Abstract
A water-soluble polysaccharide (DNP), isolated from the aqueous extracts of the stem of Dendrobium nobile Lindl., was found to have an average molecular weight (Mw) of about 8.76 × 104 Da. Monosaccharides analysis revealed that DNP was composed of rhamnose, arabinose, xylose, mannose, glucose and galactose in a molar ratio of 1.00:2.80:2.20:30.76:117.96:31.76. The evaluation of antioxidant activity in vitro revealed that DNP is a novel potential antioxidant. The NMR spectra suggested that the main structure of DNP was possible as
