The present review paper is a continuation of the previous paper dealing with the glycosides of
Solidago virgaurea L. It summarized the knowledge about saponins present in both Solidago
canadensis L. and Solidago gigantea Ait. var. serotina (O. Kuntze) Cronquist. From S. canadensis,
eight saponins, i.e. canadensissaponins, have been isolated till now. From S. gigantea, four
giganteasaponins have been isolated. The saponins of S. canadensis and S. gigantea are of
bidesmosidic type and differ from one another in the length and structure of saccharide chains.
These chains are not acylated as the saponins of S. virgaurea. Giganteasaponins differ from
canadensissaponins in three saccharide units bonded to the C 3 of bayogenin. New information about
the inflammatory and antioxidative activities of their extracts are also presented.
