New antimicrobial metabolites from the medicinal herb Artemisia herba-Alba

2019

Artemisia herba-alba is widely used in traditional medicines for the treatment of several diseases. From the aerial parts organic extract of A. herba-alba, two new compounds, 1,3,8-trihydroxyeudesm-4-en-7α,11βH-12,6α-olide (1) and 5-β-D-glucopyranosyloxy-7-methoxy-6H-benzopyran-2-one (2), respectively, together with five known metabolites: 3α,8β-dihydroxygermacr-4(15),9(10)-dien-7β,11αH,12,6α-olide (3), 1β,8α-dihydroxy-11α,13-dihydrobalchanin (4), 11-epiartapshin (5), tomenin (6) and benzoic acid, p-(β-D-glucopyranosyloxy)-methyl ester (7), were isolated and identified. The chemical structures were proven depending upon spectroscopic analysis, including 1 D/2D NMR as and ESI-MS…
