Abstract

This work describes the chemical and micro-structural characterization of candelilla (Euphorbia antisyphilitica Zucc) plant which produces a natural edible wax. Chemical composition analysis included total fat, protein, crude fiber, dry material, moisture, ashes, total of reducing sugars, hydrolysable and condensed polyphenols contents. Micro-structural characterization was made using Environmental scanning electron microscope (ESEM). Results demonstrated that contains a high level of lipids (15.9%), crude fiber (9%) and is a source of ellagic acid (2.2 µg/g). Candelilla wax is deposited in the external side of the stems surrounding fibers thus forming resistant structure. This is important for the development of novel methods for extraction, use and potential applications.

Key words: Euphorbia antisyphilitica Zucc, microscopy, condensed and total polyphenols, candelilla wax.
