PHYTOCHEMICAL AND BIOLOGICAL STUDIES ON PLANT-DERIVED PHENOLIC COMPOUNDS BELONG TO THE FAMILY POLYGONACEAE
polygonum equiseti fomu, aerial parts, new flavonoid, antioxidant activity
Family polygonaceae comprises about 40 genera and 800 species. They exist as herbs, shrubs or trees distributed throughout the world especially in temperate and warm regions. Polygonum is the largest genus belonging to the family polygonaceae. The genus polygonum (polygonaceae), which comprises about 300 species, is distributed worldwide in temperate climates. According to only six species are found in Egypt P. arenastrum, P. avicular, P. bellardii, P. equisetiforme, P. marititimn and p. plebeium. Among these species we selected the species P. equisetiforme for this study. The secondary metabolites identified in the species of the Polygonum genus are flavonoids, Phenolic acids, anthraquinones, lignan glycosides, polysaccharides, phenylpropanoide glycosides, sesquiterpene and stilbenes. Numerous polygonum species are frequently used in traditional medicine. Some species are useful in treatment of cough, diarrhea, diuretic agent and to treat urinaryinflammation.
