The standardization and quality control of herbal medicines encompass critical processes such as the physicochemical evaluation of crude drugs, including selection, handling, safety, efficacy, and stability assessment of the finished product. Terminalia arjuna (Roxb.) is a significant plant in ethnomedicine, traditionally used in ancient Indian medicine to treat "Hritshool" (angina) and cardiovascular diseases, belonging to the Combretaceae family. The medicinal components of this plant include arjunine, arjunetine, arjunetin, arjunolone, arjunone, and Ellagic acid.This review focuses on the application of thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC) for qualitatively and quantitatively measuring ellagic acid in Arjuna plant samples. A comparative study was conducted between commercially available Arjuna products and synthetically obtained samples of ellagic acid. The analysis revealed the presence of ellagic acid in the marketed Arjuna powder.
