     Excerpt Portulaca oleracea is an herbaceous plant consumed in Italy, the United Kingdom, Spain, Greece, Turkey, Iran, Malaysia, the Philippines, China, North Africa, Australia, the United States, Brazil, & Mexico. It provides substantial contributions of minerals, polysaccharides, fatty acids, proteins, alkaloids, terpenoids, sterols, phenols, flavonoids, & vitamins, which together or individually provide neuroprotective, antimicrobial, antidiabetic, antioxidant, anti-inflammatory, antiulcerogenic, anticancer, & anticholinesterase properties.

   • According to MIAO L (2023)

     Excerpt Male C57BL/6 mice had 14-week ad libitum access to a high-fat rodent diet containing 60% kcal% fat to induce obesity & diabetes whereas purslane extract (200 mg/kg/day) was administered during the last 4 weeks via intragastric gavage. This study supported that purslane protected endothelial function, & inhibited ER stress and oxidative stress in vasculature through AMPK/eNOS activation, revealing its therapeutic potential against vascular complications in diabetes.

   • According to Rakhshandeh (2022)

     Excerpt Based on the anti-diabetic, antioxidant, & anti-hyperlipidemic potential of Portulaca oleracea (PO), this study aimed to evaluate the protective effect of this plant extract on streptozotocin-induced type-I-diabetes-associated reproductive system dysfunction & inflammation. Results: Our results showed that streptozotocin-induced diabetes significantly increased food & water consumption; increased glucose, MDA, TGF-β1, & TNF-α levels; & decreased the seminiferous tubules diameter, sperm count & motility, levels of LH, testosterone, total thiol, VEGF, & SOD activity.

   • According to Petropoulos SA (2020)

     Excerpt Seeds contained the highest amount of fats & energy (15.03 ± 0.06 g/100 g dry basis (db) & 459 ± 1 kcal/100 g db, respectively), while seedcakes from CE2 had the highest content in proteins & ash (31.20 ± 0.03 & 4.27 ± 0.06 g/100 g db, respectively). HE & CE1 oils had slightly higher amounts of α-linolenic (39.67% & 39.57%, respectively) than linoleic acid (35.44% & 35.13%, respectively), whereas CE2 oils contained twice as much linoleic as α-linolenic acid (49.77% & 24.18%, respectively).

     Excerpt The results demonstrated that PO was an effective anti-oxidative agent, which could, to some extent, reverse APAP-induced hepatotoxicity by regulating the reactive oxygen species (ROS) in the liver of mice. Portulaca oleracea L., a widely distributed weed, has been used as a folk medicine in many countries.

   • According to Damavandi RD (2021)

     Excerpt The aim of the present study was to examine the effect of PO hydroalcoholic extract in patients with non-alcoholic fatty liver disease (NAFLD). The findings of our study show that PO extract at the dose of 300 mg/day for 12 weeks has no significant effects on liver enzymes, lipid profile, & glycemic indices in patients with NAFLD.
