The present study was conducted to determine the proximate, fatty acids, minerals and antioxidants content in chia seeds. The results showed that fat ranged from 28.85-29.53%, protein 18.63-18.71%, moisture 5.27-5.28 %, ash 4.45-4.47 %, total carbohydrate 25.21-27.86 %, fiber 17.35-19.12% and energy obtained 428.11-436.70 kcal/100g. Fatty acid profile indicated the presence of linolenic (56.76-57.65 %), linoleic (20.49-21.47 %), palmitic (9.38-11.34 %) and oleic (7.47-7.99 %) were abundant, while less amount of saturated fatty acids myristic (0.09-0.15 %), lauric (0.11-0.33 %) and stearic (2.52-3.13 %) were found all the tested samples. Mineral content in all the tested samples showed that high amount of calcium (578.62-589.71 mg/100g), potassium (518.95-535.42 mg/100g), phosphorous (668.62-697.61 mg/100g), magnesium (334.24-344.51 mg/100g), iron (7.13-7.56 mg/100g), zinc (4.23-4.57), manganese (2.19-2.95 mg/100g), and copper (1.59 -1.83 mg/100g) were found. The total phenolic (1.71-1.92 mg GAE/g), total flavonoids (1.07-1.16 mg QE/g), DPPH (2,2-diphenyl-1-picrylhydrazyl) (2.51-2.81 mg GAE/g), and Ferric-reducing Antioxidant Power, FRAP (1.86-2.22 mg TE/g) were found in the seeds.
