The medicinal plants of Achillea millefolium group are largely collected from their natural habitats this leading to both ecological risks and heterogeneity of the collected market samples. Our previous studies supplied evidence that field cultivation of wild species of the group (A. collina and A. asplenifolia) is a promising approach to obtain homogenous plant material without damage to the environment. In these studies inflorescences were the object of field experiments while in the present paper stems and leaves were investigated. The experimental design involved the above mentioned species (each with two populations) the seeds being collected from the natural habitats of plants. Cv. Proa bred for field cultivation was used as a standard; its seeds were purchased from the firm "Pharmasaat GmbH", Germany. The results confirm the findings of our previous work carried out with inflorescences, namely that stems and leaves contain flavonoids above the reference limit of European Pharmacopoeia (3 mg/g). This accounts for the high AO and AR activities as shown by the strong correlation between flavonoids and these items. Moreover, similarly to inflorescences, stems and leaves show low intraspecific variability and larger interspecific differences with regards to all characters studied. This suggests to the species studied being isolated and distant enough to serve as a homogenous source of raw yarrow material for the market. A. asplenifolia is distinguished by a higher potential of valuable components than A. collina while being closer by all parameters to cv. Proa. These data point to A. asplenifolia as a promising species for field cultivation. The weight ratio of plant parts shows that inflorescences dominate followed by stems and leaves.
