Omega‐three fatty acids in purslane (Portulaca oleracea) Tissues

Abstract

Total lipids and omega‐3 fatty acids in purslane (Portulaca oleracea) were determined in leaves, stems and whole plants at three ages. Significant differences (P<0.05) existed in levels of total lipids among ages and between leaves and stems, but no relationship of age to plant part (>O5) was found. Contents of 18:3ω3,20:5ω3, 22:5ω3,22:6ω3,18:2ω6 and 18:loω9 showed that leaves were the richer source of omega‐3 acids at each age.
