Abstract: The phenolics and Flavonoids content of six Justicia species were determined in the present study. The phenolic content was determined by using Folin-Ciocalteu assay. The total flavonoids were measured spectrophotometrically by using the aluminum chloride colorimetric assay. The results showed that the different parts of selected Justicia species contain significant amount phenolics and flavonoids. The highest phenolic content was showed by leaf of J. adhatoda (38.75 mg GAE) and the least phenolics were observed for root of J. beddomei (22.65 mg GAE). In the case of flavonoids, maximum value was obtained for leaf of J. betonica (2.86 mg QE) and least flavonoid content was showed by root of J. adhatoda (1.25 mg QE).
