The aim of this work was to characterise the phenolic compounds in artichoke (hearts) by using HPLC coupled to DAD-ESI-QTOF-MS, which proved useful in characterising 61 phenolic and other polar compounds. Notably, of the 61 compounds characterised, 34 new phenolic compounds with their isomers have been tentatively characterised in artichoke for the first time, namely: 3 hydroxybenzoic acids, 17...

BACKGROUND The main objective of this research was to study photocatalytic oxidation of phenol in aquatic solutions by using of UV, TiO2 and the combination of them. Phenol compounds are widely used in industries and other daily life. Highly toxicity and carcinogenicity of these compounds can causal considerable adverse effects on the aquatic ecosystems and human health. METHODS The study was...

Lemon verbena (Lippia citriodora) belongs tothe Verbenaceae (shahpasand) family. L.citriodora is chemical  composition of the leaves plant have antimicrobial properties, refrigerant, anti-headaches one-sided, anti- pains nerve and housing, carminative, helping to digestion, relaxation, dizziness, colds therapy,  memory Booster and etc.  In this study, phenolic compounds of <em...

plant materials have been found useful in decontamination of water polluted with phenolic compounds. the detoxification effect is due to peroxidases contained in plant tissue. enzyme mediated oxidative coupling of phenol is followed by precipitation of the formed polymer and its removal from the aqueous phase. a synthetic wastewater buffered at ph = 7.4 containing 0.9 mm phenol was treated in t...

Guava (Psidium guajava L.), is adapted to an extensive range of soils, however, its development is strongly affected by salinity. Environmental stresses are of the major and influential factors in the amount of secondary metabolites, especially phenolic compounds present in plants. The purpose of this investigation was to study the leaf antioxidant and flavonoid contents (catechin, quercetin an...

The objective of this study was to determine important chemical characteristics of a full-strength liquid smoke, Code 10-Poly, and three refined liquid smoke products (AM-3, AM-10 and 1291) commercially available (Kerry Ingredients and Flavors, Monterey, TN). The pH of the products were significantly different (P < 0.05) and ranged from 2.3 (Code 10-Poly) to 5.7 (1291). The pH was inversely cor...
