Table 2.

Mean ratio (%) of total phenolic acids and flavonoids in plant organs of Achillea millefolium from Turkish and Lithuanian populations. Significant differences (p₁) between compound groups according to the Wilcoxon matched pairs test and differences (p₂) between countries according to Kruskal–Wallis test.

Plant Organ	Turkey		p 1	Lithuania		p 1	Acids	Flavonoids
