Abstract:
Helianthus is a genus belonging to the Asteraceae family. It includes species such as Helianthus annuus L. and H. tuberosus L., and is widely grown worldwide. Helianthus polysaccharides (HPs) are bioactive compounds applied in food, medicine, and agriculture. They possess radioprotective, antitumor, hypoglycemic, anti-obesity, and antiviral activities, besides protecting the intestinal mucosal barrier. This study aimed to summarize recent advances in HPs, encompassing their extraction, purification, structure, pharmacological activity, structure-activity relationships, and applications. It also examined current patents to clarify the mechanisms underlying the effects of HPs and identified research gaps to guide future studies on sunflower and other plant-derived polysaccharides.
