The present study was conducted to investigate the proximate composition, antioxidant properties of sesame seed and chemical characteristics of sesame seed oil. The results showed that the sesame seeds contained 5.19–7.66% moisture, 11.25–19.54% carbohydrate, 19.32–22.81% crude protein, 35.81–49.25% crude fat, 3.23–9.74% crude fibre and 1.50–5.53% ash on dry weight basis. The mineral composition of sesame seeds revealed relatively high amounts of iron (1.34 to 10.01mg/100g), calcium (975.33 to 1282.67 mg/100g), sodium (17.80 to 65.40 mg/100g) and potassium (108.00 to 379.33 mg/100g). Phenolic contents ranged from 0.88 to 1.98 mg catechol equivalent/g, flavonoids content from 0.11 to 0.19 mg quercetin equivalent/g and DPPH inhibition percentage from 59.30 to 67.75%. The iodine value, saponification value and acid value were found in the range of 81.64 to 113.79 g I2/100g oil, 159.89 to 206.64 mg KOH/g oil and 0.56 to 2.16 mg KOH/g oil, respectively.
