متن کاملRare 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...
متن کاملInvestigation the protective ability of Pulicaria. undulata aqueous extract on aggregation of κ -casein
Protein aggregation is phenomenon wherein protein loses its native structure and aggregates due to the adaption of non-native conformation. Amyloid aggregation formed by the accumulation of various proteins causes many diseases in humans and other organisms. Antioxidants can prevent proteins aggregation. Pulicaria undulata extract along with phenolic compounds can increase protein stability an...
متن کاملGenetic variability characterization of the Moroccan Houbara Bustard (Chlamydotis undulata undulata) inferred from pedigree analysis.
A Moroccan Houbara Bustard pedigree was analyzed to evaluate the genetic variability in captive breeding population using genealogical approaches. The whole Houbara breeding flock (WP) for the period 1993-2004 was made up of 531 birds comprising 346 females and 185 males. The reference population (RP) comprised 198 individuals ready for reproduction from 2000 to 2004 cohorts. The corresponding ...
متن کاملPhenolic compounds with antioxidant activity from Anthemis tinctoria L. (Asteraceae).
From the aerial parts of Anthemis tinctoria L. subsp. tinctoria var. pallida DC. (Asteraceae), one new cyclitol glucoside, conduritol F-1-O-(6'-O-E-p-caffeoyl)-beta-D-glucopyranoside (1), has been isolated together with four flavonoids, nicotiflorin (2), isoquercitrin (3), rutin (4) and patulitrin (5). The structures of the isolated compounds were established by means of NMR, MS, and UV spectra...
