Flavonoids from Achillea nobilis L.

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-beta-glucuronide, luteolin-4'-O-beta-glucoside and quercetin-3-O-methyl ether and two rare flavonolglycoside...

Achillea millefolium L. – phytochemical profile and in vitro antioxidant activity

Nowadays, medicinal plants used in folk medicine are being increasingly studied and used on pharmaceutical, food and nutraceutical fields. Yarrow (Achillea millefolium L.) is widely used in both folk and official medicine. Therefore, in the present paper different extracts of yarrow inflorescences and upper leaves were investigated for their total polyphenolic content and antioxidant activity u...

Phenolic compounds from Achillea millefolium L. and their bioactivity.

Since antiquity, Achillea millefolium L. (Asteraceae) has been used in traditional medicine of several cultures, from Europe to Asia. Its richness in bioactive compounds contributes to a wide range of medicinal properties. In this study, we assessed A. millefolium methanolic extract and its isolated components for free radical scavenging activity against 2,2-diphenyl-pycrilhydrazyl, total antio...

N ov 1 99 2 Multiple W L Production From Inelastic W L W L Scattering At √ ŝ ≫

We explore the inelastic production of multiple longitudinal weak bosons as a manifestation of a strongly interacting symmetry breaking sector. By analogy with QCD, final states with large multiplicities are expected to occur not far above the energy scale of the lowest resonances of the underlying strong theory. We consider the feasibility of observing such phenomena in the environment of a ve...
