Abstract

Portulaca granulatostellulata and P. edulisare two subspecies ofcommon purslane. The biomass of both plants was similar; however, with long upright stems and a long vegetative period, P. edulis production was easier. Both subspecies were rich in vitamin C and flavonoids, main organic nutrients’ contents in 25-d-old plants were higher than those in15-d-old plants, and were higher in P. granulatostellulata. Both purslanes were rich in minerals, with the K content being the highest, and was higher in P. edulis, whereas the Ca content was higher in P. granulatostellulata. A similarly high content of polyunsaturated fatty acid, particularly α-linolenic acid, in both purslanes showed their high value in balancing the ω-6/ω-3 intake ratio. Furthermore, all the contents of nitrate and heavy metals in this study were within the safe range, and the oxalic acid content in mature plants decreased to the high level of oxalic acid in vegetables. In brief, both purslanes are excellent reserve crops for use as vegetables and medicines. P. edulis has advantages over P. granulatostellulata regarding plant appearance and the K content. P. granulatostellulata has advantages regarding Vc, flavonoid and other mineral contents; Both purslanes are similar in fatty acid composition and are suitable for picking at a mature stage.
