The present study was done on the evaluation and quatification of Flavonoids in the barks of selected taxa of Combretaceae viz. Terminalia (Terminalia alata, Terminalia arjuna, Terminalia bellirica, Terminalia catappa, Terminalia chebula, Terminalia pallida, Terminalia paniculata), Anogeissus acuminata, Anogeissus latifolia, Calycopteris floribunda, Combretum albidum and Quisqualis indica The selected species such as was randomly selected for the research and the quantitation of flavonoids were detected and identified by paper chromatography technique (R f values) and standard methodology. The total flavonoid contents (TFC) varied from 77.94 to 238 mg/g, expressed as Rutin equivalents. We conclude that all the selected taxa Barks of Combretaceae possess and can be regarded as promising candidates for natural plant sources high value dietary rich flavonoids.
