Sea cucumbers have been valued for many centuries as a tonic and functional food, dietary delicacies and important ingredients of traditional medicine in many Asian countries. An assortment of bioactive compounds has been described in sea cucumbers. The most important and abundant secondary metabolites from sea cucumbers are triterpene glycosides (saponins). Due to the wide range of their poten...

Abstract Sea cucumber was a marine invertebrate from class Holothuroidea and phylum Echinoderm that possessed various bioactive compounds. This study aimed to estimate the antioxidant properties of sea cucumbers evaluate their ability. Ferric Reducing Antioxidant Power (FRAP) Cupric Capacity (CUPRAC) assay estimated cucumbers, for control, ascorbic acid Trolox were used. The samples dried Holot...

The cytotoxic effects of thirteen triterpene glycosides from Holothuria scabra Jaeger and Cucumaria frondosa Gunnerus (Holothuroidea) against four human cell lines were detected and their cytotoxicity-structure relationships were established. The apoptosis-inducing activity of a more potent glycoside echinoside A (1) in HepG2 cells was further investigated by determining its effect on the morph...

Aspects of asexual reproduction in holothurians are discussed. Holothurians are significant as fishery and aquaculture items and have high commercial value. The last review on holothurian asexual reproduction was published 18 years ago and included only 8 species. An analysis of the available literature shows that asexual reproduction has now been confirmed in 16 holothurian species. Five addit...
