“…The IC 50 of PUE, PMAE and PHRE were 1.48, 1.81 and 1.98 mg/mL. Compared with EDTA, chains as well as breaking intermolecular hydrogen bonds (Tao and Xu, 2008). The present study confirmed the results that PMAE, which was degraded during microwave heating processing, showed higher antioxidant activities than polysaccharides extracted by conventional methods.…”

Microwave-assisted extraction (MAE) technique was employed for the extraction of himematsutake (Agaricus blazei Murrill) polysaccharide (PMAE) and optimized by Box-Behnken design. The optimum conditions were extraction time 29.37 min, microwave power 400 W, extraction temperature 74.64℃ and ratio of water to material 32.7:1 with an enhanced yield of 12.35%. Furthermore, PMAE had increased antioxidant activity in various oxidative systems in vitro when compared to polysaccharides extracted by conventional methods. The data obtained clearly showed that MAE is a fine way to extract the polysaccharides in A. blazei Murrill. Further, PMAE may be developed into a functional food as well as potential therapeutic agent.

“…A typical method includes the use of solvent such as alkali or LiCl/Me 2 SO to break the intermolecular hydrogen bonds of the polysaccharides, resulting in dissolution. However, such solvent systems are not applicable for bioactivity assays [12]. Apart from that, various chemical modiications have been developed to enhance the solubility of polysaccharides (Figure 2).…”

Carbohydrates can be found in many natural sources, and they play a central role in various biological processes. These versatile biopolymers are diicult to dissolve in solutions, and therefore converting them into functional forms is a signiicant challenge, whereby both experimental and computational studies become critical. This chapter discusses commonly used experimental approaches to increase solubility of carbohydrates in solutions and computational studies to rationalize their conformations and solvation efects. Advances of experimental and computational methods for the study of carbohydrates will guide the design approaches to use carbohydrates in industrially and academically relevant applications.

“…For example, the high power of microwave extraction can cause selective migration of the target compounds from the material to the surroundings at a more rapid rate. Tao and Xu reported that degradation occurred in the structure of polysaccharides during the microwave heating process [28]. Marshall et al also studied the possibility of minimizing the disassembly of polysaccharides during microwave extraction [29].…”

In this study, three extraction methods of polysaccharides in Purslane were compared and analyzed, and the best method was ascertained. Purslane polysaccharides were extracted using water, ultrasonic and microwave. By the results of single factor experiments and orthogonal experiments, the optimal extracting conditions were selected and then the best extraction method was determined. In order to calculate the extraction yield of polysaccharides, its content were measured by the phenol-sulfuric acid method using glucose as the standard, and then the efficiency of three extraction methods was evaluated. The results showed that the extraction yield of ultrasonic was 35.42% under the optimal conditions of 60°C, 60 min, 1:20 and 200w. The extraction yield of microwave method was 32.12% under the optimal conditions of 3 min, 1:25 and 500w. The extraction yield of water method was 31.22% under the optimal conditions of 80°C, 2 h, 1:30 and 3 times. It could be concluded that ultrasonic method was the best one in these three methods.
