Diarrhea is one of the most common causes death in young piglets. Porcine rotavirus (PoRV) belongs to genus Rotavirus within family Reoviridae, and considered be primary pathogen causing diarrhea Portulaca oleracea L. (POL) has been reported alleviate viral infections. However, antiviral effect polysaccharide (POL-P), an active component POL, on PoRV infection remains unclear. This study demons...

The Portulaca oleracea L. (Portulacaceae) is a cosmopolitan species with a wide range of biological activities, including antioxidant and neuroprotective actions. We investigated the effects of P. oleracea extracts in a 6-hydroxydopamine rat model of Parkinson's disease, a debilitating disorder without effective treatments. Chemical profiles of aqueous and ethanolic extracts of whole plant were...

A new tricyclic alkaloid named portulacatone (1), i.e., 5,6-dihydro-8,9-dihydroxy-11H-pyrrolo[2,1b] [3]benzazepin-11-one, together with eight known compounds, methyl 4-hydroxyphenylacetate (2), phydroxybenzaldehyde (3), vanillin (4), protocatechualdehyde (5), p-hydroxybenzoic acid (6), iseluxine (7), oleracein E (8), and (þ)-(R)-feruloyl malate (9) were isolated from aerial parts of Portulaca o...

The Pharmacological potential, such as antioxidant, anti-inflammatory, and antibacterial activities of Portulaca oleracea (PO) and Petroselinum sativum (PS) extracts are well known. However, the preventive properties against hepatocellular carcinoma cells have not been explored so far. Therefore, the present investigation was designed to study the anticancer activity of seed extracts of PO and ...

Portulaca oleracea L. is a medicinal plant find in Europe and Asia. This plant contains valuable secondary metabolite such as noradrenalin. Naturally the wild plant produce small amount of this secondary metabolites so induction of hairy roots can be useful to increase its production. In our research Agrobacterium rhizogenes strain AR15834 was used to induce hairy roots in the two-week leaf exp...

Crassulacean acid metabolism (CAM) was investigated in leaves and stems of the succulent C(4) dicot Portulaca oleracea L. Diurnal acid fluctuations, CO(2) gas exchange, and leaf resistance were monitored under various photoperiod and watering regimes. No CAM activity was seen in well watered plants grown under 16-hour days. Under 8-hour days, however, well watered plants showed a CAM-like patte...

Experiments were conducted in the greenhouse to assess root galling and egg production of three root-knot nematode species, Meloidogyne arenaria, M. incognita, and M. javanica, on several weeds common to Florida agricultural land. Weeds evaluated were Amaranthus retroflexus (redroot pigweed), Cyperus esculentus (yellow nutsedge), Eleusine indica (goosegrass), Portulaca oleracea (common purslane...
