Table 2 Effect of salinity stress on total phenols, flavonoids, tannins, saponins, alkaloids, total antioxidant capacity (TAC) contents, and DPPH% on methanolic and water extracts of M. longifolia L. plant exposed to salinity for 2 months. Results are shown as a mean of three replicates ± SE. The values with the same letter in the same column are non-significant and with different letters are significant.
