Natural and synthetic phenolic compounds belonging to the classes of flavones, coumarins, xanthones, chalcones. isotlavones and desoxybenzoins have been prepared or isolated from plant species, characterized and tested against a battery of 10 pathogenic bacteria, 1 yeast, 3 fungi and 3 viruses. Only two of the compounds show some moderate bacteriostatic activity against gram-positive cocci, but are like all other products inactive against gram-negative bacteria, yeasts and fungi. On the contrary, two flavones, one desoxybenzoin and one diacetoxycoumarin exhibited pronounced antiviral properties against some of the viruses tested. Five other coumarin analogs possessed moderate anti-poliomyelitis properties and one xanthone is to a lesser extent active against Vesicular stomatitis virus. Of the compounds synthesized nine are new compounds.

The fragmentation patterns of closely related chalcones, cinnamoylchromans and cinnamoylchromenes, are reported to be strikingly different.The mass spectra of the first group show peaks typical of the fragmentation of simple chalcones balanced by addition
13C Nuclear Magnetic Resonance Studies on Pyrano- and Dihydropyrano-1,3-diphenylprop-2-enones

The 13C NMR spectra of 19 differently substituted pyrano- and dihydropyrano-1,3-diphenylprop-2-enones were recorded and the results are discussed.The data will be useful in the identification of new and natural chalcones. Key Words: Chalcones - 1,3-Diphen
