ABSTRACT. Investigation of the aerial parts of Dorstenia ciliata yielded two new prenylated flavones named ciliatins A and B and characterized as 6,7-(2’’-isopropenyldihydrofurano)-5,4’-dihydroxyflavone and 6,5-(2,2-dimethyldihydropyrano)-7,4’-dihydroxy-3’-methoxyflavone, respectively. Known flavonoids: stipulin, isobavachalcone, licoflavone C, 6-prenylapigenin, dinklagin C, gancaonin P, canniflavone and poinsettifolin A were also identified. Structures of these secondary metabolites were established on the basis of spectroscopic analysis, comparison with published information and with authentic specimen for some cases and chemical evidence for the dihydropyranoflavone derivative.
