【 摘 要 】

The present study was designed to investigate the protective effect of the aqueous extract of Portulaca oleracea against hyperglycemic, oxidative damage and inflammation in the serum of streptozotocin (STZ)-induced diabetic rats. In the present study, the rats were divided into the following groups of 8 animals each: control, untreated diabetic, 3 Portulaca oleracea (100, 200, 400 mg/kg/d)–treated diabetic groups. At the end of the 4-week period, glucose, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), malondialdehyde (MDA), glutathione (GSH), and total antioxidant status (TAS) levels were measured. STZ caused an elevation in the serum levels of glucose, MDA, IL-6, and TNF-α with reduction in the levels of GSH and TAS (P < .01). Portulaca oleracea ameliorated glucose, MDA, IL-6, TNF-α, GSH, and TAS levels in diabetic groups versus to the untreated groups (P < .05). Taken together, Portulaca oleracea prevented hyperglycemia by preventing the oxidative stress and inflammation.
