A novel neutral polysaccharide designated as PAP1b was isolated from  Areca catechu  L. by hot water extraction, ethanol precipitation, and column chromatography. PAP1b was mainly composed of mannose, galactose, xylose, and arabinose in a ratio of 4.1:3.3:0.9:1.7, with an average molecular weight of 37.3 kDa. Structural characterization indicated that the backbone of PAP1b appeared to be composed mainly of → 6-β-Man p -(1 →, → 4)-α-Gal p -(1 → and → 3,6)-β-Man p -(1 →) residues with some branches, and terminal of (1 →)-linked-β-Man p  residues. The results of bioactivity experiments showed that PAP1b had antioxidant  in vitro , esspecially on scavenging DPPH and hydroxyl radicals. Therefore, the polysaccharide from  Areca catechu  L. could be used as a potential antioxidant in functional food.
