description Two novel triterpenoid saponins, Snatzkein C, (3 β,20-dihydroxylupan-28-oic acid 3- O-[ β- d-galactopyranosyl-(1 → 2)- β- d-glucopyranosyl]-28- O- β- d-glucopyranoside) and SnatzkeinD, (3 β,20-dihydroxylupan-28-oic acid 3- O-[ β- d-glucopyranosyl-(1 → 2)- β- d-glucopyranosyl]-28- O- β- d-glucopyranoside), have been isolated from Arenaria filicaulis. Their structure and conformational behaviour were elucidated by one- and two-dimensional 1H NMR and 13C NMR spectroscopy.
