초록

Being an agarophyte, Gelidium is extensively exploited for its agar-producing capacity. However, the food value and medicinal importance of this red alga are not to be underestimated. The pharmacological properties of Gelidium species have potential for the pharmaceutical, nutraceutical and cosmeceutical industries. This review collects, identifies and analyzes comprehensively the studies that deal with the bioactive properties of Gelidium species in the last decade. The principal bioactive compounds of Gelidium include R-phycoerythrin, R-phycocyanin, alkaloids, terpenoids, tannins, flavonoids, saponins, coumarins, cardiac glycosides, and steroids. Gelidium in the form of extracts or isolated compounds have been reported to show antibacterial, antioxidant, anticancer, anti-inflammatory, anti-obesity, immunomodulatory, neuroprotective, and antidiabetic properties. Most of the evidence has been reported in various in vitro models. Therefore, further experiments using appropriate animal and human subjects are necessary to develop the preclinical findings into clinical use. The main challenge in developing bioactive compounds on a commercial scale is the sustainable supply of Gelidium biomass that requires integrated seaweed aquaculture through employing biotechnological approaches and effective utilization of industrial byproducts. © 2023, The Author(s), under exclusive licence to Springer Nature B.V.
