Abstract
The effects of ultrasonic treatment on the physicochemical properties and antioxidant activities of the polysaccharide from Cyclocarya paliurus leaves were investigated. The physicochemical properties were detected by high-performance gel permeation chromatography (HPGPC), high-performance anion exchange chromatography coupled with pulsed amperometric detection (HPAEC-PAD) and fourier transform infrared spectrometer (FT-IR) as well. The antioxidant activities were evaluated by the assay of DPPH, hydroxyl free radical, β-carotene-linoleic acid, respectfully. Results showed that no considerable change was observed on the structure between the polysaccharide of Cyclocarya paliurus (CP) and the ultrasonic polysaccharide of Cyclocarya paliurus (UCP) by FT-IR, and no apparent differences were found on the content of sugar, uronic acid and protein after the ultrasonic treatment, but difference appeared in the ratio of monosaccharide composition of CP (1.0:4.6:3.5:4.5) and UCP (1.0:5.9:3.9:4.4), and the antioxidant activities of CP were promoted after ultrasonic treatment.Entities:
