As the therapeutic potential of <em>G. hederacea</em> is related to the presence of phenolic compounds, the study on qualitative and quantitative analysis of phenolics by HPLC method was performed. The analysis revealed significant differences in the quality of ground ivy plant material, in terms of the content of bioactive compounds. The determined levels of rosmarinic acid, chlorogenic acid, gallic acid and rutin in the products ranged from 0.10 to 4.55 mg/g DW; 0.18–1.57 mg/g DW; 0.02–1.28 mg/g DW; to 6.01 mg/g DW, respectively. Additionally, the products varied significantly in the sum of determined polyphenols (1.5 – 7.16 mg/g DW). The findings highlight the need to establish the standards and requirements for bioactive phenolic content to ensure high-quality plant material with significant medicinal value.
