Abstract

In this work the mucilage obtained from the cladodes of a not previously investigated accession of Opuntia stricta (Haw.) Haw. (syn. Opuntia dillenii (Ker-Gawl) Haw), collected in Sicily, was analysed by C-13-NMR. The yield of mucilage extracted from cladodes in aqueous medium was 2.55%. The monosaccharides identified, after acidic hydrolyses of the mucilage, were arabinose (36.48%), galactose (32.31%), xylose (15.33%), glucose (10.45%) and rhamnose (5.40%). The mucilage showed a sufficient antimicrobial activity and excellent antioxidant property.
