Synthesis, Characterization and Antimicrobial activity of Some Flavones

Flavonoids are ubiquitous in photo synthesizing cells and are commonly found in fruit, vegetables, nuts, seeds, stems, flowers, tea, wine, propolis and honey. For centuries, preparations containing these compounds as the principle physiologically active constituents have been used to treat human diseases. These are abundant in polygonaceae, rutaceae, leguminosae, umbelliferae and compositae. 2 (subtituted phenyl) – 4H-Chromen – 4 – one's were synthesized from substituted chalcones. The compounds obtained were identified by spectral data and screened for antimicrobial activity.
