ANTIMICROBIAL ACTIVITY AND PHYTOCHEMICAL ANALYSIS OF INDIGOFERA TINCTORIA

Indigofera tinctoria, named true indigo in English, is a leguminous plant displaying a vast traditional and modern medicinal uses. Historical importance, phytochemistry, pharmacological properties, and possible applications of the indigo plant are the major points of discussion in this review. Rich in several bioactive compounds such as flavonoids, alkaloids, saponins, tannins, and phenolics, these together exhibit antimicrobial, antioxidant, anti-inflammatory, and hepatoprotective activities. Antibacterial studies authenticate its potency against several pathogenic strains such as Staphylococcus aureus, Escherichia coli, and Salmonella typhi; antifungal and antiviral potentials are under investigation. It also acts as a sustainable source of natural dye useful for textile industries while offering ecological benefits, such as soil enrichment through nitrogen fixation. Clinical trials and standardized extraction protocols remain limited, even with promising results in vitro and some novel applications in green nanoparticle synthesis. Further research is recommended to fully authenticate the pharmacological applications of Indigofera tinctoria and widen its application in sustainable health and environmental management.
