Indian amaranth (Amaranthus hypochondriacus L.) is a plant species of complex composition. It contains proteins, carbohydrates, vitamins, fats, cellulose, mineral matters, organic acids, etc. In this work, there were investigated seed of amaranth cultivated in Yugoslavia. The investigations have primarily been concerned with the determination of the contents of proteins (amino acids), fatty oil (fatty acids), and mineral matters. It has been that the investigated samples contain about 20% of crude proteins (%N x 6.25) with the portion of essential amino acids of about 35%, whereby the lysine content amounts even to 5% (5 g / 100g protein). Also, it has been found that the investigated amaranth seeds contain about 7% of fatty oil, and this consists of palmitic (19.7%), stearic (2.93%), oleic (17.75%), linolic (54%) and linoleic acid (1.15%). The analysis of mineral composition showed the investigated plant seeds contain relatively high concentrations of calcium (0.4%), magnesium (0.67%), and potassium (1.15%).
