A novel triterpenoid saponin, Snatzkein E, was isolated from Arenaria filicaulis Boiss. It possesses a new aglycone and a glucose moiety carrying a sulfate group at C-2′. Its structure and conformational behaviour were investigated by one- and two-

Scheme 1. Structures of Snatzkein A (1) and B (2) ents of Arenaria Ðlicaulis we realized that the structure of glycoside 2 is wrong. A negative FAB-MS measurement proved unequivocally that the substituent at the oxygen atom of C-2@ is not but a sulR
