Abstract Cinnamomum zeylanicumBlume, known for its medicinal and culinary value, was analyzed for comparative phytochemical profiling and antioxidant potential between Indian (Shillong, Kolkata) and African (Tanzania) stem bark varieties. Using HPTLC and GC-MS, the essential oils revealed key variations in chemical constituents, notably the exclusive presence of eugenol in the Tanzanian variety and higher cinnamaldehyde dimethyl acetal content. Physicochemical and organoleptic differences reflected geographic influence. Antioxidant studies using DPPH and FRAP assays confirmed superior activity in the Tanzanian sample, with the lowest IC50 (22.05 µg/ml) and highest FRAP value (579 µM). Phytochemical screening confirmed the presence of multiple bioactive compounds in the samples. These results underscore the significance of geographical origin in the quality and efficacy of medicinal plants, supporting the need for standardization protocols. This study provides a robust framework for evaluating regional variations in C. zeylanicum, enhancing its pharmacological validation and ensuring authenticity in herbal formulations. Molecular docking study with Eugenol revealed strong binding affinity of eugenol with protein targets iNOS, PPARδ, and PPARα in diabetes, and with acetylcholinesterase in Alzheimer’s disease.
