The present study is about potential variations of bioactive compounds from different commercial brands of fenugreek; in relation to multiple organic solvent systems, antioxidants and antimicrobial assays. Total phenolic contents, total flavonoid contents, individual phenolic acids, and DPPH assays were checked whereas phenolics analysis was performed by HPLC spectrophotometrically. Antimicrobi...

Fenugreek (Trigonella foenum-graecum) is a medicinal plant which is widely used for its pharmacological properties. In this study the phenolic composition of fenugreek crude seeds originating from Morocco has been investigated. Extraction was performed from defatted seeds by a hydromethanolic solution using an Accelerated Solvent Extractor. HPLC technique coupled to negative ion electrospray io...

A systematic spectrofluorimetric study of the formation of ternary complexes of terbium ions (Tb3’) with ethylenediamine tetraacetic acid (EDTA) and a variety of bidentate organic ligands has been performed. Fourteen ligands (salicylic acid, quinolones and hydroxybenzene sulfonic acid derivatives) were examined as efficient energy donating chelators for Tb3+. The fluorescence properties of the ...

in other to study the effects of salicylic acid on reproductive characters of ‘elberta’ peach (prunus persica l. batsch) tree, an experiment was carried out based on randomized complete blocks design with four replications in commercial orchard, kerman, iran. the application of three concentrations of salicylic acid 0 (control), 1and 2 mm at swollen bud stage were used. results showed that appl...

Different sample pretreatment extraction techniques and analytical methods are often used for nitrate determination in vegetables; however, the effects of these variables have not been properly examined. Therefore, (oven-dried fresh extraction) (colorimetric method (salicylic (SM)) high-performance liquid chromatography (HPLC) were compared Chinese kale (K) morning glory (M) this study. Oven-dr...

This paper reports on the identification and characterization of a new ATP-binding cassette (ABC) transporter which was identified as a salicylic acid-induced gene from soybean (Glycine max cv. Williams 82) in a subtractive suppression hybridization approach. A fragment of an ABC-transporter gene was used to isolate a full-length cDNA clone for this gene with a length of 4750 bp. The encoded pr...

A new, cost-effective, and environmental-friendly cloud point extraction methodology was described for enrichment of copper, manganese and nickel in several water samples. The method involves the complexation of copper, manganese or nickel with 2-amino-6-(1,3-thiazol-2-diazeyl)-phenol at pH 7.0, then extraction into Triton X-114. After dilution of the surfactant-rich phase with acidified methan...

pot experiment was carried out to investigate the effects of ethylenediaminetetraacetic acid (edta) on some morphological characteristics of thlaspi caerulescens l., and also on the accumulation of lead (pb) and zinc (zn) in roots and shoots of t. caerulescens l.. experiments were then set up in three treated pots with doses of 3, 6 and 9 mmol kg-1 of edta and control pots (c: uncontaminated so...
