摘要：The purpose of this study was to evaluate the amounts of phenolics, flavonoids, and tannins, and to determine the antioxidant and antibacterial activities of aqueous, acetone, methanol, and ethanol extracts of stems and leaves of Chrozaphora tinctoria L. from Zabol, Iran. After collection and extraction of C. tinctoria leaves and stems, the total phenolic, flavonoid, and tannin concentrations were determined spectrophotometrically. The antioxidant activity was determined using 1,1-diphenyl-2-picrylhydrazyl radical-scavenging assay, iron-reducing-power assay, β-carotene-bleaching assay, and antioxidant-capacity assay. Antibacterial activity was determined using disc diffusion assay. The results of this study indicated that C. tinctoria leaf extracts had higher antioxidant activity than in stem extracts. Methanol and acetone extracts had greater antioxidant and antibacterial activity than aqueous extracts. C. tinctoria has antiradical and antimicrobial activity that may be useful in pharmacy and phytotherapy
