“…Polysaccharides are a kind of biopolymer composed of numerous monosaccharides linked by glycosidic bonds (Hashemifesharaki et al, 2020). In the past few decades, it has generated a keen interest in polysaccharides from plants, animals, and microorganisms due to their diverse and potential bioactivities, such as immune regulation (Surayot et al, 2019), antiradiation (Ye et al, 2018), antioxidation (Qiao et al, 2021), antitumor (Chen & Xue, 2019), and so on. Hence, these active polysaccharides were widely used as functional ingredients to enrich various foods and pharmaceutical supplements (Taghi & Sara, 2017).…”

A novel polysaccharide (PCPP‐1A) from Poria cocos peels was prepared and its structural characterization and biological activities were investigated in vitro. The optimized extraction conditions of PCPP that obtained by response surface methodology were liquid to solid ratio 24.19 ml/g, extraction time 5.54 h, and extraction temperature 100°C, with the highest yield of 0.71%. Moreover, the crude PCPP was further separated by anion‐exchange chromatography and gel permeation chromatography to obtain the purified PCPP‐1A. Structural characterization showed that PCPP‐1A had an average molecular weight of 45.38 kDa and was composed of mannose, glucuronic acid, glucose, galactose, and fucose in a molar ratio of 10.93:1.00:235.76:26.99:6.56. The results of NMR indicated that PCPP‐1A might possess pyranoid glucose connected by α‐type and β‐type glycosidic bonds. Furthermore, PCPP‐1A existed excellent potential on stimulating immune response of RAW264.7 cells and protecting AML‐12 cells against radiation. These results indicated that PCPP‐1A had underlying application value in the development of functional foods.

Bee pollen has been traditionally used for health promotion. However, the chemical constituents and pharmaceutical effects of bee pollen strongly depend on their sources. This study determined chemical compositions and evaluated the antioxidant and anticancer activity of six bee pollen samples from Taiwan. The Cs sample contained the highest amounts of carotenoid (417.67 mg/g DW) and anthocyanin (10.96 μmol/g DW) while the Nn sample showed the highest content of chlorophyll (Chl) a (23.39 mg/g DW) and Chl b (39.17 mg/g DW). The highest flavonoid (11.69 mg QE/g DW) and phenolic content (42.91 mg GAE/g DW) were found in Bp and Pm samples, respectively. The highest Fe2+-chelating ability was observed in Bp (IC50 value of 6.28 mg/mL), while Bn exhibited the most effective in scavenging DPPH radical with IC50 value of 3.96 mg/mL. The Bp sample also showed the highest activity against three breast cancer cell lines, MCF-7 (cell viability of 43.5%), BT-20 (cell viability of 0%), and Hs 578T (cell viability of 0%). This study suggested that the level of bioactive compounds and biological activity of bee pollen significantly differ among their sources and the Bp is a potent antioxidant and anticancer agent for medicinal use.
