Figure 10: 1,1-Diphenyl-2-picrylhydrazyl free radical scavenging activity of (a). 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid standard (3.12-100 μg/ml) (b). Saraca asoca extract and Microparticles (Chitosan: Polyethylene glycol [2.1:0.9], Drug [18.13%], sodium tripolyphosphate [6.9%] and crosslinking time [34.44 min]). Box-plot showing mean values of the IC50 values with each different alphabet showing statistical difference at P ≤ 0.05
