Structure of cucumarioside G2, a novel nonholostane glycoside from the sea cucumber Eupentacta fraudatrix.
The new triterpene glycoside cucumarioside G2 [1] has been isolated from the sea cucumber Eupentacta fraudatrix. Glycoside 1 is the first triterpene glycoside with the 23,24,25,26,27-pentanorlanostane type of aglycone. Its structure has been established by chemical transformations as well as 13C- and 1H-nmr, eims, and liquid sims studies.
