ABSTRACT
In the current study, a total of nineteen triterpenoids (1-19) from 60% EtOH extracts of Stauntonia obovatifoliola Hayata subsp. intermedia stems were separated and purified by solvent extraction and chromatographic methods including silica gel, ODS as well as preparative HPLC. According to the results of chemical reactions and spectral data, compounds were identified as lupeol (1), betulinonic acid (2), betulinic acid (3), 3-epi-betulinic acid (4), quinatic acid (5), 24-O-acetyl quinatic acid (6), 3-O-α- L-arabinopyranosyl-30-nor-hederagenin-28-O-α-L-rhamnopyranosyl-(1 --> 4) -β-D-glucopyranosyl-(1 --> 6) -β-D-glucopyranosyl ester (7), Stauntoside A (8), kalopanax saponin A (9), kalopanax saponin J (10), Kizuta saponin K10 (11), 3-O-α-L-rhamnopyranosyl (1--> 2) -α-L-arabinopyranosyl-hederagenin-28-O-β-D-xylopyranosyl-(1 --> 6) -β-D-glucopyranosyl ester (12), kalopanax saponin B (13), 3-O-α-L-rhamnopyranosyl-(1 --> 2) -α-L-arabinopyranosyl-hederagenin-28-O-β-D-glucopyranosyl-(1 --> 6) -β-D-glucopyranosyl ester (14), sieboldianoside A (15), septemoside A (16), kalopanax saponin K (17), septemloside I (18), and 3-O-α-L-arabinopyranosyl (1 --> 2)-β-D-glucuronopyranosyl- hederagenin (19). Among them, compounds 4, 6, 10, 12, 14, and 16-19 were isolated from the Stauntonia genus for the first time, and compound 6 was a new natural product.
