Extraction, Structural Characteristics, and Antioxidant Activity of a Glucose-Dominated Polysaccharide, NJPW, Purified from (D.Don) DC. .

ABSTRACT: With the hypothesis that polysaccharides (NJPs) could be the functional constituent contributing to the pharmacological effects of , this study comprehensively examined the extraction approach, chemical characteristics, and antioxidant activities of the polysaccharide from . An ultrasonic-assisted extraction method was developed, with the critical optimum parameters determined as follows: ultrasonic temperature at 64 °C, solid-liquid ratio of 1:45, and ultrasonic time of 52 min. Through purification, a pure polysaccharide (NJPW) was obtained, and its structure was characterized. The monosaccharides of NJPW mainly included glucose, arabinose, and galactose, with a molar weight of 21.907 kDa. NJPW exhibited irregular sheet-like structures, demonstrating the characteristic FTIR and NMR spectr
