Cytisus scoparius link - A natural antioxidant
BACKGROUND Recent investigations have shown that the antioxidant properties of plants could be correlated with oxidative stress defense and different human diseases. In this respect flavonoids and other polyphenolic compounds have gained the greatest attention. The plant Cytisus scoparius contains the main constituent of flavone and flavonals. The present study was undertaken to evaluate the in...
متن کاملTwo Flavones from Salvia leriaefolia
The methanolic extract of the aerial parts of Salvia leriaefolia (labiatae) afforded 5-hydroxy-4´, 6, 7-trimethoxy flavone (Salvigenin) and (5,4´-dihydroxy-7-methoxy flavone (Genkwanin). The structures of the isolated compounds were elucidated using 1 and 2 D-NMR, IR, UV and MS.
متن کاملPatterns of Growth Costs and Nitrogen Acquisition in Cytisus striatus (Hill) Rothm. and Cytisus balansae (Boiss.) Ball are Mediated by Sources of Inorganic N
Nitrogen-fixing shrubby legumes in the Mediterranean area partly overcome nutrient limitations by making use of soil N and atmospheric N₂ sources. Their ability to switch between different sources lets them adjust to the carbon costs pertaining to N acquisition throughout the year. We investigated the utilization of different inorganic N sources by Cytisus balansae and Cytisus striatus, shrubby...

متن کاملFlavones: From Biosynthesis to Health Benefits
Flavones correspond to a flavonoid subgroup that is widely distributed in the plants, and which can be synthesized by different pathways, depending on whether they contain C- or O-glycosylation and hydroxylated B-ring. Flavones are emerging as very important specialized metabolites involved in plant signaling and defense, as well as key ingredients of the human diet, with significant health ben...
