Search for: [Abstract = "nd made it possible to measure the antioxidative activity in seeds and sprouts of amaranth and quinoa. In\-vitro testing also led to significant improvement in the methods of sprouts cultivation and allowed for finding the optimal tillage conditions \(depending on the amount of light\) and its length so that sprouts with the highest antioxidant contents can be cultivated. Comparision of the antioxidative activity suggests that antioxidants in quinoa and amaranth differ both in quality and quantity. Quinoa seeds were higher in fast\-acting antioxidants \(much better results by DPPH were observed for quinoa than amaranth\) such as e.g. polyphenols, whose total contents in quinoa were higher than in other seeds. It has also been confirmed by the positive correlation between the total contents of polyphenols in investigated seeds and their antioxidative activity. Contrary to seeds, amaranth sprouts had higher antioxidative activity than quinoa sprouts – a result confirmed by all analytical methods employed. Tests by DPPH showed the greatest differences, which may indicate that amaranth sprouts contained new, fast\-acting antioxidative substances other than polyphenols, as their total content was still higher in amaranth sprouts. In amaranth sprouts, especially in amaranth v. Aztek, the level of anthocyanins increased significantly. The synthesis of antioxidants in sprouts \(such as e."]
