gallic acid, two new flavone glycosides have been isolated from Eugenia kurzii (aerial parts) and characterized as 3- C -methylapigenin 5- O -rhamnoside and 3- C -methylluteolin 5- O -rhamnoside by spectral analysis and chemical conversion. 7,4′-Dimethyl-3- C -methylapigenin and 7,3′,4′-trimethyl-3- C -methylluteolin were synthesized by modified Baker—Venkataraman transformations and compared with the
