The present invention relates to a method for preparing ricinoleic acid ester from a pure or mixed vegetable oil, in particular castor oil, wherein the method includes at least the step of enzymatic transesterification in the presence of a light alcohol and using a typo-selective lipase in order to obtain a fraction enriched with ricinoleic acid ester. The method according to the invention for producing ricinoleic acid ester includes the steps: i) a first transesterification reaction in the presence of a light alcohol and a lipase extracted from Geotrichum candidum, in order to obtain a mixture M containing AR mono-, di- and triglycerides, fatty acid esters other than AR, alcohol; ii) the step of separating said mixture M into at least two fractions, including a fraction A enriched with AR glycerides, and a fraction B enriched with fatty acid esters other than RA; iii) the step of converting said AR glycerides into AR esters consisting of a fraction C rich in AR esters and a fraction rich in alcohols.
