Abstract
Two new triterpenoid saponins named asterbatanoside D and E have been isolated from Aster batangensis and their structures elucidated as 3-O-beta- D-glucopyranosyl-bayogenin-28-O-beta-D-glucopyranosyl-(1-->6)-beta -D- glucopyranoside and 3-O-6'-acetyl-beta-D-glucopyranosyl-bayogenin-28-O-beta-D- glucopyranosyl-(1-->6)-beta-D-glucopyranoside by means of MS, 1D and 2D NMR techniques (COSY, TOCSY, ROESY, HMQC, and HMBC), and chemical reactions.Entities:
