The detailed investigation of a methanolic extract of aerial parts of Achillea nobilis resulted in the isolation of 10 flavonoids. A new C-glycosylflavone, luteolin-6-C-apiofuranosyl-(1‴→2″)-glucoside, was isolated besides orientin, isoorientin, vitexin, isoschaftoside, luteolin- 7-O-β-glucuronide, luteolin-4′-O-β-glucoside and quercetin-3-O-methyl ether and two rare flavonolglycosides, quercetin-3-O-α-arabinosyl-(1‴→6″ )-glucoside and quercetin-3-O-methylether-7-O-β-glucoside. The structures were established either by comparison with authentic substances or by UV, 1H NMR and 13C NMR spectroscopic methods including 2ᴅ-NMR techniques and ESI-MS
