In the present study, the exopolysaccharide (EPS) producing strain HY was isolated from home-made Sichuan Pickle and identified as Lactobacillus plantarum. The EPS was purified by ethanol precipitation, and fractionation by column chromatog., and the yield of purified HY EPS was 1.423 g/L. The mol. weight of the purified HY EPS was 9.549 × 104 Da and composed of mannose, galactose, glucuronic acid and glucose in a mass percentage of 72.99%, 17.27%, 6.99% and 2.75%, resp. FT-IR spectrum exhibited the existence of carboxyl and hydroxyl group. Partial sugar residues and glycosidic bond present in HY EPS could be identified by NMR spectroscopy, i.e. α-D-glucose and α-D-mannose residues. The degradation temperature (320 °C) and m.p. (122.78 °C) of the HY EPS were determined by thermogravimetric anal. (TGA) and differential scanning calorimeter anal. (DSC). A highly porous structure of EPS was observed by SEM, and the AFM anal. of the EPS revealed presence of spherical lumps. Meanwhile, the in vitro biol. activity assays of HY EPS showed considerable antioxidant and α-amylase inhibitory activities, suggesting its promising potential to be applied in the food and pharmaceuticals industry.
