A new phenolic glycoside, asterbatanoside A [p-hydroxyacetophenone-4-O-β-D-xylopyranosyl-(1 → 6)-β-D-glucopyranoside], and two new triterpenoid saponins, asterbatanoside B [2α,3β,23-trihydroxyolean-12-en-28-oic acid-28-O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranoside] and asterbatanoside C [3-O-β-D-glucopyranosyl-2β,3β,23-trihydroxyolean-12-en-28- oicacid-28-O-β-D-glucopyranoside] were isolated from the roots of Aster batangensis. Their structures were determined by spectroscopic methods and chemical evidence. The total synthesis of asterbatanoside A is also reported. Copyright
