This study aimed to compare the effects of four solvent extractions on the physicochem. properties, antioxidant and hypoglycemic activities of polysaccharides from Mentha haplocalyx (MHPs). The solvent extractions included hot water, citric acid (pH 3.0), 5% NaOH/0.05% NaBH4 and 0.9% NaCl. Four corresponding MHPs named as MHP-W, MHP-C, MHP-A and MHP-S were obtained, resp. The exptl. results showed that the extraction yields, basic chem. components, monosaccharide contents, mol. weights, antioxidant and hypoglycemic activities of four MHPs were significantly different. However, their thermal stabilities, preliminary structural characteristics and monosaccharide types were similar. MHP-A possessed the highest extraction yield of 9.37 ± 0.24% and the smallest mol. weight MHP-W had the highest uronic acid content and the largest mol. weight More specifically, MHP-C exhibited the highest sugar content, the most remarkable antioxidant abilities of DPPH radical scavenging activity and ferric reducing power, and the strongest inhibitory activities on α-glucosidase and α-amylase. The above results indicated that MHP-C extracted with citric acid could be served as a promising bioactive substance for applications in the functional food and medicine industries.
