摘要

Total phenols (a) and total flavonoid content (b) in leaf and stem of Portulaca oleracea at vegetative and flowering growth stages. Different small letters indicate significant difference between the means based on Duncan test (P ≤ 0.05). L-V (leaf-vegetation), S-V (stem-vegetation), L-F (leaf-flowering) and S-F (stem-flowering). Values are mean ± S.D. of three replicates
