Phytochemical investigation of the methanolic extract of the aerial parts of Artemisia absinthium Linn.
(Asteraceae) yielded four new phytoconstituents characterized as stigmast-5,22-dien-3β-ol-21-oic acid-3β-glucopyranosyl-2'-
octadec-9''-enoate (1); lanost-24-en-3β-ol-11-one-28-oic acid-21,23 α-olide-3β-D-glucopyranosyl-2'-dihydrocaffeoate-6'-
decanoate (2); tricosan-14-on-1,4-olide-5-eicos-9'-enoate (3) and 3,11-dimethyldodecan-1,7-dioic acid-1-β-D-glucopyranosyl-6'-
octadec-9''-enoate (4). The structures of these phytoconstituents have been elucidated on the basis of spectral data analysis
and chemical reactions.
Keywords: Artemisia absinthium, asteraceae, glycoside ester, lanostenolide, stigmastane.
