•The extractability of crude Zizyphus jujuba cv. Junzao polysaccharides was significantly enhanced by the ultrasound treatment.•CZPU contained more glucose than CZPH.•CZPU showed stronger antioxidant activities compared with CZPH.
Crude Zizyphus Jujuba cv. Junzao polysaccharides (CZP) were extracted by hot water and ultrasound-assisted extraction respectively. Using a short application of ultrasound, the yield of polysaccharides increased from 6.23 to 7.95%, which represents an increase of about 27.6%. Both CZPU and CZPH were composed of arabinose, rhamnose, glucose, galactose, and mannose. However, the molar ratio of CZPU was 5.46: 4.96: 5.17: 2.63: 1, while it was 5.46: 4.89: 3.65: 2.54: 1 for CZPH. Furthermore, CZPU had stronger antioxidant activities than CZPH by evaluating in hydroxyl radical and ferric-reducing antioxidant power (FRAP) assay.
