Abstract
Five flavones dioxygenated at C-2'' and 6'' (5, 7, 2'', 6''-tetrahydroxy-, 5, 7, 2''-trihydroxy-6''-methoxy-, 5,2''-dihydroxy-7, 8, 6''-trimethoxy-, 5, 2'', 6''-trihydroxy-7, 8-dimethoxy-, and 5, 7, 2''-trihydroxy-8, 6''-dimethoxyflavone) isolated from Scutellaria spp. were synthesized to confirm their structures. Spectroscopic comparisons of the synthetics with the corresponding natural flavones confirmed the respective structures.Keywords
