This study investigates the synergistic potential of methanolic extracts from different parts of *Rumex roseus*—roots (RRR), stems (RRS), and leaves (RRL)—in mitigating oxidative stress and inflammation, two interconnected pathological processes underlying chronic diseases such as cardiovascular disorders, neurodegeneration, and inflammatory bowel disease. While individual extracts have been analyzed for their bioactivity, this work focuses on the collective and complementary effects of these plant-derived fractions, highlighting their capacity to act in concert to enhance therapeutic outcomes.
Phytochemical profiling revealed distinct metabolic fingerprints across the three organs. RRL was rich in apigenin and luteolin glycosides, compounds known for their ability to modulate redox-sensitive signaling pathways and inhibit pro-inflammatory mediators. RRS contained a balanced mix of phenolic acids and flavonoids, including p-coumaric acid and ferulic acid, which contribute to radical scavenging and membrane stabilization. RRR, however, stood out due to its high concentration of condensed tannins and quinic acid derivatives such as diCQA and CFQA—molecules with documented anti-oxidative, anti-inflammatory, and protein-protective properties. The presence of multiple compound classes within each extract suggests that the biological effects are not solely attributable to single constituents but arise from complex interactions among various phytochemicals.
In vitro antioxidant assays confirmed that while RRR exhibited the strongest activity in TAC-Pm, TEAC, FRAP, and SOD-like assays, RRL showed exceptional performance in ORAC and HOCl-induced albumin protection. This divergence underscores the importance of assay-specific mechanisms: RRR’s superior reducing power may stem from its tannin content, whereas RRL’s effectiveness in preventing protein oxidation likely results from luteolin and caffeic acid, which readily interact with reactive oxygen species and stabilize macromolecules. Notably, when combined, the extracts demonstrated additive or even synergistic effects in certain assays, indicating that mixing components from different plant parts could amplify overall bioactivity beyond what is observed individually.
The anti-inflammatory evaluation using TNF-α-stimulated Caco-2 cells further supported this synergy. Pretreatment with RRR and RRS significantly suppressed TNF-α-induced upregulation of IL-6 and IL-8 mRNA expression in a dose-dependent manner, confirming their ability to interfere with NF-κB activation. However, RRL failed to show significant activity under the same conditions, possibly due to cytotoxicity at higher concentrations or the inability of certain flavonoids to penetrate cellular targets effectively. Despite this limitation, the combination of RRR and RRL may offer a more comprehensive approach: RRR provides systemic antioxidant and NF-κB inhibitory effects, while RRL contributes targeted protein protection and modulation of immune responses.SF3A3 Antibody Autophagy
Moreover, biocompatibility testing revealed that RRR and RRS were safe at all tested concentrations (up to 70 µg/mL), whereas RRL induced cytotoxicity at the highest dose.Raf-B Antibody Biological Activity This safety profile supports the use of root and stem extracts in formulations requiring prolonged exposure.PMID:35116025 The absence of toxicity in RRR, despite its high polyphenol load, suggests that its tannin structure may confer favorable bioavailability and low cellular toxicity compared to other polyphenols.
These findings suggest that the full therapeutic potential of *Rumex roseus* lies not in isolating single fractions but in harnessing the natural synergy between its organ-specific metabolites. A formulation combining RRR and RRS could deliver potent antioxidant and anti-inflammatory action, while inclusion of RRL might enhance protection against protein damage. Such an integrative strategy aligns with traditional herbal medicine practices, where whole-plant preparations are preferred over isolated compounds.
In conclusion, this study demonstrates that the methanolic extracts of *Rumex roseus* possess complementary and potentially synergistic bioactivities. Their combined use offers a promising avenue for developing effective, multi-targeted nutraceuticals and phytopharmaceuticals aimed at preventing and managing diseases driven by oxidative stress and chronic inflammation.MedChemExpress (MCE) offers a wide range of high-quality research chemicals and biochemicals (novel life-science reagents, reference compounds and natural compounds) for scientific use.
