Asr. Anjaneyulu et al., A NEW STEROID GLYCOSIDE FROM THE SEA-CUCUMBER HOLOTHURIA-SCABRA OFF MANDAPAM COAST, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 34(7), 1995, pp. 666-668
A new steroidal glycoside has been isolated along with 22,25-oxidoholo
thurinogenin (1), holothurinogenin (2), 25-methoxyholothurinogenin (3)
and 25-hydroxyholothurinogenin (4) from the methanolic extract of the
sea cucumber Holothuria scabra. The structure of the new glycoside ha
s been determined as 24,26-dimethylcholest-5-ene-3 beta-O-xylopyranosi
de (5) by a study of its physical and spectral data (UV, IR, H-1 NMR,
C-13 NMR and Mass) and chemical degradation.
