This study has attempted to compare the total antioxidant capacity of methanol extracts of these three plants using DPPH (1,1-Diphenyl-2-Picrylhydrazyl) radical scavenging assay in which spectrophotometry method was used at 517 nm. The results showed that the aerial parts (AP) of A. sieberi has the highest total antioxidant capacity (IC50=11.054 mg/mL). The lowest amount of antioxidant capacity was found in the root (R) of A. aucheri (IC50= 91.408 mg/mL). https://icc.journals.pnu.ac.ir/article_991_aaf6308bfe8e5b6d00a897fcb8c6461b.pdf
