Polysaccharide composition of the fruit juice of Morinda citrifolia (Noni)

Chemical characterisation of the ethanol insoluble fraction of Noni juice (Noni-ppt) shows that it contains predominantly pectic polysaccharides (homogalacturonan, rhamnogalacturonan, arabinan, and type I arabinogalactan), in addition to arabinogalactan-protein and low amounts of xyloglucan, heteroxylan and heteromannan.
