Rare hydroperoxyl guaianolide sesquiterpenes from Pulicaria undulata

Pulicaria species, such as Pulicaria undulata, are rich in sesquiterpene lactones. The methylene chloride/ methanol (1:1) extract of P. undulata resulted in the isolation of new sesquiterpenes (1–4), as well as previously reported metabolites (5–14). Structures were elucidated by spectroscopic analyses. Using a mouse peritoneal macrophage bioassay, lipopolysaccharide-induced nitric oxide inhibi...

Cytotoxic and insect -repellent activities of surface flavonoids from Datura stramonium L. Grown in Egypt

Three flavonoidal aglycones viz; F1 (Chrysin), F2 (Kampferol) and novel F3( 3,7dimethylether quercetin), were isolated from acetone wash of fresh leaves of Datura stramomium L. Isolated compounds were identified on the basis of their physico-chemical properties, Co-TLC, H-NMR, C-NMR and CIMS specrtum. Significant cytotoxic activity against three tumor cell lines (liver, cervix & breast), was re...

Geographical variation in the surface flavonoids of Pulicaria dysenterica.

Four chemical races were detected in Pulicaria dysenterica, when sampled within Europe, on the basis of the surface flavonoids present. One race uniquely contained quercetagetin 3,7-dimethyl ether and another 6-hydroxykaempferol 3,4'-dimethyl ether. A third race was based on plants having 6-hydroxykaempferol 3,7-dimethyl ether together with quercetagetin 3,7,3'-trimethyl ether. The fourth race ...

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...
