Abstract: A new norpentacyclic triterpenoid, auriculatone, was isolated from Aster auriculatus Franch.On the basis of physico-chemical constants, spectral data and X-ray diffraction analysis of 3β-acetoxy derivative (Ⅱ), its structure was determined as 3β-hydroxy-17α-H,18β-H-28-norolean-12-ene-16-one (Ⅰ).

Key words: Aster auriculatus Franch, Auriculatone, Norpentacyclic triterpenoid
