TL;DR: This review provides a comprehensive summary of the most recent developments in physiochemical, structural features and biological activities of bioactive polysaccharides from a number of important medicinal plants, such as poly Saccharide from Astragalus membranaceus, Dendrobium plants, and Dimocarpus longan Lour.

TL;DR: In this paper, the physicochemical characterizations and antioxidant properties of these sulfated polysaccharide derivatives were comparatively investigated by chemical methods, such as circular dichroism spectra, high performance anion exchange chromatography, high-performance gel permeation chromatography and fourier transform infrared spectrometry, and hydroxyl radical assay, DPPH radical assay and β-carotene-linoleic acid assay, respectively.

TL;DR: In this article, the main methods of sulfated modification, structural changes and the bioactivities of polysaccharide derivatives are reviewed, in order to reveal the potential mechanism of sulfation on bio-activities.

TL;DR: MAE was a suitable approach for the selective extraction of flavonoids from C. paliurus (Batal.) Iljinskaja leaves and showed a strong DPPH radical-scavenging ability, according to in vitro antioxidant assays.

TL;DR: Results indicated that the acetylated derivative Ac-CP could enhance the activation of peritoneal macrophages, and acetylation modification can enhance the immunomodulation function of CP, indicating the potential application of acetylations polysaccharide as an immunotherapeutic adjuvant.
