glycosides, of which the more polar one greatly predominated, and also trace amounts of still more polar glycosides. The isolation of the main steroid glycoside (SG) was achieved by defardng the carefully ground seeds with hexane, followed by exlraction with 80% isopropyl alcohol. Evaporation of the alcoholic extract gave a 20% total yield of unpurified glycosides. Crystallization of this mixture from ethanol enabled the main glycoside to be obtained in the practically pure state with a yield… 
Structure, Bioactivity and Analytical Methods for the Determination of Yucca Saponins
An exhaustive review of the structural characteristics, bioactivities and analytical methods that can be used with these compounds has been carried out, indicating that the identification of saponins present in Yucca genus is still an unresolved question.

Gold mediated sp3αC-H functionalization of steroidal diglycoside and their anti-cancer evaluation
The original form of SG and its derivatives and their derivatives were screened for in vitro anti-cancer activity specifically on two breast cancer cell lines and deduced the structure-activity-relationship with the support of molecular docking studies.


Molluscicidal saponins from cornus florida L.
The molluscicidal principle of Cornus florida L. (Cornaceae) has been isolated from the methanolic bark extract by droplet counter-current chromatography (DCC). The structure of the active compounds
