Description
Summary:•Noni-PLS is composed by homogalacturonan and rhamnogalacturonan.•Noni-PLS reduced inflammatory process.•Noni-PLS also reduced the MPO and GSH levels. Polysaccharides extracted from plants are very promising molecules in the field of pharmacotherapy. Knowing this, the aim of this study was to extract, characterize and evaluate the action of the polysaccharide of Morinda citrifolia Linn (Noni-PLS) in biological models of inflammatory processes. The characterization tests shown that sample refers to a heteropolysaccharide composed mainly of homogalacturonan and rhamnogalacturonan. This polysaccharide at dose of 10 mg/kg, when tested in our models of inflammation, showed significant activity in reducing carrageenan-induced paw oedema as well as all mediators edemas. This polysaccharide was able to inhibit the migration of leukocytes to the site of inflammation, and still reduced inflammatory nociception tests. This results, allows us to conclude that the polysaccharide extracted from Morinda citrifolia linn has anti-inflammatory potential since it reversed inflammatory parameters such as edema, leukocyte migration and nociception.
