Plant extract, a natural source containing complex mixture of compounds, offers many properties such as antiparasitic, antibiotic, antioxidant, anti-hypertensive, antiviral, insecticide, anticancer, antifungal, hypoglycemic properties. Recent research has been focused on developing formulation the plant extracts not only to deliver them safely but also to enhance its therapeutic efficacy. Nanotechnology-based strategies have been proposed as a system that can be used to formulate plant extracts.

The corrosion inhibition of carbon steel (CS) in 3 M HCl was thoroughly investigated in the presence and absence of areca plant extracts as a green corrosion inhibitor. The effect of solution temperature and different amounts of areca plant extracts was examined through gasometric, colorimeter and atomic absorption spectroscopy techniques. Surface studies were screened by scanning electron microscopy (SEM) technique. The results of these techniques show that areca plant extracts (arecanut husk extract, arecanut seed extract and areca flower extract) behave as a nontoxic corrosion inhibitor for

Obesity is a disease that has reached epidemic proportions across the world. Many types of treatments have been used to combat obesity including using synthetic drugs such as sibutramine and orlistat.

Phytochemical analysis of both HEA1 and the crude plant extract showed the presence of phenolics, tannins and saponins. Saponins were the predominant secondary metabolites and were mostly abundant in the plant extract and to a lesser extent in the active compound. Steroidal saponins, tannins and phenolics were also detected in the plant extract, but only the phenolics were detected in the active compound. The results of the phytochemical analysis showed that those compounds that were not present in the active compound could be removed from the crude extract during the TLC purification process.

Abstract:
Mentha piperita and Melissa officinalis are both well-known medicinal plants that have applications in traditional medicine. In this research the antibacterial activity of the ethanol extracts of M. piperita and M. officinalis was examined against 14 bacterial strains via the microdilution method. Minimum inhibitory concentrations of ethanol extracts of both plant species ranged from 0.312 to 20 mg/mL. Standard strains of Staphylococcus aureus ATCC 25923 at a concentration of 0.312 mg/mL and Bacillus subtilis ATCC 6633 at a concentration of 1.25 mg/mL showed the highest sensitivity to the etha

Abstract:
Anti biotic resistant bacteria have posed a serious threat to world health in recent years, forcing the investigation of alternate sources for anti bacterials. Higher plants are a key source of medicinal compounds. The objective of this study was to evaluate the anti bacterial properties of C. speciosus against gram-negative E. coli and gram-positive Staphylococcus aureus, to explore its potential as a natural alternative to conventional anti bioti cs. Leaves, stems, and rhizomes of C. speciosus were extracted using hexane, methanol, and water as solvents with reflux, sonication and maceratio.

Abstract:
We investigated the possible attraction of species of Helicoverpa and Heliothis to host plant odors and to male pheromone as a prelude to a larger investigation of host chemical effects on moth sexual and reproductive behavior. Both sexes of H. armigera and H. peltigera were attracted to particular host plants or host plant extracts. Heliothis virescens was also found to be attracted to a flowering shrub it may use as a nectar source. Unmated females of H. armigera and H. peltigera were attracted to live males and to a male pheromone extract prepared from exposed filter papers in cages of male

Abstract:
Grape Seed Extract (GSE) has received acceptance almost globally as an ingredient for human consumption. It is one of the more widely used botanical extracts, due to increasing scientific findings supporting health benefits. However, it remains a specialty item relative to global commodities. In the United States, GSE has ranked among the top 20 best-selling dietary supplements in the Food, Drug and Mass Market channel. The motivation behind purposeful adulteration in commercial products is financial gain (also known as economically motivated adulteration) and to increase the concentration in

Abstract:
Arnica montana flower extract is a popular ingredient for production of ointments, gels, and homeopathic preparations. Due to nomenclatural confusion, particularly the use of the vernacular name ”arnica” for a number of plant species, difficulties in cultivation, and high prices for wild-harvested plant material, adulteration is quite common. Some of the known adulterants and confounding species for A. montana flowers are other Arnica species (A. angustifolia, A. chamissonis, A. chamissonis subsp. foliosa), “Mexican arnica” (Heterotheca spp.), and different species from the Asteraceae family (

Abstract:
Hemisarcoptes (Acari: Hamisarcoptidae) is a parasite of scale insects (Diaspididae), tenacious pests of vascular plants. Hemisarcoptes also has a stenoxenic phoretic (dispersal) relationship with Chilocorus (Coleoptera: Coccinellidae). Chilocorus feeds on diaspidids, transports mites as they feed, and has been applied to the control of scales, with limited success. U.S.-Israeli cooperation focused on this mite-beetle interaction so that a two-component system could be applied to the control of scale insects effectively. Life history patterns of Hemisarcoptes were investigated in response to ho

Review question / Objective: The aim of this review is to examine inhibitory effect of functional components in extracts from edible nuts on α-glucosidase activity. At the end of this review the following questions will be addressed by summarizing data of in-vitro studies: which nut extract has the strongest inhibitory effect? Which functional component (e.g. polyphenols) has the strongest inhibitory effect against α-glucosidase? Are there any differences between inhibition of α-glucosidase from different sources (e.g. yeast and mammalian)? Condition being studied: Any papers looking at inhibi
