pelargonium graveolens/抗氧化劑

The decoction of Pelargonium graveolens yields an antioxidant-rich extract and a water-soluble polysaccharide. This study aims (1) to investigate the effect of process parameters (extraction time and temperature) on the antioxidant activity of the decoction and

The antioxidant effects of essential oil and monomer as well as residue and waste water after distillation from buds, stems and leaves of Pelargonium graveolens were studied by the method of 1,1-diphenyl-2-picryl hydrazyl free redical (DPPH*). It showed that each sample in the test had the

BACKGROUND Despite the vast exploration of microbes for plant health, there is a lack of knowledge about the synergistic effects of specific microorganisms in sustainable agriculture, especially in medicinal plants such as Pelargonium graveolens L'Hér. The aim of this study was to evaluate how

BACKGROUND Exposure to the pyrethroid pesticide deltamethrin has been demonstrated to exert a wide range of effects on non-targeted organisms. The beneficial effects of geranuim essential oil (EO) as an antioxidant has been assessed in deltamethrin (DL) orally administered mice by studying whether

BACKGROUND Rose-scented geranium (Pelargonium graveolens L'Hér.), which is used in traditional Tunisian folk medicine for the treatment of hyperglycaemia, is widely known as one of the medicinal herbs with the highest antioxidant activity. The present paper is conducted to test the hypoglycemic and

Hydrogen peroxide is an important signalling molecule, involved in regulation of numerous metabolic processes in plants. The most important sources of H2 O2 in photosynthetically active cells are chloroplasts and peroxisomes. Here we employed variegated Pelargonium zonale to characterise and compare

In this study we exposed variegated leaves of Pelargonium zonale to strong sunlight (>1100μmolm-2s-1 of photosynthetically active radiation) with and without paraquat (Pq), with the aim to elucidate the mechanisms of H2O2 regulation in green and white tissues with respect to the

Essential oils are natural antimicrobials that have the potential to provide a safer alternative to synthetic antimicrobials currently used in the food industry. Therefore, the aim of this study was to evaluate the antimicrobial and antioxidant activities of essential oils from white wormwood,

The antioxidative activity of geranium (Pelargonium inquinans Ait) and its active component was investigated under in vitro and cellular oxidative stress models. The MeOH extract, and n-hexane, EtOAc, BuOH and H(2)O fractions from geranium showed strong 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical

The present investigation was aimed to find out the sun protection factor (SPF) and antioxidant potential of geranium essential oil (GEO) and calendula essential oil (CEO) because having a combination of these two properties moves up the oils as an active ingredient of various cosmeceutical

Flavonoids and hydrolyzable tannins isolated from Pelargonium reniforme were evaluated for their antioxidant ability using a 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical generating system and a luminol-dependent chemiluminescence assay. In both assays, the polyphenols tested showed higher radical

Eucalyptus bridgesiana, Cymbopogon martinii, Thymus vulgaris, Lindernia anagallis, and Pelargonium fragrans are five species of herbs used in Asia. Their essential oils were analyzed by GC-MS, and a total of 36 components were detected. The results of our study indicated that, except for the

In Tunisia, Pelargonium graveolens is widely consumed as a food aromatizing hydrosol. Recent studies have shown the potential of plant solvent-free extracts as food and pharmaceutical natural additives. Accordingly, in this study, we investigate the phenolic content, the volatile fractions of green

In this work, the chemical composition, the antioxidant, and the antibacterial activities of two Moroccan essential oils less studied, extracted from Pelargonium asperum and Ormenis mixta, were investigated. According to the gas chromatography coupled to mass spectrometry analysis, citronellol

OBJECTIVE We tested in mice the hypothesis that ingestion of infusions of green tea, white tea, or the aromatic plant Pelargonium purpureum increases total antioxidant capacity (TAC) of plasma and organs. METHODS Twenty-five mice were randomly assigned to five groups, each of which received by
