采用气相色谱法和高效液相色谱法测定了几个澳大利亚马齿苋品种的脂肪酸组成和β-胡萝卜素含量。叶、茎和种子中总脂肪酸含量分别为1.5 ~ 2.5mg/g、0.6 ~ 0.9mg/g和80 ~ 170 mg/g。α-亚麻酸（C18：3 omega 3）分别占叶和种子中总脂肪酸含量的约60%和40%。未检测到长链omega-3脂肪酸。叶中β-胡萝卜素含量为22 ~ 30 mg/g鲜重。这些结果表明，澳大利亚马齿苋品种是α-亚麻酸和β-胡萝卜素的丰富来源。
The fatty acid profile and beta-carotene content of a number of Australian varieties of purslane (Portulaca oleracea) were determined by GC and HPLC. The total fatty acid content ranged from 1.5 to 2.5 mg/g of fresh mass in leaves, 0.6 to 0.9 mg/g in stems and 80 to 170 mg/g in seeds. alpha-Linolenic acid (C18:3omega3) accounted for around 60% and 40% of the total fatty acid content in leaves and seeds, respectively. Longer-chain omega-3 fatty acids were not detected. The beta-carotene content ranged from 22 to 30 mg/g fresh mass in leaves. These results indicate that Australian purslane varieties are a rich source of alpha-linolenic acid and beta-carotene.
