Three new holostan-type triterpene glycosides, arguside F (1), impatienside B (2), and pervicoside D (3), together with a known saponin, holothurin B ( 4) were isolated from the sea cucumber Holothuria (Microthele) axiloga H. L. Clark. On the basis of spectroscopic data and chemical reactions, the structures of the new compounds were elucidated. Compound 2 showed significant antifungal activities against six strains (1 < or = MIC(80) < or = 4 microg/mL). The stereochemistry of holothurin B (4…

Antifungal nortriterpene and triterpene glycosides from the sea cucumber Apostichopus japonicus Selenka.

Analysis of saponins as bioactive zoochemicals from the marine functional food sea cucumber Bohadschia cousteaui

Twenty-one lanostane-type non-sulphated triterpene glycosides were isolated from the methanol/methylene chloride extract of the body walls of Bohadschia cousteaui and showed good antifungal activity against Candida albicans.

Holothuria triterpene glycosides: a comprehensive guide for their structure elucidation and critical appraisal of reported compounds

Sea cucumbers or holothurians are marine invertebrates, belonging to the phylum Echinodermata (kingdom Animalia). In Asia, they are commonly used as food, while they are applied in traditional…

Acetylated Triterpene Glycosides and Their Biological Activity from Holothuroidea Reported in the Past Six Decades

The structure of acetylated saponins, their biological activity, and their structure-activity relationships are highlighted; including induction of caspase, apoptosis, cytotoxicity, anticancer, antifungal and antibacterial activities of these compounds.

Biological and taxonomic perspective of triterpenoid glycosides of sea cucumbers of the family Holothuriidae (Echinodermata, Holothuroidea).

Sea Cucumber Glycosides: Chemical Structures, Producing Species and Important Biological Properties

Understanding on diverse chemical structures of triterpene glycosides from various species of sea cucumbers and their important biological activities are updated and summarized.

Saponins from Sea Cucumber and Their Biological Activities.

This review summarizes current research on the structure and activities of sea cucumber saponins based on the physiological and pharmacological activities from source, experimental models, efficacy, and mechanisms, which may provide a valuable reference for the development ofSea cucumber Saponins.

Discovery of Novel Saponins from the Viscera of the Sea Cucumber Holothuria lessoni

At least 39 new saponins were identified in the viscera of H. lessoni with a high structural diversity, and another 36 reported triterpene glycosides, containing different aglycones and sugar moieties.

Distribution of Saponins in the Sea Cucumber Holothuria lessoni; the Body Wall Versus the Viscera, and Their Biological Activities

The structure of four novel acetylated saponins, namely lessoniosides H, I, J, and K were characterized and identified triterpene glycosides showed potent antifungal activities against tested fungi, but had no antibacterial effects on the bacterium Staphylococcus aureus.

Chemical Biodiversity and Bioactivities of Saponins in Echinodermata with an Emphasis on Sea Cucumbers (Holothuroidea)

The here presented data revealed that holothurians, holotoxins, cucumariosides, and echinosids are not only the most abundant saponin compounds in various genera of sea cucumbers but that these saponins can also be used as potential chemotaxonomic markers for different sea cucumber species.
