  This study presents the mineral composition of leaves and pods of Moringa oleifera from different agro climatic regions of Punjab. Samples of leaves and pods were wet digested and analyzed for various minerals by using Atomic Absorption Spectrophotometer (AAS) and flame photometer. The contents K, Ca, Mg, Na in the leaves and pods of Moringa oleifera was found to be 19732-24397, 1839-2097; 18950-26349, 1292-1837; 98.2-109, 93.9-103.9 and 1635-2721, 1032-2105 mg kg-1 respectively. The concentration of Fe, Cu, Mn and Zn was found to be 205-573, 155.2-435.9; 7.3-11.2, 20.9-32.1; 76.9-112.8, 40.2-72 and 20.9-34.1, 15.3-29 mg kg-1 respectively. The level of P in the samples of leaves and pods was 1180-1450 and 1860-2125 mg kg-1 respectively. The contents of different minerals in the leaves and pods of M. oleifera were significantly varied from region to region. The results of present analysis revealed that pods and leaves of M. oleifera indigenous to different agro-climatic regions of Punjab contained a considerably high amount of Ca, Mg, K, Mn, P, Zn, Na, Cu and Fe and might be used as a viable supplement of dietary minerals.

  The present study was aimed to evaluate the antioxidant activity of different solvent extracts of Moringa oleifera leaves by using accelerated aging of sunflower oil. Methanolic and acetone (80 and 100%) extracts of M. oleifera leaves were added at the concentration of 0.06% (wt/wt) into the refined, bleached and deodorized sunflower oil. The stabilized sunflower oil samples were subjected to accelerated aging (65°C) for a period of 18 days and analysis was done periodically after every three days. The extent of oxidation was followed by the measurement of AI-, PV-, conjugated dienes-, trienes- and para-anisidine values. The overall order of antioxidant efficacy of the extracts of M. oleifera leaves as assessed by various oxidation parameters was followed as; 80% methanolic extract > 100% methanolic extract > 80% acetone extract > 100% acetone extract. The antioxidant activity of M. oleifera leaves might be attributed to the presence of high amount of flavonoids, polyphenolics and tocopherol contents. The results of present study revealed that M. oleifera leaves might be explored as a viable source of natural antioxidants and nutraceuticals.
