Abstract:

This study investigates the total phenolic and flavonoid contents, antioxidant activity, and metal chelation capacity of acetone and water extracts from Anethum graveolens L.. The total phenolic content of the acetone extract was significantly higher (173.49 ± 4.91 µg GAE/mg extract) than the water extract (98.52 ± 3.62 µg GAE/mg extract). Similarly, the flavonoid content of the acetone extract (72.81 ± 1.15 µg QE/mg extract) exceeded that of the water extract (27.69 ± 1.72 µg QE/mg extract). Concentration-dependent responses revealed higher antioxidant activity for the acetone extract across

A high extraction yield (67–60% solubilized solids) was achieved, and the extracts contained high levels of total phenols (51–73 mg GAE·g−1 extract) and betalains and great radical scavenging ca

Background: Sugar kelp (Saccharina latissima, formerly known as Laminaria saccharina) is a brown seaweed which naturally occurs in the North Atlantic. Seaweeds may be one of the last natural food resources abundantly available. They are known to contain many compounds which may have additional functional benefits. This edible seaweed is characterized by high content of nutrients including carbohydrates and polyphenols, which are recognized antioxidants. Because their natural environment is a 3% saline solution, they are very resistant to mild extraction methods. However, extracts from solvent
