摘要:

Two novel triterpenoid saponins named asterbatanoside F (1) and G (2) were isolated from the roots ofAster batangensisand their structures elucidated as 3-O-β-D-glucopyranosyl-23-O-acetyl-bayogenin-28-O-β-D- glucopyranosyl-(1 → 6) - [α-L-rhamnopyranosyl-(1→2)] β-D-glucopyranoside and 3-O-β-D-glucopyranosyl-bayogenin-28-O-β-D-glucopyranosyl-(1→6)-[α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside by means of spectral data especially 2D NMR including COSY, HETCOR, COLOC, HOHAHA, ROESY and selective INEPT techniques and chemical evidence.
