The objective of this study was to examine differences in antioxidants content: phytate, phenolics, free thiolics (PSH) and glutathione (GSH) in seeds of 7 soybean varieties and 10 sunflower lines with the aim to signify their nutritive quality, valuable for further breeding process. The variations between soybean varieties in phytate content were minor, while el/7 was sunflower line with lowest phytate content, which could be used for program of low phytate grain. The relative high phytate and phenolics content was present in Laura seeds, as well as lowest PSH and GSH content. Generally, the higher content of phenolics were in sunflower seeds, what could be considered as negative atribut from nutritive point of view. The highest PSH content was observed in soybean seeds of Nena and Olga. Lower PSH and GSH content was noted in sunflower seeds (down to 4 and 7 times, respectively), compared to soybean. The soybean seeds have potentially better antioxidative potential, compared to sunflower, owing to multiple higher PSH and GSH content and lower level of phenolics. Soybean variety Olga is accenuated as high in PSH and GSH, as well as sunflower line 14/ru, which had higher PSH and particularly GSH level, with lower phytate and phenolics content, as possible antinutrients.
