Table 2. The comparative DPPH activity of beta-sitosterol and ascorbic acid (STANDARD).

The different concentration levels are depicted with the percentage of inhibition of DPPH activity of beta-sitosterol and ascorbic acid (STANDARD). Each value signifies the mean ± standard error of the mean (SEM).
