Antibacterial activity of flavonoid extracts from and against multidrug-resistant foodborne bacterial isolates.

Background: Food poisoning caused by bacterial agents is a worldwide problem, usually accompanied by unpleasant symptoms and may be severe leading to death. Natural compounds from marine algae namely flavonoids may play a role in the remedy of this condition.

Aim: This research aims to assess the potency of flavonoids extracted from and as antibacterial agents.

Evaluation of Antidiabetic Effect of Combined Leaf and Seed Extracts of () on Alloxan-Induced Diabetes in Mice: A Biochemical and Histological Study.

() is a medicinal plant rich in biologically active compounds. The aim of the present study was to screen methanolic leaf (L) extract, seed (S) extract, and a combined leaf/seed extract (2L : 1S ratio) for antidiabetic and antioxidant activities in mice following administration at a dose level of 500 mg/kg of body weight/day. Diabetes was induced by alloxan administration.

Nutritional and Nonnutritional Content of Underexploited Edible Seaweeds.

Macroalgae are a valuable source of highly bioactive primary and secondary metabolites that may have useful bioapplications. To investigate the nutritional and nonnutritional contents of underexploited edible seaweeds, proximate composition, including protein, fat, ash, vitamins A, C, and E, and niacin, as well as important phytochemicals, including polyphenols, tannins, flavonoids, alkaloids, sterols, saponins, and coumarins, were screened from algal species using spectrophotometric methods. Ash content ranged from 3.
