Review of research literatures on pharmacological activities of Portulaca oleracea
3.1 Anti-microbial activity
Ramesh & Hamumantapa42 had reported the phytochemical and anti-microbial activity in aerial parts of chloroform and ethanolic extracts of
portulaca oleracea by agar diffusion method against five bacteria and three fungi (bacteria like staphylococcus aureus, bacillus cereus, Klebisilla
pneumonia,aspergillus niger and nerospora crassa). Ethanolic crude extract showed maximum effect on organisms like staphylococcus aureus, klebisilla
pneumonia and neurospora crassa, Whereas chloroform extract showed moderate effect on Klebisilla pneumonia, aspergillus niger and nerospora crassa.
The results of this present study supported the folklore usage of the studied plant and suggest that, this plant extract posses compounds which is
having antimicrobial agent in the form of drugs for the therapy of infectious diseases caused by pathogens.
Zhao et al57 investigated the effects of Portulaca oleracea extracts on growth performance and microbial populations in the ceca of broilers.
Results showed P. oleracea extracts have no distinct influence on intestinal pH and that P. oleracea extract supplementation significantly altered the cecal
bacterial community without affecting the intestinal pH.
