Phytochemical Investigation of Rumex olympicus Boiss.: Isolation of Two Catechins and an Anthraquinone

Objective: The genus Rumex is represented by 25 species in the flora of Türkiye and is characterized by the presence of anthranoids, flavonoids, tannins, and naphthalene derivatives. In addition to their use as food, Rumex species are traditionally recognized for their laxative, wound-healing, and diuretic properties. This study aims to investigate the phytochemical constituents of Rumex olympicus Boiss. and to contribute the chemical characterization of the genus.Methods: Within the scope of the study, the roots, leaves, and fruiting inner perianth parts of Rumex olympicus were separately collected and dried. Among these, the fruiting inner perianth parts were selected for phytochemical investigation, and isolation procedures were carried out on the ethyl acetate extract. Results: As a result of the phytochemical investigations, tannin derivatives catechin, epicatechin-3′-O-gallate, and the anthraquinone derivative emodin-8-β-D-glucoside were isolated from the fruiting inner perianth parts of Rumex olympicus Boiss.Conclusion: The findings of this study contribute to the phytochemical profile of Rumex olympicus and support the presence of bioactive secondary metabolites within the genus. These results may provide a scientific basis for further pharmacological studies and potential applications of this endemic species.
