Four new triterpene glycosides, colochirosides A₁ (1), A₂ (2), A₃ (3) and D (4), have been isolated from the sea cucumber Colochirus robustus (Cucumariidae, Dendrochirotida). Structures of the glycosides have been elucidated by 2D NMR spectroscopy and mass-spectrometry. Colochiroside D (4) has a new type of carbohydrate chain having the only sulfate group attached to C-6 of the third (glucose) monosaccharide residue. Cytotoxic activities of glycosides 1-4 against the ascite form of mouse Ehrlich carcinoma cells and hemolytic activity against mouse erythrocytes have been studied. Hemolytic activity of the glycosides was higher than cytotoxic. Glycosides 1, 3 and 4 demonstrated strong effects, whereas compound 2 showed only moderate activity.
