ABSTRACT
Objective:
To study the constituents from the sea cucumber, Stichopus variegatus.Methods:
The crude saponins of S. variegatus were desulfated with pyridine-dioxane (11), the desulfated products were separated by multi-chromatography to afford two compounds.Results:
On the basis of chemical methods and spectral evidences, especially 2D-NMR and ESI-MS, these two compounds were identified as 3-0-[β-D-xylopyranosyl-(1→2)-4′-O- sulfate-β-D-xylopyranosyl]-holosta-9-ene-3β,12α,17α, 25β-tetraol sodium salt, named as variegatuside A (1) and 16β-acetoxy-3-O-β-D-xylopyranosyl-holosta-22,25-epoxy-9-ene-3β, 12α,17α-triol, named as variegatuside B (2).Conclusion:
