The bioactive potential of three different Rumex species: Antioxidant capacity, mineral composition and elemental status
Rumex L. species have long been recognized not only for their medicinal properties but also as valuable dietary components, owing to the presence of bioactive compounds that support both health and nutrition. This study evaluated the antioxidant capacity, phenolic composition, mineral content, and elemental status in the leaves and flowers of R. alpinus, R. obtusifolius L. subsp. subalpinus, and R. tuberosus L. subsp. horizontalis. Antioxidant activities were determined by FRAP, CUPRAC, and DPPH assays. Phenolic composition (25 phenolic compounds) was determined by HPLC-DAD (high-performance liquid chromatography with diode-array detection). Macro and micro-nutrients were quantified through ICP-MS (inductively coupled plasma mass spectrometry), while the elemental status (C, H, N, S, and O) of methanolic extracts was measured by a CHNS-O analyzer. Notably, the flowers of R. alpinus exhibited the highest FRAP (138.62 µmol Fe/g) and CUPRAC (0.44 mmol TEAC/g) values, along with the strongest DPPH radical scavenging capacity (IC₅₀: 0.15 mg/mL), whereas the leaves of this species showed the highest ascorbic acid content. The total phenolic content reached its peak (64.34 mg g⁻¹) in R. alpinus flowers, while the highest total flavonoid level (17.7 mg g⁻¹) was detected in R. alpinus leaves. Among hydroxybenzoic acids, 3,4-hydroxybenzoic acid (6336 mg kg⁻¹) was predominant in R. alpinus leaves, and progallol (1553 mg kg⁻¹) prevailed in R. tuberosus L. subsp. horizontalis. The flowers of R. alpinus contained the highest oleuropein (4289 mg kg⁻¹), whereas total hydroxycinnamic acids (3534 mg kg⁻¹) were most abundant in R. tuberosus L. subsp. horizontalis. Furthermore, catechin (3667 mg kg⁻¹) was identified as the main flavonoid in the leaves of R. obtusifolius L. subsp. subalpinus. R. alpinus leaves had the greatest Mn (877.6 µg kg⁻¹) and Fe (287.5 µg kg⁻¹) levels, while R. alpinus flowers were richest in Cu (817.8 µg kg⁻¹). The flowers of R. tuberosus L. subsp. horizontalis contained the highest Zn (856.4 µg kg⁻¹). Additionally, R. tuberosus L. subsp. horizontalis leaves showed notable Mg (594 mg 100 g⁻¹) and K (4320 mg 100 g⁻¹) contents, and high Ca (1019 mg 100 g⁻¹) was detected in both its leaves and flowers. Elemental analysis further indicated that R. alpinus flowers had the highest carbon content (46 %), whereas R. tuberosus L. subsp. horizontalis flowers exhibited the highest hydrogen level (6 %). In light of these results, R. alpinus, R. obtusifolius subsp. subalpinus, and R. tuberosus subsp. horizontalis not only offer potential nutritional and pharmacological benefits but also exhibit distinct chemotaxonomic characteristics. This study provides a comprehensive scientific framework that integrates phytochemical, elemental, and antioxidant properties, supporting the taxonomic differentiation of Rumex species while expanding their potential applications in functional foods and medicine.
