Abstract
The steroid glycoside fraction ofIsostichopus badionotus, consisting of a mixture of D-xylosides of steroid alcohols, has been isolated by column chromatography on silica gel. The mixture of aglycones obtained after acid hydrolysis was separated with the aid of argentation chromatography into several fractions. GLC-MS analysis, and also the use of IR and13C NMR spectroscopy has shown that the steroid glycosides ofI. badionotus are xylosides of Δ0-, Δ7-, Δ22-, and Δ7.22-, C27-, C28-, and C29-steroids of the cholestane series.
