Abstract: A water-soluble pectic polysaccharide was isolated from the aqueous extract of the seeds of Lagenaria siceraria. is composed of methyl-α-D-methyl galacturonate, α-D-galactose and β-D-galactose in a ratio of nearly 1:1:1.Compositional analysis, methylation analysis, periodate oxidation study and NMR studies (1H, 13C, DQF-COSY, TOCSY, NOESY, ROESY, HMQC, and HMBC) revealed the presence of the following repeating unit in the polysaccharide: →4)-β-D-Galp-(1→4)-α-D-GalpA6Me-(1→2)-α-D-Galp-(1→ This polysaccharide showed splenocyte, thymocyte as well as macrophage activations. Moreover, it exhibited antioxidant activities
