Özet

Four new triterpene glycosides, named oleanazuroside 1 (1), oleanazuroside 2 (2), ursolazuroside 1 (3), and ursolazuroside 2 (4), together with the seven known compounds 5-11, were isolated from the MeOH extract of the aerial parts of Anchusa azurea Miller var. azurea. Their structures were elucidated by means of spectroscopic evidence (UV, IR, MALDI-MS, and 1D- and 2D-NMR). The radical-scavenging activities against 2,2-diphenyl-1-picrylhydrazyl (DPPH) of the BuOH extract and of 8 and 10 were very strong (Table 5). © 2010 Verlag Helvetica Chimica Acta AG.
