Total phenolic content (μg GAE/mg DW), total flavonoid content (μg QE/mg DW), total reducing power (μg AAE/mg DW), total antioxidant capacity (μg AAE/mg DW) and free radical scavenging activity (%) of A. bracteosa in different extracts. IC50 of ascorbic acid is found to be 21.8 μg/ml. Values are presented as mean ± Standard deviation (n = 3). The columns with different superscript (a-g) letters show significantly (P < 0.05) different means
