Lactones absinthium

Absinthin, the active principle of wormwood, Artemisia absinthium L. (Compositae), is a dimeric guaianolide containing two lactone rings and two hydroxy groups per molecule.162 Thelephoric acid (76b), isolated from fungi of several Thelephora species, has been synthesized by oxidative condensation of two molecules of sodium 3,4-dimethoxy-phenoxide with one of chloranil in the presence of hydrobromic acid.162a... [Pg.37]

The main bitter component of wormwood Artemisia absinthium) is a dimeric sesquiterpenic lactone absinthin (8-252), which is produced by intramolecular cycloaddition (Diels-Alder reaction) probably of two molecules of astabisin (8-253), which is derived from guaiane. In wormwood extracts, absinthin is transformed into isomeric anabsinthin (8-254). The bitter taste of mugwort (A. vulgaris) is derived primarily from the related compounds estafiatin (8-255) and balchanin (8-256), which are... [Pg.646]
