“…The optimal extraction conditions for Pomelo Peel's polysaccharide were as follows: solid to liquid ratio of 34 mL/g, extraction duration of 2 h, two extraction cycles, temperature of 87 ℃, yielded a polysaccharide extraction rate of 8.73% (Juan et al 2019).The optimum extraction conditions for Erythronium sibiricum bulb polysaccharides were a solid to liquid ratio of 37 mL/g, extraction duration of 4.28 h, temperature of 90 °C, three extraction cycles. This resulted in a polysaccharide extraction rate of 37.25% ± 0.17% (Chen et al 2016a).…”

Background Over time, the amount of germs resistant to antibacterial medications has been steadily rising because of their prolonged and indiscriminate use. The increase in drug resistance significantly threatens to human health and has become a globally recognized issue of concern. Therefore, identifying new antibacterial drugs is urgently needed. Forward Polysaccharides are natural macromolecular substances that exist in plants, microorganisms, and animals, They have an immense amount of use in the food and medical industries. Polysaccharides can be categorized as plant, animal, or microbial based on the sources of the polysaccharides. Conclusion Polysaccharides are natural compounds with antibacterial properties that exerts antibacterial activity by disrupting bacterial cell walls and cell membranes. They show potential as candidates for the creation and application of novel antibiotics. This article reviews the classification of polysaccharides, their isolation and purification, mechanisms of action, and antibacterial activity. The primary objective of this study is to lay down an empirical groundwork for examining the antibacterial properties of polysaccharides.

“…Polysaccharides are the important biological macromolecules necessary for organism. Polysaccharides have a variety of therapeutic effects, including anti-inflammatory (Chen et al, 2016;Zhang et al, 2020), antioxidant (Chen, Huang, et al, 2019;Cheng et al 2020;Chen & Huang, 2018;Liu et al, 2018;Mei et al, 2020;Zhou, et al, 2021;Mu, et al, 2021;, anti-tumor Benchamas, et al, 2021), anti-diabetes (Gao et al, 2015), and neuroprotective activities (Ho et al, 2010). Some polysaccharides have been developed as drugs for the treatment of diseases and health food because of their many effects.…”

Extraction and deproteinization process of polysaccharide from purple sweet potato (PPSP) were optimized via the response surface methodology (RSM). The results indicated that the optimal conditions of extraction in hot water of PPSP were as follows: The extraction temperature was 120℃, the extraction time was 2.5 hr, and the solid-liquid ratio was 1∶10 (g/ml). The optimal conditions of Sevage deproteinization were as under the oscillation time was 20 min, the deproteinization times was twice, and polysaccharide solution-Sevage reagent ratio was 1:1 (ml/ml). The extraction yield of PPSP was 3.32%, and the protein removal rate was 93.14% in such a condition.

“…The current commonly used extraction methods have the disadvantage of producing a low extraction yield, although there have been studies on the optimization of the extraction technology for ODP [9,10]. The hot water extraction technology is still the classic and the main extraction method used to obtain the polysaccharides due to its convenience, low cost, and high activity [11,12,13]. At present, no information is available regarding the comparison of extraction yield and the antioxidant activities of ODP from different growth stages of the plant.…”

Abstract:Use of natural polysaccharides in medicine and food has wide interest in research. In this study, we extracted and purified some polysaccharides from cactus Opuntia dillenii Haw. (ODP). Some preliminary functions of these products were characterized. Under the optimal purification conditions, the yield of ODP extracted from the 2-4 month-old Opuntia dillenii Haw. (T-ODP) was 30.60% ± 0.40%, higher than that of ODP from the 5-10 month-old materials (O-ODP) (18.97% ± 0.58%). The extracted ODP was purified by DEAE sepharose fast flow anion exchange and Sephacryl S-400 chromatography with four fractions obtained (ODP-Ia, ODP-Ib, ODP-IIa and ODP-IIb). Analysis with UV-vis chromatography indicated that ODP-Ia and ODP-IIa were relatively homogeneous molecules with a molecular weight of 339 kD and 943 kD, respectively. Results of infrared spectroscopy indicated that ODP, ODP-Ia, and ODP-IIa were acidic polysaccharides. Further, the antioxidant activity against DPPH (1,1-diphenyl-2-picrylhydrazyl) radical, hydroxyl radicals, and superoxide radical in vitro demonstrated that the T-ODP exhibited higher antioxidant activity than the O-ODP, and the purified fraction (ODP-Ia) was superior to the ODP. These results will offer a theoretical basis for further research on the structure-function relationship of ODP and the rational utilization of Opuntia dillenii Haw.
