Cucumarioside E from the Far Eastern Sea Cucumber Cucumaria japonica (Cucumariidae,Dendrochirotida),New Minor Monosulfated Holostane Triterpene Pentaoside with Glucose as the Second Monosaccharide Residue
New minor triterpene glycoside, cucumarioside E (1) has been isolated from the Far Eastern sea cucumber Cucumaria japonica. The structure of the glycoside was elucidated by 2D-NMR specroscopy and mass-spectrometry. The glycoside has glucose instead of quinovose as the second monosaccharide residue and xylose as third monosaccharide residue that is unique structural feature for triterpene glycosides carbohydrate chains from sea cucumbers belonging to the genus Cucumaria.
