The overground organs of 2 female forms of stinging nettle were compared in regard to morphological features, and yield, as well as the content of assimilation dyes, flavonoids, and polyphenolic acids. The examined forms different in the height of the plants, the number of shoots and the size of leaves. The female form A was characterized by the higher mass of herb, leaves and inflorescences. There were no differences between the examined forms in the content of chlorophyll and carotenoids in the leaves. The leaves of the female form B were characterized by the higher content of flavonoids (0.65 percent) and polyphenolic acids (1.46 percent) in comparison with the female form A (0.55 percent and 1.00 percent respectively). The highest amount of polyphenolic acids in both forms were present in inflorescences and the lowest in stems. Female form A was characterized by higher content of scopoletin
