Min, Wei-Hong published the artcileCharacterization and antioxidant activity of an acidic exopolysaccharide from Lactobacillus plantarum JLAU103, HPLC of Formula: 59-23-4, the main research area is Lactobacillus exopolysaccharide antioxidant oxygen radical absorbance capacity; Antioxidant activity; Exopolysaccharide; Lactobacillus plantarum; Oxygen radical absorbance capacity; Purification.
An acidic exopolysaccharide (EPS) designated as EPS103 was isolated, purified and characterized from Lactobacillus plantarum JLAU103. EPS103 had a relatively lower mol. weight of 12.4 KDa and was consisted of arabinose, rhamnose, fucose, xylose, mannose, fructose, galactose, and glucose in an approx. molar ratio of 4.05: 6.04: 6.29: 5.22: 1.47: 5.21: 2.24: 1.83. A specific spectrogram of acidic polysaccharide was obtained by FT-IR anal., and both α- and β-type configurations were presented in EPS103 based on the NMR spectroscopy. Microstructural anal. of EPS103 demonstrated a smooth and glittering cube structure, and presence of many homogeneous rod-shaped lumps. Comprehensive study of in vitro antioxidant activity indicated that EPS103 possess strong scavenging abilities against hydroxyl, ABTS, and DPPH radicals with the maximum of 80.4%, 65.5%, and 60.5%, resp., at 10 mg/mL concentration Furthermore, EPS103 also showed strong ferrous ions chelating activity and oxygen radical absorbance capacity. These results together indicated that the EPS103 isolated from L. plantarum JLAU103 has great potential for use as a natural antioxidant or functional additive in foods industry.
