The seeds and aerial parts of Trigonella monspeliaca were analyzed by ICP-MS to determine mineral composition. K, P, Ca and Mg were main minerals in the seeds. Ca, K and P were the major elements in the aerial parts. Total phenol and flavonoid content of the aqueous methanol extracts of the plant was measured by Folin-Ciocalteu and the AlCl3 assay, respectively. Antioxidant potential of the extracts was evaluated by free radical scavenging activity using DPPH assay. The present study showed that the seed extract contained significantly higher amount of total phenolics (150.80±0.33 mg GAE/g) while aerial parts had high amount of total flavonoids. In DPPH radical scaven-ging assay, inhibition % of the extracts was found to be 51.6-78.0.
