Weeds are one group of pests that significantly reduce crop yields and qualities, while herbicide use poses a risk to human health environment. Weed seed predation has been identified as potential biocontrol approach offering sustainable weed management. It causes substantial losses on species in fields, thus may result reduction use. This study aimed investigate the relevant patterns important...

Argemone mexicana Linn. (Linnaeus, 1753; Tournefort, 1694), is a herb of the Papaveraceae (poppy family) indigenous to the West Indies (Fig. 1). The study of this herb and its active principles is important, first to circumvent the serious epidemics of dropsy and glaucoma resulting from the unintentional ingestion of its seed oil in tropical countries; secondly to find a method of producing in ...

In this study, amount of morphine from poppy capsules (Papaver somniferum) was investigated using ultrasonic assisted extraction (UAE). Response surface methodology was used to estimate effective experimental conditions on the content extraction of poppy capsules. For this purpose, solvent/solid ratio (10-20 mL/500 mg sample), pH (1-13), time (30-60 min), and temperature (30-50°C) were chosen a...

Weasels may be cunning, we might admire the intelligence of dogs and cats, but we can be forgiven for expecting the jumping spider, a diminutive predator with a brain not much bigger than a poppy seed, to be one of Descartes’ automatons. Yet, jumping spiders, also known as salticids, alternate between entertaining and alarming us by planning prey-capture tactics ahead of time, adjusting their h...

Varied medicinal plants are known as a source of natural phytochemicals with antioxidant activities that can protect organisms from oxidative stress and from various chronic diseases. Papaver rhoeas has a long history of medicinal usage, especially for ailments in adults and children. The possible cytotoxicity, genotoxicity and potential antioxidant effect of plant extract isolated from flowers...

The actin cytoskeleton is a key target for signaling networks and plays a central role in translating signals into cellular responses in eukaryotic cells. Self-incompatibility (SI) is an important mechanism responsible for preventing self-fertilization. The SI system of Papaver rhoeas pollen involves a Ca(2+)-dependent signaling network, including massive actin depolymerization as one of the ea...

Recently, the NADPH-dependent short-chain dehydrogenase/reductase (SDR) salutaridine reductase (E.C. 1.1.1.248) implicated in morphine biosynthesis was cloned from Papaver somniferum. In this report, a homology model of the Papaver bracteatum homolog was created based on the x-ray structure of human carbonyl reductase 1. The model shows the typical alpha/beta-folding pattern of SDRs, including ...

INTRODUCTION Depression is one of the most frequent psychiatric disorders in the world with occurs with higher incidence in women. In the present study, the effect of water-alcoholic extract of Papaver rhoeas L. on forced swimming test (FST) in Swiss-Webster mice were examined. METHODS We used Swiss-Webster mice (20-25 g) to execute FST on them. The plant extract (1, 10, 30, and 100 mg/kg) wa...

DRUG ADDIcTIoN, especially through the use of poppy (Papaver somniferum Linn.) and hemp (Cannabis sativa Linn.), is the main concern of this paper. Although the use of these two plants in medieval Islam was extensive, yet little has been written on this timely subject by historians of medicine and pharmacology. Consulting contemporary original sources, it is my hope to sketch a history of their...
