Currently, the introduction of value-added sea cucumber products to the global market has inspired basic research on frondoside A and other saponins in sea cucumbers. These saponins serve as a means of their chemical defence. However, recent studies revealed that exposure to these saponins can lead to irritating symptoms from aerosolization of various holothurins. Moreover, extraction methods are critical to the bioavailability of various bioactive compounds found in sea cucumbers. Therefore, we have critically reviewed recent studies on the chemistry, biosynthesis, and pharmacological properties of frondoside A. Furthermore, the mechanism of actions of frondoside A was postulated and further studies are required for applications in functional foods, nutraceuticals, and pharmaceuticals. Frondoside A was first discovered from Cucumaria frondosa, and it is involved in protein kinase (PI3K/AKT/ERK1/2/p38 MAPK, RAC/CDC42 PAK1, NFκB/MAPK/JNK, and LXR-β) signalling pathways.
