New Coumarin-Hemiterpene Ether Glucosides and a Structurally Related Phenylpropanoic Acid Derivative from Artemisia Armeniaca

Two new coumarin-hemiterpene ether glucosides, 4’-O-(β-D-glucopyranosyl) desoxylacarol (1), and 5-O-(β-D-glucopyranosyl) lacarol (2), were isolated from the methanolic extract of the aerial parts of Artemisia armeniaca Lam. Their structures were established by means of spectroscopic analysis including 1H- and 2D-NMR, HRESIMS, and acid hydrolysis. In addition, a structurally related phenylpropanoic acid derivative (3) was obtained in small amounts, and its structure tentatively assigned as 3-(4-hydroxy–3-methylbutoxy)-4-methoxy melilotic acid.
