The antioxidant, hemolytic and cholinesterase inhibition properties of Galium verum L. and Tragopogon pratensis subsp. pratensis
The antioxidant properties of Galium verum L. (Lady’s Bedstraw) and Tragopogon pratensis subsp. pratensis (Goat’s beard) methanol extracts, from localities in Serbia were evaluated, through determination of total phenolics and flavonoids content, as well as DPPH • (1,1-diphenyl-2-picrylhydrazyl) radical scavenging, ABTS •+ (2,2-azinobis-(3ethylbenzthiazoline-6-sulfonic acid) radical cation deco...
متن کاملTragopogon dubius, Considerations on a Possible Biomimetic Transfer
Tragopogon dubious is a small herbaceous plant that uses the wind as dispersal vector for its seeds. The seeds are attached to stalked parachutes which increase the aerodynamic drag force on the seeds. This decreases their rate of descent, and hence increases the total distance traveled. The relatively large natural parachute of Tragopogon dubious is an ideal model in a biomimetic structure owi...
متن کاملHepatoprotective, Antioxidant, and Anticancer Effects of the Tragopogon porrifolius Methanolic Extract
Tragopogon porrifolius (Asteraceae), commonly referred to as white salsify, is an edible herb used in Lebanese folk medicine to treat cancer and liver dysfunction. In this study, we investigated the antioxidant activity of Tragopogon porrifolius methanolic extract, both in vitro and in vivo, in addition to its hepatoprotective and anticancer activities. Total phenolic and flavonoid contents wer...
متن کاملAnticancer Activity, Antioxidant Activity, and Phenolic and Flavonoids Content of Wild Tragopogon porrifolius Plant Extracts
Tragopogon porrifolius, commonly referred to as white salsify, is an edible herb used in folk medicine to treat cancer. Samples of Tragopogon porrifolius plant grown wild in Palestine were extracted with different solvents: water, 80% ethanol, and 100% ethanol. The extracts were analyzed for their total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity (AA). Four d...
متن کاملOnly seed size matters for germination in different populations of the dimorphic Tragopogon pratensis subsp. pratensis (Asteraceae).
Many studies have focused on the ecology of seed dimorphism, the production of two seed types by a single plant. Morphology and seed size are usually correlated, but how morphology affects germination percentage and seedling growth is poorly understood. Here we explicitly separate these effects for nine populations of the dimorphic species Tragopogon pratensis subsp. pratensis. Larger seeds yie...
