Purslane (Portulaca oleracea L.) is a highly efficient drought- and salinity-tolerant plant species that grows in hostile environmental conditions in many countries [1], [2] and [3]. Differences in varieties, harvesting times, and environmental conditions can contribute to purslane nutritional composition and benefits [4], and possibly to its biological activity [5]. Uddin et al. [6] also reported that purslane flourishes in numerous biogeographical locations worldwide and are highly adaptable to many adverse conditions such as drought, saline, and nutrient-deficient conditions. P. oleracea has been identified as one of the richest vegetable source of omega-3 fatty acids [7], which is five times richer than spinach [8]. Purslane is rich in vitamin A, vitamin C, calcium, phosphorus and iron [5] and [6] antioxidants, such as α-tocopherol [9] and [10] and melatonin [7]. Its nutritional characteristics suggest that it can offer better nourishment than the 20 major crops currently providing most of our food needs [2]. Many research findings have been published worldwide regarding nutritional quality, medicinal properties, drought and salinity effect on the morpho-physiological attributes of this crop.
