2,3,10-Trimethoxy-5-phenyl-5,6-dihydro-7H-benzoxanthene-7-one (V) and 2,3,8,10-tetramethoxy-5-phenyl-5,6-dihydro-7H-benzoxanthene-7-one (XVI) have been obtained by photocyclization of appropriate 3-substituted flavone derivatives.

In addition to sitosterol glucoside and 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 methyl ethers of the natural aglycones.Key Word - Eugenia kurzii; Myrtaceae; flavonoids; 3-C-methylapigenin 5-O-rhamnoside; 3-C-methylluteolin 5-O-rhamnoside
