Dragon fruit is a tropical fruit with good taste. It can bring health benefits to human body. As one of the major bioactive components in this fruit, the polysaccharides might contribute to the health benefits. However, the precise structure information remains unknown. A leading polysaccharide of dragon fruit pulp, DFPP, was purified and identified by NMR and GC-MS. â4-ß-d-GlcpA-1â, â6-ß-d-Galp-1â and â4-α-l-Rhap-1â constituted the backbone and α-l-Araf-1â5-α-l-Araf-1â formed the branch chain. The precise structure was putatively identified as below. The molecular weight was 2.2×10(3)kDa. The structure information of polysaccharides will be helpful to understand this fruit.
