Abstract

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

key words
