The iron content obtained by different authors varied. The results they achieved were generally lower than ours [49; 53; 54]. However, our results were within the range specified by some authors [51]. The mean values (19.1 g 100 g\({}^{-1}\) DW) determined by [PERSON], et al. [55] in the leaves of the cultivar _Polana_ from 80 plantations in Lublin, are higher than our findings. Only the leaves of wild-growing raspberry harvested in 2021 had a higher iron content than the aforementioned results. Higher results were also obtained by [PERSON] and [PERSON] [52] for the leaves of raspberry varieties _Glen Ample_, _Laszka_ and _Radziejova_, which were 17.6, 20.8 and 25.2 mg of iron per 100 g DW, respectively.
