A sensitive and reliable method of liquid chromatography-electrospray ionization/tandem mass spectrometry (LC-ESI/MS/ MS) was developed and validated for determining 1,3-dimethylamylamine (1,3-DMAA) and 1,4-dimethylamylamine (1,4-DMAA) in geranium plants (Pelargonium graveolens). The sample was extracted with 0.5 M HCl and purified by liquid-liquid partition with hexane. The parameters for reve...

1,3 dimethylamylamine or methylexaneamine (DMAA) is a synthetic pharmaceutical patented in the 1940s as a nasal decongestant which can be used as a recreational stimulant. Alleged to occur in nature, DMAA has become a widely used ingredient in sports food supplements, despite its status as a doping agent and concerns over its safety. There is now some doubt as to whether it can be sourced natur...

Development of biologically inspired experimental processes for the synthesis of nanoparticles is an important branch of nanotechnology. In this paper, we report on the use of geranium leaves (Pelargonium graveolens) and its endophytic fungus in the extra-cellular synthesis of gold nanoparticles. Sterilized geranium leaves and an endophytic fungus (Colletotrichum sp.) growing in the leaves were...

background: natural products are proved to play a good role as an alternative to synthetic chemicals in clinical conditions. previous studies showed that pelargonium graveolens has anti-inflammatory and antifungal activity against candida albicans . the aim of this study was to evaluate the efficacy of essential oil of pelargonium graveolens in the treatment of denture stomatitis . materials an...

Geranium (Pelargonium graveolens L’Hér.) is an important commercial horticultural plant extensively used in outdoor landscaping. Seed emergence has always remained a problem geranium due to its hard seed nature. Hence germination and other emergence-related attributes need be adequately tested. The purpose of this study was evaluate the seedling growth geraniums under different types containers...

Geraniaceae have emerged as a model system for investigating the causes and consequences of variation in plastid and mitochondrial genomes. Incredible structural variation in plastid genomes (plastomes) and highly accelerated evolutionary rates have been reported in selected lineages and functional groups of genes in both plastomes and mitochondrial genomes (mitogenomes), and these phenomena ha...

to evaluate the effect of limited application of nitrogen (n) on the height control of geranium(pelargonium hortorum) and improving its quality performance, an experiment was conducted based on acomplete randomized block design with three replications in the greenhouse environment through theyears 2011-2012. geranium seedlings were cultivated in the pots filled with peat-based substrate (peat, ...

The effects of two Iranian medicinal plants including Zataria multiflora and Geranium pelargoniumwere evaluated on growth-inhibiting of some toxigenic fungi such as Aspergillus flavus, A. parasiticus, A.ochraceus and Fusarium verticillioides. In this study, standard Z. multiflora and G. pelargonium essentialoils (EOs) were diluted in 0.01% dimethyl sulfoxide. Different dilutions of Z. multiflor...

ABSTRACT A series of laboratory tests were conducted to investigate potential effects of fungus gnat (Bradysia impatiens) feeding damage on susceptibility of geranium seedlings (Pelargonium x hortorum) to infection by the root rot pathogen Pythium aphanidermatum. Effects were compared with those from similar tests in which the seedlings were mechanically wounded by severing the root tip with a ...
