Abstract:
Two new triterpenoid saponins named asterlingulatosides A and B were isolated from the whole plants of Aster lingulatus. Their structures were determined by spectroscopic data and chemical transformations to be 3-O-beta-D-glucopyranosyl-3 beta,16 alpha-dihydroxyolean-12-en-28-oic acid-28-O-alpha-L-O-arabinopyranoside and 3-O-beta-D-glucopyranosyl-3 beta,16 alpha-dihydroxyolean-12-en-28-oic acid-28-O-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranoside++ +. They showed inhibitory activity on DNA synthesis in human leukaemia HL-60 cells.
