Comparison of the Nutritive Value, Antioxidant and Antibacterial Activities of Sonchus asper and Sonchus oleraceus
Many local vegetable materials are under-exploited because of inadequate scientific knowledge of their nutritional potentials. For this reason, the nutritional, phytochemical, antioxidant and antibacterial activities of the acetone, methanol and water extracts of the leaves of Sonchus asper and Sonchus oleraceus were investigated. The proximate analysis showed that the plants contained apprecia...
متن کاملEvaluation of the Chemical Composition of Sonchus eruca and Sonchus asper
Sonchus eruca and Sonchus asper were analyzed for their chemical evaluation, vitamins and bioactive secondary metabolite. The results revealed the presence of bioactive constituents comprising alkaloids (1.24 to 1.34 mg/100 g), saponins (1.46 to 1.72 mg/100 g), flavonoids (1.61 to 1.34mg/100 g), phenols (1.32 to1.44 mg/100g), saponins (0.12 to 0.41mg/100 g) and tannins (0.02 to 0.61 mg/100g). T...
متن کاملThe antioxidant and cytotoxic activities of Sonchus oleraceus L. extracts
This study investigated in vitro antioxidant activity of Sonchus oleraceus L. by extraction solvent, which were examined by reducing power, hydroxyl radical-scavenging activity(HRSA) and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assays. 70% MeOH extract had the greatest reducing power while EtOH extract had the greatest HRSA. The antioxidant activity of S. oleraceus extracts was ...
متن کاملAntioxidant and antidiabetic profiles of two African medicinal plants: Picralima nitida (Apocynaceae) and Sonchus oleraceus (Asteraceae)
BACKGROUND Diabetes mellitus (DM) is a metabolic disease characterized by chronic hyperglycaemia generally associated with oxidative stress. The present study aims at evaluating the antioxidant and antidiabetic potential of methanol and hydroethanol extracts of the stem bark and leaves of Pricralima nitida and the Sonchus oleraceus whole plant respectively. METHODS The in vitro antioxidant ac...
متن کاملEvaluation of phenolic contents and antioxidant activity of various solvent extracts of Sonchus asper (L.) Hill
BACKGROUND Sonchus asper (SA) is traditionally used for the treatment of various ailments associated with liver, lungs and kidneys. This study was aimed to investigate the therapeutic potential of nonpolar (hexane, SAHE; ethyl acetate, SAEE and chloroform, SACE) and polar (methanol, SAME) crude extracts of the whole plant. METHODS To achieve these goals, several parameters including free-radi...
