| Abstract Crude polysaccharides of Lentinus edodes were extracted using homogenate method. Factors affecting the yield of crude polysaccharides were investigated and optimized by response surface methodology. The homogenate extraction method was compared with traditional heating extraction method. The antioxidant activity of crude polysaccharides from Lentinus edodes was evaluated. Results showed that, the optimal conditions of homogenate extraction were as follows: solvent pH, 10; liquid-solid ratio, 30: 1 (mL: g), extraction time, 66 s; number of extraction, 1. Under these conditions, the yield of crude polysaccharides was (13.2 ± 0.9)%, which was 29.82% higher than that of traditional heating extraction. Crude polysaccharides of Lentinus edodes had good... |

| Abstract The goals of this exploration were to find out the optimum conditions of ultrasound assisted extraction (UAE) of L. Barbarum crude polysaccharides. Furthermore, to research the impacts of three multi-frequency ultrasound assisted extraction modes on the yield of L. Barbarum crude polysaccharides. The results showed that by applying the traditional single-frequency UAE mode, the optimum extraction time was 30 min, extraction temperature of 60 °C, and solid/liquid ratio of 20 g/600 mL, at a power density of 300 W/L, and ultrasound frequency of 28 kHz. Secondly; a comparison was carried out between three UAE modes using the optimum extraction conditions obtained previously. The energy aggregation counter flow dual-frequency UAE mode gave the highest... |
