Abstract
The new diguaianolide anabsin, C30H40O7, mp 276°C (decomp.), [α]25 +110° (c 1.7; acetone) has been isolated fromArtemisia absinthium L. Anabsin acetate, dehydroanabsin, and dehydroanabsin acetate have been obtained. A comparative study of the1H and13C NMR spectra of anabsin, absinthin, and anabsinthin has been made. The structure of anabsin has been established and structures have been suggested for absinthin and anabsinthin. The most probable biogenesis of anabsin in plants has been put forward.
