Purslane: A Review of its Potential for Health and Agricultural Aspects

Purslane (Portulaca oleracea L.) is a common weed that grows all over the world and is one of the most widespread weed species in summer crops. However, it has great potential to become a new crop since its identification as one of the best plant sources of?-3 fatty acid, ?-linolenic acid, as well as some antioxidants (?-tocopherol, ?-carotene, ascorbic acid, and glutathione). Several other features distinguish this species: high content of crude protein, water-soluble polysaccharides useful as gums, and good tolerance to salinity. This review summarizes purslane's origin, botanical, and physiological features while its nutritional and medical properties are reported in reference to several studies carried out on its chemical properties. Finally, its cultivation potential is discussed and future uses are proposed for this species, mainly as a component in ready-to-use vegetables (especially in mixed packaging) but also for other cultivation purposes.
