Abstract: In this study, a new source of ellagic acid (EA) is reported. Euphorbia antisyphilitica or “candelilla” was used to extract phenolic dilactone. Cereous layers and fibrous tissue were analyzed. A completely randomized
experimental design with a treatment factorial arrangement was employed. The factors considered were: plant/extracting agent
ratio, extraction temperature and time. Candelilla wax does not contain EA. Temperature and the ratio plant/extracting agent
were determinant during the EA extraction process. Around 20 mg of free EA per gram of fibrous tissue were found. Residues
of candelilla are a good source of EA.
Keywords: Euphorbia antisyphilitica Zucc - candelilla - extraction - ellagic acid
