(), a perennial woody plant of the Araliaceae family, is extensive in Northeast China. Esteemed for both its medicinal and edible qualities in the Changbai Mountain region, its primary components include polysaccharides, saponins, and flavonoids. displays numerous pharmacological effects, such as cardiovascular protection, anti-tumour, anti-fatigue, and hypoglycaemic properties.

Research progress of edible mushroom polysaccharide-metal trace element complexes.

Metal trace elements are crucial for human health, and the complexes of edible mushroom polysaccharides with metal trace elements are currently a research hotspot in the field of food science. This article reviews the preparation methods, structural characterization, and physiological activities of edible mushroom polysaccharide-metal trace element complexes, including iron, selenium, and zinc. Research has shown that iron complexes obtained through Co-thermal synthesis of the FeCl method exhibit excellent antioxidant and anti-anemia functions; selenium complexes prepared via selenium-enriched cultivation significantly enhance immunological and anti-cancer properties; zinc complexes improve lipid-lowering, liver protection, and antioxidant capabilities.

Advancements in enzymatic biotransformation and bioactivities of rare ginsenosides: A review.

Ginsenoside, the principal active constituent of ginseng, exhibits enhanced bioavailability and medicinal efficacy in rare ginsenosides compared to major ginsenosides. Current research is focused on efficiently and selectively removing sugar groups attached to the major ginsenoside sugar chains to convert them into rare ginsenosides that meet the demands of medical industry and functional foods. The methods for preparing rare ginsenosides encompass chemical, microbial, and enzymatic approaches.
