Phytoecdysteroids of plants of the Silene genus. XIX. The structure of sileneoside G

Article abstract of DOI:10.1007/BF02319284

The phytoecdysteroid sileneoside G has been isolated from the roots of Silene brahuica Boiss., and its structure has been established on the basis of chemical transformations and spectral characteristics as ecdysterone 3-O-α-D-galactopyranoside 22-O-α-D-glucopyranoside. Enzymatic hydrolysis yielded ecdysterone and sileneoside D.
