Ariensin, a new lignan from Bursera ariensis.
From acetone extracts of the exudate of the tree Bursera ariensis, a new bilignan, named ariensin, has been isolated and characterized as (2R,3R)-bis-2.3-(3.4-methylenedioxybenzyl-)-1.4-butanediol diacetate. The structure has been determined from UV, IR, (1)H-NMR and (13)C-NMR data of the natural product, the dibromo derivative and the hydrolysis product. The optical rotation of the latter allowed the determination of the absolute configuration.
