Özet
One new oleanane-type saponin, 3-O-beta-D-glucopyranosyl-(1 -> 4)-beta-D-xylopyranosyl-(1 -> 3)-alpha-D-rhamnopyranosyl-(1 -> 2)-alpha-L-arabinopyranosylhederagenin 28-O-beta-D-glucopyranosyl-(1 -> 6)-beta-D-glucopyranosyl ester (1) was isolated from the MeOH extract of whole plant parts of Cephalaria aristata C. Koch along with three known oleanane-type saponins, 3-O-alpha-L-rhamnopyranosyl-(1 -> 2)-alpha-L-arabinopyranosyl hederagenin 28-O-(beta-D-glucopyranosyl-(1 -> 6)-beta-D-glucopyranosyl) ester (2), 3-O-beta-D-glucopyranosyl-(1 -> 4)-beta-D-xylopyranosyl-(1 -> 3)-alpha-L-rhamnopyranosyl-(1 -> 2)-alpha-L-arabinopyranosyl hederagenin (3) and 3-O-alpha-L-rhamnopyranosyl-(1 -> 2)-alpha-L-arabinopyranosylhederagenin (4). Also three triterpenoids and a steroid glucoside oleanolic acid (5), beta-amyrin (6), 20-beta-hydroxyursolic acid (7) and 29-hydroxystigmast-5-en-3-O-beta-D-glucopyranoside (8). Their structures were established by the extensive use of 1D-and 2D-NMR experiments along with ESIMS and HRMS analysis.
