubility in alcohols (GUSTONE, 2004).
