Common purslane (Portulaca oleracea L.) is an annual weed rich in omega-3 fatty acids which is consumed for its edible leaves and stems. In the present study six different genotypes of common purslane (A-F) were evaluated for their nutritional value and chemical composition. Nutritional value and chemical composition depended on genotype. Oxalic acid content was the lowest for genotype D, where...

Purslane (Portulaca oleracea L.) is a common weed that grows all over the world and is one of the most widespread weed species in summer crops. However, it has great potential to become a new crop since its identification as one of the best plant sources of -3 fatty acid, -linolenic acid, as well as some antioxidants ( -tocopherol, -carotene, ascorbic acid, and glutathione). Several other featu...

The tomato industry in South Florida (USA) is seriously affected by recently emerging Tomato chlorotic spot virus (TCSV). Western flower thrips, Frankliniella occidentalis (Pergande), and common blossom schultzei (Trybom) (Thysanoptera: Thripidae), are the two known vectors of TCSV Florida. In present study, presence thrips 24 flowering ornamental plant species was observed vectors, as well mel...

Eleusine indica and Portulaca oleracea are two common weeds in peanut crops in southern Córdoba. Two chemicals are frequently used to control them, quizalofop for grasses and lactofen for dicots. The objective is to study the effects of quizalofop and lactofen on cuticle ultrastructure in E. indica and P. oleracea, respectively. In the lab, quizalofop was applied on E. indica and lactofen on P....

169 Abstract Two proteinous compounds (A and B) were isolated by gel filtration chromatography of the acetone precipitate of the aqueous extract of Portulaca oleracea L. plant. Comparative apparent molecular weights determination by gel filtration using standard proteins gave a value of 28184 and 2291 dalton respectively.The effect of the isolated proteinous compounds A , B and the hormone of i...

Purslane (Portulaca oleracea L.) is a fleshy herbaceous plant. So far, little information is available on the response of this plant to combined drought and heat stress. In this study, changes in physiological and metabolic levels were characterized after treatments with drought, heat and combined stresses. Both individual and combined stress treatments increased malondialdehyde (MDA), electrol...

The essential oil composition of Peumus boldus and Drimys winterii was analyzed by means of capillary GC-FID and GC-MS. More than 96% of the total oil components (43 and 54 compounds, respectively) were identified, with ascaridole (51.17 ± 9.51), p-cymene (16.31 ± 2.52) and 1,8-cineole (14.45 ± 2.99) as the main compounds in P. boldus and g-eudesmol (21.65 ± 0.41), followed of elemol (12.03 ± 0...

Objective(s) Portulaca oleracea L. is a herbaceous weed from portulacaceae family. It can be found in many parts of the world. Modern pharmacological studies have demonstrated that P. oleracea have antioxidant effects. The protective effect of aqueous and ethanolic extract of P. oleracea against cisplatin-induced renal toxicity was studied in rats. Materials and Methods Single intraperitonea...
