“…To the best of our knowledge, the extraction parameters, including microwave power, liquid-to-solid ratio, extraction time, and extraction temperature are important, since they can affect the extraction rate of polysaccharides [10]. Figure 1a shows that the extraction yield significantly increased the microwave power from 400 W to 550 W, which reached a maximum yield at 550 W. However, the extraction yield was ultimately decreased with the increase of microwave power after 550 W, which might be due to the glycosidic linkage of MPPG being damaged by the higher microwave power, and subsequently leading to the degradation of the polysaccharides [20].…”

“…Figure 1a shows that the extraction yield significantly increased the microwave power from 400 W to 550 W, which reached a maximum yield at 550 W. However, the extraction yield was ultimately decreased with the increase of microwave power after 550 W, which might be due to the glycosidic linkage of MPPG being damaged by the higher microwave power, and subsequently leading to the degradation of the polysaccharides [20]. Moreover, the enhanced microwave power will decrease the antioxidant activity of the polysaccharides, which is mostly due to the biological activity of polysaccharides being decreased due to the rising temperature [10]. Therefore, 550 W was considered to be the optimal microwave power in this experiment.…”

“…Compared with these extraction methods, microwave-assisted extraction can enhance the extraction rate more efficiently through facilitating the release of intracellular substances and extract the nature-based bioactive constituents, such as polysaccharides that are present in the cell walls [7]. It is also more environmental friendly due to the reduced consumption of solvents and energy [8,9,10]. However, many research studies have indicated that extraction methods can significantly affect the yield of polysaccharides, as well as their physicochemical properties and biological activities [11,12]; that is to say, the effects on the extraction yield, structural characteristics, and biological characteristics of the polysaccharides prepared by different methods should not be neglected.…”

Microwave-Assisted Extraction, Purification, Partial Characterization, and Bioactivity of Polysaccharides from Panax ginseng

Polysaccharides are a main active substance in Panax ginseng; however, microwave-assisted extraction used to prepare P. ginseng polysaccharides (MPPG) has rarely been reported, and knowledge of the bactericidal activity of P. ginseng polysaccharides remains low. Thus, this study was designed to investigate the extraction of P. ginseng polysaccharides by using two methods—hot water extraction and microwave-assisted extraction—and compare their chemical composition and structure. In addition, their antibacterial and antioxidant activities were also determined. The data implied that P. ginseng polysaccharides extracted by microwave-assisted extraction possessed a higher extraction yield than hot water extraction (WPPG) under optimized conditions, and the actual yields were 41.6% ± 0.09% and 28.5% ± 1.62%, respectively. Moreover, the preliminary characterization of polysaccharides was identified after purification. The WPPG with the molecular weight (Mw) of 2.07 × 105 Da was composed of Man, Rib, Rha, GalA, Glu, Gal, and Arab, and the typical characteristics of polysaccharides were determined by IR spectra. Compared with WPPG, MPPG had a higher Mw, uronic acid content, and Glu content. More importantly, the antioxidant activity of MPPG was higher than WPPG, which was probably ascribed to its highly Mw and abundant uronic acid content. Besides, both of them exhibited high bactericidal activity. These results demonstrate that microwave-assisted extraction is an effective method for obtaining P. ginseng polysaccharides, and MPPG could be applied as an antioxidant and antibacterial agent.

“…Edible fruits also contain large amount of antioxidants in combination with vitamins (mainly vitamin C) and polyphenols. Some of the most active ones are papaya ( Carica papaya ), guava ( Psidium guajava (Lim et al., 2007)), sea-buckthorn ( Hippophae rhamnoides (Wei et al., 2019)), fig ( Ficus carica ), persimmon ( Diospyros kaki (Katsube et al., 2004)) and various berries (Hakkinen et al., 1999).…”

Radical scavenging activity of extracts obtained from 16 plants harvested in South Hungary was assessed and compared to the activity of ascorbic acid standard. During extraction, a novel technique involving an ethanolic treatment at ambient temperature was used for advanced active component release. Although the procedure is time consuming, it serves as an efficient and harmless route to extract valuable antioxidant compounds from their natural sources. The as-prepared extracts consist of two phases (except Allium sativum), a clear solution and a thick suspension containing solid plant parts that separates in about 2 h. The samples were analysed by the antioxidant assay based on the scavenging of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals. For most of the species, the solid phase retained considerable amount of available antioxidant agents, while the solution parts showed significant radical scavenging activity. The main exceptions were Nigella sativa, Hippophae rhamnoides and Linum usitatissimum, where the solid parts were less active. Overall, the extracts possessed remarkable antioxidant activity that were compared to published literature data and were found to be superior.

“…Furthermore, Hajji et al, (2019) isolated a novel water-soluble polysaccharide (PLP1) from the root barks of Periploca laevigata by hot water extraction and further purification by diethylaminoethyl cellulose (DEAE)-sepharose chromatography, and this compound exhibited a strong antioxidant activity. Recently, Wei et al, (2019) isolated polysaccharides from seabuckthorn berries (PSB) and investigated the role of microwave power on their antioxidant activities. Furthermore, a water-soluble polysaccharide (MWP) with a galactose-, glucose-, mannose-, fructose with 1:33.2:8.4:7.2 was successfully isolated from Malus micromalus Makino fruit (Hui, Jun, & Chuang, 2019) and this polysaccharide showed degrees of scavenging effects on hydroxyl, DPPH (2,2-ddiphenyl-2-picrylhydrazyl), and superoxide radicals in a dose dependent manner.…”

Polysaccharides are naturally occurring biomacromolecules composed of carbohydrate molecules linked by glycosidic bonds. A number of polysaccharides are known to possess beneficial therapeutic effects against inflammation, diabetes, cardiovascular diseases, and cancers. Indeed, polysaccharides are reportedly effective free radical scavengers and antioxidants, thereby playing a critical role in the prevention of damage to living organisms under oxidative stress. In this review we provide an overview of the sources, extraction, and antioxidant activities of some natural polysaccharides.
