1. 1. Glycoside fractions from thirty-four sea cucumber species were isolated by means of precipitation with cholesterol and subjected to a comparative examination. 2. 2. Previously unknown triterpene glycosides were detected in the genera Bohaschia, Stichopus, Thelenota, Cucumaria and Afrocucumis. 3. 3. Glycoside fraction hydrolysis products were investigated. 4. 4. A relationship was established between the systematic position of the animal and its glycoside content. The families… Expand
Glycosides of marine invertebrates—VI. Steroid glycosides from holothurian Stichopus japonicus
Abstract 1. 1. Steroid glycosides from holothurian Stichopus japonicus Selenka were investigated. The β-monoside fraction has been isolated by chromatography on silica gel columns with subsequentExpand
Glycosides of marine invertebrates. III. Biosynthesis of stichoposides from acetate.
The labelled acetate contained in the organism of the holothurian Stichopus japonicus can transform into triterpene glycosides, which resulted in a labelled aglycon of the lanosthane row, namely stichopogenin A4. Expand
Effect of marine glycosides on adenosinetriphosphatase activity.
Marine glycosides from the sea cucumbers inhibit both Na+-K+ ATPase and Mg2+-ATPase of rat brain in vitro and the glycoside-cholesterol complex of these compounds does not influence ATPase activity. Expand
Triterpene Glycosides of Sea Cucumbers (Holothuroidea, Echinodermata) as Taxonomic Markers
The advantages and problems in the use of triterpene glycosides as taxonomic markers in the systematics of sea cucumbers are discussed. Expand
Studies on the distribution, biosynthesis and function of steroidal saponins in echinoderms.
Large quantities of saponin are present in the Asteroidea (starfish), with only trace amounts in the Ophiuroidea, Echinoidea and CrinoideA, and a relationship exists between the taxonomic position of a starfish and the composition of its sap onin aglycone fraction. Expand
Triterpene glycosides from sea cucumber Stichopus japonicus Selenka.
The previously-established difference in glycoside structures between Stichopus japonicus and other representatives of the family Stichopodidae was corroborated. Expand
Mechanism of cytotoxic action of some triterpene glycosides.
The cytotoxic activity, in sea urchin embryos, of the triterpene glycosides and inhibition of macromolecule synthesis appeared to be due to an alteration in the selective permeability of the cytoplasmic membrane. Expand
Structure elucidation of five novel isomeric saponins from the viscera of the sea cucumber Holothuria lessoni.
The structure of seven reported triterpene glycosides, including sulfated and non-sulfated saponins containing a range of aglycones and sugar moieties, from the viscera of the Australian sea cucumber Holothuria lessoni are elucidated. Expand
Review of saponin diversity in sea cucumbers belonging to the family Holothuriidae
All of the data combined indicate a complex chemical defence mechanism with different sets of saponins originating from different body compartments and presenting different properties in relation to their ecological role(s). Expand
Glycosides of marine invertebrates. Structure of holothurin A2 from the holothurianHolothuria edulis
The structure of a new glycoside fromHolothuria edulis, holothurin A2, has been established with the aid of periodate oxidation, methylation, Smith degradation, and13C NMR spectroscopy. The structureExpand


A New Saponin, Holothurin B, Isolated from Sea-Cucumber, Holothuria vagabunda and Holothuria lubrica
Two species of sea-cucumber were found to contain an unknown saponin component besides the major one identical with holothurin A isolated by Chanley from Actinopyga agassizi. The unknown componentExpand
