Phytochemical characterization and antioxidant potential of medicinal plants in the management of chronic inflammatory disorders

Chronic inflammatory disorders, including rheumatoid arthritis, inflammatory bowel disease, cardiovascular complications, and neurodegenerative conditions, represent a significant global health burden due to their multifactorial etiology and progressive pathology. Conventional therapies such as corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs), and biologics provide symptomatic relief but are often associated with adverse effects, drug resistance, and economic burden. In recent years, medicinal plants have emerged as promising therapeutic alternatives owing to their rich reservoir of phytochemicals with antioxidant, anti-inflammatory, and immunomodulatory properties. This study aims to provide a comprehensive evaluation of the phytochemical constituents and antioxidant potential of selected medicinal plants traditionally employed in the management of chronic inflammatory disorders. The methodology integrates qualitative and quantitative phytochemical screening, high-performance liquid chromatography (HPLC), gas chromatography–mass spectrometry (GC-MS), and spectrophotometric assays such as DPPH, FRAP, and ABTS for antioxidant activity. Results highlight the presence of phenolic acids, flavonoids, alkaloids, terpenoids, saponins, and tannins, which contribute to the free radical scavenging capacity and modulation of oxidative stress pathways. Comparative analysis with existing studies underscores the therapeutic relevance of compounds such as quercetin, curcumin, resveratrol, and catechins in attenuating inflammatory cascades by inhibiting NF-κB, COX-2, and iNOS expression. The findings demonstrate that phytochemicals not only mitigate oxidative damage but also regulate cellular signaling, thereby offering a holistic approach to managing chronic inflammatory disorders. The discussion emphasizes the translational potential of plant-derived antioxidants in drug development, while also identifying knowledge gaps in standardization, bioavailability, and clinical validation. The study concludes that phytochemical characterization, coupled with robust antioxidant assays, provides a scientific foundation for integrating medicinal plants into evidence-based management of chronic inflammatory conditions.
