New developments in the realm of skin rejuvenation such as phytotherapy are at an astounding increasing pace in the cosmeceutical market. Yet, many of these products that are classified as cosmeceuticals are tested less vigorously and do not have to be approved by the Food and Drug Administration to establish efficacy and safety. Thus, as clinicians, we must ask the question, ‘‘Is there science...

The monoterpenes are secondary metabolites of plants. They have various pharmacological properties including antifungal, antibacterial, antioxidant, anticancer, anti-spasmodic, hypotensive, and vasorelaxant. The purpose of this research was to review the cardiovascular effects of monoterpenes. The data in this resarch were collected using the Internet portals Pubmed, Scopus, and ISI Web of Know...

Babaçu (A. speciosa), Buriti (M. flexuosa), and Macaúba (A. aculeata) are palm trees typical of the ecotone area between Cerrado and the Amazon rainforest. The purpose of this study was to evaluate the antimicrobial potential of the extracts prepared from the leaves of those palms as well as determine their chemical compositions. The ethanol extracts were prepared in a Soxhlet apparatus and tes...

Monoterpenes, the chemical constituents of essential oils found in plants, are known biologically active compounds. The present study was conducted to investigate the inhibitory effects of 30 monoterpenes including monoterpene hydrocarbons and oxygenated monoterpenes on seed germination and seedling growth of Amaranthus retroflexus, Chenopodium album and Rumex crispus under laboratory condition...

BACKGROUND Pycnocycla spinosa Decne. ex Boiss is an aromatic plant which showed relaxant effects on isolated ileum contractions and antidiarrheal activity. Thirty four components have been extracted from P. spinosa essential oil, of which several major constituents were found to show seasonal variation. OBJECTIVES The aim of this work is to evaluate the diurnal variation of its oil constituen...

The aim of the research was to determine effects top-pruning time on flower yield, rose oil content and constituents in oil-bearing rose. Five-year old plants were top-pruned three different dates starting from 15 March (early), 30 (middle) ending April (late) before they started new growth spring. In addition, non-pruned (untreated) parcels used as controls. Top pruning significantly affected ...

Ongoing climate change in recent decades exacerbated the decline agricultural water use, and seawater irrigation could feasibly alleviate shortage of resources, which restricts viticulture some countries. However, studies on effects grape volatiles are limited. Herein, ‘Reliance’ grapevines were irrigated with diluted (10% concentrations) field since pea-size berry stage (S1), EL 32 (S2), pre-v...

Lemongrass is a plant that produces essential oils, which contain citronellal, citronellol, and geraniol. These compounds are known to be used as antimicrobials antioxidants. Nanotechnology one of the technological innovations can medium for sending non-polar active components, such oils. The research was study effect citronella oil concentration, surfactant-cosurfactant ratio, speed homogeniza...

Photocatalysts able to trigger the production of singlet oxygen species are topic intense research efforts in organic synthesis. Yet, challenges still exist improving their activity and optimizing use. Herein, we exploited benefits plasmonic nanoparticles boost such photocatalysts via an antenna effect visible range. We synthesized silica-coated silver (Ag@SiO2 NPs), with silica shells which th...

Abstract Background Rosa damascena is an aromatic rose species, which cultivated for its essential oil, and widely used in perfume, cosmetic, pharmaceutical, food industries the world. This experiment was conducted to evaluate oil morphological variations of 26 Damask genotypes. For this purpose, effect harvest time, i.e., early morning or evening, sampling type, fresh dried petals, on content ...
