Abstract

The sesquiterpenoid alcohol, the so-called atractylol, a major constituent of the essential oil from the rhizomes of Atractylodes lancea DE CANDOLLE (Compositae), was separated into the known eudesmol and a new sesquiterpenoid alcohol, hinesol, which were characterised. Association of the two alcohols was established unambiguously by the regeneration of the so-called atractylol from them.

Abstract

Atractylon, the sesquiterpenoid oxide isolated from the rhizomes of Atractylodes japonica and its related plants (Compositae), has been proven to have constitution I on the basis of spectral properties and its conversion into 8, 12-oxido-eudesmane. Autoxidation of atractylon has given two crystalline compounds, the autoxidation product A and B, which have been established as shown in formulae (IV and V), respectively, from the degradative and spectral evidence.

4. Studies on the Constituents of Atractylodes. X. Correlation of Hinesol and β-Vetivone

Abstract

The enantiomer of β-vetivone (II) was synthesized from hinesol (I), via an α, β-unsaturated ketone (V), and its acetate (VII), and thus the absolute configurations of I and II were proposed as expressed by the formula (Ic) and (IIb) respectively.
