Jewel of the seabed: sea cucumbers as nutritional and drug candidates

Abstract

Marine sources have been attracting the attention of scientists and manufacturers worldwide hoping to find new alternatives for biological active substances. Promising new research indicates that sea cucumber, which is slug-like in appearance and has been a staple in Japan, China and other parts of East Asia since ancient times, is beginning to gain popularity as a dietary supplement in western countries. The roles of sea cucumber extracts in various physiological functions have spurred researchers to investigate the ability of sea cucumber to be an alternative in neutraceutical and medical applications. This article provides a brief introduction to sea cucumber and reviews its numerous bioactive compounds, such as triterpene glycosides, glycosaminoglycans, gangliosides, collagen, branched-chain fatty acid and lectins, which serve as potential sources of neutraceutical, pharmaceutical and cosmetic agents, thus providing a new platform in biochemical research.
