Non – Conventional Seeds are being considered in the study due to their sole chemical compositions and functional properties. Black cumin seeds, frequently known as Black Seeds or Kalojeera in Bengali, are conventionally used for nutritional and medicinal purposes in Middle, Eastern and Western countries.The core objective of this analysis was to assess the foremost nutrients of Bangladeshi black cumin seeds and depiction of its oil. The proximate analysis indicated the seeds as a fibrous food containing pH 5.63 and also a good source of carbohydrate, protein, and lipid that were found subsequently in the amount of 29.18, 18.09 and 32.74 gm%. Its mineral content is also calculated to be rich where Calcium (Ca), Potassium (K), Magnesium (Mg), Sodium (Na), Phosphorus (P) and Iron (Fe) were determined at the amount of 579.33, 510.30, 218.33, 100, 91.5 and 41.80 mg/100gm, respectively. Screening for secondary metabolites showed the presence of alkaloids, flavonoids, saponins and tannins at the amount of 10.11, 3.78, 7.58 and 2.21 mg/100gm consequently. Primary characterization of seeds extracts oil indicated it as a good source of polyunsaturated fatty acids.
