Phytochemical analysis on Stachys alpina L. different organs collected in Poland

The purpose of this study was to determine the phytochemical composition of different organs of Stachys alpina L. collected in Poland, in light of the significant lack of data available in the literature. In particular, roots, stems, leaves and flowers of this species were collected around the town of Szczytna and extracted by alcoholic maceration. Four molecules–namely verbascoside (1), harpagide (2), melittoside (3) and chlorogenic acid (4)–were identified from these extracts by comparing their spectroscopic data with those reported in the literature. Some of these were found in common but none of them was reported in all the studied organs. In addition, during this study, for the first time, verbascoside (1) was identified in the species whereas harpagide (2) in the roots of this species. The chemophenetic significance of these findings is discussed in detail.
