Pectin-like polysaccharide extracted from leaves promotes antioxidant, immunomodulatory and emulsifiers applied in therapeutic formulations.

The objective of this work was to isolate a polysaccharide similar to pectin from leaves, not yet reported in the literature, and to evaluate its antioxidant, cytotoxic and immunomodulatory profile. Pectin was extracted from the leaves in three stages, organic solvent followed by acidified water and ethanol precipitation. With the pectin obtained, the physicochemical characterization of the molecule was carried out using high-performance liquid chromatography, Fourier-transform infrared spectroscopy, nuclear magnetic resonance (C and H) and different thermal and elemental analysis.
