In the present study, bee pollen polysaccharides from Rosa rugosa (WRPP) were extracted and fractionated. WRPP were purified to neutral (WRPP-N) and acidic polysaccharides (WRPP-1, WRPP-2) with DEAE-Cellulose. WRPP-N were mainly composed of glucose, mannose, arabinose and galactose, indicating the existence of glucan, arabinogalactan (AG) and mannoglucan. WRPP-1 mainly consisted of rhamnose (3.0%), galacturonic acid (12.4%), galactose (24.7%) and arabinose (53.9%), and contained a large… Expand
Polysaccharide structure and immunological relationships of RG-I pectin from the bee pollen of Nelumbo nucifera.
TLDR
The results suggest that Gal side chain residues may play a crucial role in macrophage phagocytosis, whereas Ara is unimportant for NO production and neither Gal nor Ara impact lymphocyte proliferation. Expand
Antioxidant and immunomodulatory activities in vitro of polysaccharides from bee collected pollen of Chinese wolfberry.
TLDR
It is suggested that WBPPS-3 has potential to be developed as antioxidant and immunomodulatory ingredients in functional foods, but further animal or clinical studies are required. Expand

Storage methods, phenolic composition, and bioactive properties of Apis mellifera and Trigona spinipes pollen
TLDR
In general, the bee pollen produced by T. spinipes presented highest antioxidant activity in dried and fresh samples assessed either by test of plasma ferric reduction capacity (FRAP) and free radical scavenging assay (DPPH) methods, and for A. mellifera bee pollen the antioxidant activity was higher on the fresh samples.

TLDR
In contrast to crude pollen extracts, the immunological properties of the arabinogalactan mixture reveal an IgG4 reactivity instead of IgE reactivity, which might influence the immune response. Expand

Further analysis of the structure and immunological activity of an RG-I type pectin from Panax ginseng.
TLDR
The bioactivity assay showed that the arabinogalactan side chains of WGPA-2-RG are essential structures for stimulating NO secretion and lymphocyte proliferation, however, removal of the Ara and Gal residues through hydrolysis did not appreciably affect the ability of W ginseng polysaccharides to enhance macrophage phagocytosis.

TLDR
Two polysaccharides isolated from the dried powdered roots of Vernonia kotschyana induced chemotaxis of human macrophages, T cells and NK cells and the enzyme resistant part of Vk100A2a still showed strong complement fixating activity, suggesting that this activity may at least in part be expressed by carbohydrate structures present in the enzymes resistant, inner portion of the polymer.
