“…15 However, the curve decreased aer the peak, and the reason for this could be that a higher temperature and too much time can damage the structure of crude polysaccharides due to the ultrasonic power. 16 According to the above results, extraction powers of 200-250 W, extraction times of 50-70 min, extraction temperatures of 50-70 C, and ratios of water to material from 40 : 1 to 60 : 1 were selected for the subsequent experiments.…”

“…Figure 3(A) showed the effect of changing rotation speed on the apparent viscosity of CCPP. The apparent viscosity decreased with increasing rotation speed (shear-thinning) at the same concentration (3mg/mL) and temperature (25 o C), a behaviour that was characteristic of Pseudoplastic fluids [16]. The effect of solute concentration on the viscosity of CCPP was measured at 1.5 r/min rotation speed and the temperature was fixed at 25 o C. As shown in Figure 3(B), the apparent viscosity of CCPP increased as the solute concentration increased.…”

The extraction condition of crude polysaccharides from Codonopsis pilosula by hot water reflux method was studied and the results analyzed by kinetic model. Then, the extraction rate and maximum extraction temperature were determined. furthermore, the thermal and pH stability and the rheological properties of the crude polysaccharide were also studied. crude Codonopsis pilosula polysaccharide (CCPP) under different conditions was extracted by hot water reflux method, the content was determined by phenol-sulfuric acid and DNS method, and the kinetic model of the extraction process was established. The viscosity was determined under different solute concentration, salt concentration, rotation speed, pH, and temperature. The thermal stability and pH stability were determined; the protein content and sulfate ion content were determined by the coomassie brilliant blue method and barium sulfate turbidimetry method, respectively. The yield of CCPP by the hot water reflux method was 25.72%. At 50 oC, the maximum extraction concentration, the rate constant and the linear relationship between the rate constant and the time were obtained at different ratios of material to liquid. The extraction process of this experiment coincided with Fick`s second law, R2 was greater than 0.88 and with the increase of extraction time, the dissolution rate increased, but with the increase of the ratio of material to liquid, the dissolution rate was decreased. CCPP showed a loss of polysaccharide fluidity as temperature increased and was affected by pH change. The apparent viscosity was affected by a change in solute concentration, temperature, pH, rotation speed and salt and sucrose concentrations.

“…In general, different extraction methods significantly influence the yields, physicochemical characteristics, and bioactivities of polysaccharides extracted from natural resources [20,21,22]. To extract the polysaccharides from plants, the traditional hot water extraction (HWE) is commonly used.…”

In order to explore Cassia seed polysaccharides (CSPs) as natural antioxidants for application in the functional-food industry, microwave-assisted extraction (MAE) was optimized for the extraction of CSPs by using a response surface methodology. Furthermore, the chemical structures and antioxidant activities of CSPs extracted by MAE and hot water extraction were investigated and compared. The maximum extraction yield of CSPs extracted by MAE (8.02 ± 0.19%) was obtained at the optimized extraction parameters as follows: microwave power (415 W), extraction time (7.0 min), and ratio of water to raw material (51 mL/g). Additionally, the contents of the uronic acids, molecular weight, ratio of constituent monosaccharides, intrinsic viscosities, and degrees of esterification of CSPs were significantly affected by the MAE method. Moreover, CSPs exhibited remarkable 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) ABTS, 2,2-diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl DPPH, nitric oxide, and hydroxyl radical scavenging activities as well as reducing power. The high antioxidant activities observed in CSPs extracted by MAE could be partially attributed to its low molecular weights and high content of unmethylated galacturonic acid. Results indicate that the MAE method could be an efficient technique for the extraction of CSPs with high antioxidant activity, and CSPs could be further explored as functional food ingredients.
