摘要：
Two novel triterpenoid saponins, Snatzkein C, (3 beta,20-dihydroxylupan-28-oic acid 3-O-[beta-D-gal actopyranosyl-(1 --> 2)-beta-D-glucopyranosyl]-28-O-beta-D-glucopyranoside) and SnatzkeinD, (3 beta,20-dihydroxy-lupan-28-oic acid 3-O-[beta-D-glucopyranosyl-(1 --> 2)-beta-D-glucopyranosyl]-28-O-beta-D-glucopyranoside) have been isolated from Arenaria filicaulis. Their structure and conformational behaviour were elucidated by one- and two-dimensional H-1 NMR and C-13 NMR spectroscopy. (C) 1998 Elsevier Science Ltd. All rights reserved.
