portulaca quadrifida/carbohydrate

The C(4) succulent plant Portulaca oleracea shifts its photosynthetic metabolism to crassulacean acid metabolism (CAM) after 23 d of withholding water. This is accounted by diurnal acid fluctuation, net nocturnal but not day CO(2) uptake and drastic changes in phosphoenolpyruvate carboxylase (PEPC)

The in vivo activity of xanthine dehydrogenase (E.C. 1.2.1.37) was followed in leaf discs excised from illuminated or darkened plants. In cotyledons of Pharbitis nil, 24 hours of darkness enhanced the in vivo activity of xanthine dehydrogenase which increased between 2 to 5-fold depending on the

This study was designed to investigate the inhibitory activities of 5,7-dimethoxy-3-(2'hydro-xybenzyl)-4-chromanone (5,7-D chromanone) isolated from Portulaca oleracea L. on carbohydrate digesting enzymes and its ability to improve postprandial hyperglycemia in streptozotocin-induced diabetic mice.

Nursery grown plants of Nerium oleander, Pogonatherum crinitum, and Portulaca oleracea were observed to remove fluoride up to 92, 80, and 73%, respectively, from NaF solution at the concentration of 10 mg L-1 within 15 days. Concentration range of 10-50 mg L-1 of fluoride revealed a constant

Wild edible plants (WEPs) have been consumed since ancient times. They are considered as non-domesticated plants that grow spontaneously in nature, particularly in forests and bushlands, where they can be found and collected to be incorporated into human nutrition. Increasingly, WEPs are gaining

Purslane (Portulaca oleracea), grown under greenhouse conditions, was harvested at three growth stages and analyzed for total solids, total protein, ash, soluble carbohydrate, and fructose/fructane in whole plants, leaves, stems, and roots. Significant increases were observed in total solids and

Lectins are carbohydrate-binding proteins broadly distributed in plants and have several biological functions, including antimicrobial action. Portulaca elatior is a Caatinga plant whose chemical composition and biotechnological potential have not been extensively studied. In this work, a lectin was

The uniqueness of purslane (Portulaca spp.) as the richest vegetable source of omega-3 (omega-3) fatty acids is well documented. However, purslane has not been domesticated or fully evaluated for its nutritive value. The objective of this study was to determine the influence of planting date on

Heat stress is a major abiotic stress that limits plant growth and productivity. In recent years, proteomic investigations provide more information for understanding the sophisticated heat-responsive molecular mechanism in plants at systematic biological level. The heat-responsive proteomic patterns
