Abstract

Curcuma longa (Turmeric, Haldi) is an important medicinal and traditional plant belonging to the family Zinger beraceae. Current studies were performed to explore the phytochemical composition, nutritional value, antioxidant and antimicrobial potential of Curcuma longa rhizome collected from Pattoki (Kasur), Pakistan. Phytochemical investigations have shown the presence of secondary metabolites such as saponins, terpenoids, glycosides, tannins, and alkaloids. The extract displayed fantastic antioxidant potential with 70.34% total phenolic content (TPC). The highest antioxidant potential 87.92% was observed with a 50μg/mL concentration of methanolic extract. The plant extract has shown an excellent nutritional potential due to the presence of significant quantities of carbohydrates, protein, fibers, fat, and energy content of 101.12 Kcal/100g. However, it displayed insignificant antimicrobial potential against tested bacterial (Staphylococcus aureus, Bacillus subtilis, Salmonella typhi, and Escherichia coli) and fungal (Fusarium oxysporum, Aspergillus niger, Aspergillus flavus, and Alteraria alternata) strains.
