Indigenous leafy vegetables have been recognized as rich sources of natural antioxidants, hence having the power to perform preventive effects in opposition to serious disorders which are related to oxidative stress. They contain trace elements, which are act as dietary constituents and play important role in human system. Present study evaluated the proximate composition and mineral profile, contribution to nutritional significance, and antioxidant potential of two lesser known greens, Achyranthes aspera and Talinum triangulare. Different processing methods are adopted to assess their influence on nutritive value and antioxidant properties. Mineral contents were studied by employing ICP-MS (Inductively Coupled Plasma - Mass Spectrometer). Using different in vitro models, antioxidant potential of raw and processed samples were determined. Compared to raw, processed samples registered better values. Results revealed that cooking has influenced the mineral profile and antioxidant capacity. The presence of essential minerals such as Na, K, Zn and Mn were observed. Current study suggests that lesser known leafy vegetables efficiently contribute to the nutritional requirement and food security.
