SC₅₀, Half scavenging concentration (amount required to reduce the initial oxidant concentration by 50%) calculated in µg/mg of the dry extract or standard/mL of the reaction mixture; ** inactive up to a concentration of 500 µg/mL; *** inactive up to 1500 µg/mL. For extracts codes, see Abbreviations. Data are given as mean of three replicates ± SD. Values in each column labeled with different capital letters (A–K) are significantly different at p < 0.05.
