Abstract
family Poaceae growing in Egypt. Phragmites communis, also known as P. australis or the common reed, is a tall, perennial helophyte with a large network of robust underground rhizomes that belongs to the family Poaceae. This plant is an invasive grass that occupies the banks of rivers, ponds, lakes, and swamps, and contributes to the ecological balance and species diversity of such aquatic environments. It also provides a range of other ecosystem contributions, such as habitat, climate regulation, carbon sequestration, and water quality management. Besides its ecological importance, it possesses a significant folk medicine reputation. Phytochemical analysis of P. communis plants has recently yielded a number of important phytocompounds. Biologically, it has been reported that P. communis possesses outstanding antioxidant, anti-inflammatory, hepatoprotective, hypoglycemic, hypolipidemic, anticancer, antimicrobial, and immunostimulant properties with high safety margins. The current study of P. communis rhizomes included:
Part I:
Phytochemical study of P. communis including extraction, fractionation, isolation, and identification of several constituents from the rhizomes of P. communis.
Part II:
Biological study of. P. communis rhizomes including evaluation of total phenolic and flavonoid contents, antioxidant, cytotoxic, anti-inflammatory, and anti-Parkinson’s activities of their different extracts.
