Studies have shown that phenolic compounds are important in human health.The purpose of this research was to examine the influence of rootstocks on phenolic compounds. The content of individual phenolic compounds in fruits was determined by HPLC. Total flavonoids content was measured using colorimetric method. Free radical scavenging activity on stable DPPH radicals was also evaluated. HPLC ana...

this study aimed to determine phenolic compounds of artemisia spicigera (family asteraceae) growing in east-azarbaijan province of iran. 20%, 40 % and 60% spe fractions of methanolic extract of a. spicigera, were subjected to reversed phase preparative hplc, with the mobile phase consisted of methanol and water. structural identification of phytochemicals by spectroscopic methods including uv a...

BACKGROUND Kelussia odoratissima Mozaff. is one of the newest genera of Umbelliferae which is represented by only one species. This sweet-smelling, self-growing monotypic medicinal plant is endemic to a restricted area in west of Iran and is locally called Karafse-koohi. The aerial parts of the plant are commonly used as a popular garnish and a sedative medicinal plant. There are several report...

Phenolic compounds are among the major classes of pollutants produced by industrial and agricultural activities. The amperometric biosensors have been mainly applied to the determination of phenolic compounds because of the advantages such as good selectivity, low cost, and easy automation. Amperometry is a method to measure the electric current that flows as a result of reactions generated at ...

Experimental studies have shown that phenolic compounds have antiproliferative and tumour arresting effects. The aim of this original study was to investigate the content of phenolic compounds (PhC) in flowers of Allium schoenoprasum (chive), Tragopogon pratensis (meadow salsify) and Rumex acetosa (common sorrel) and their effect on proliferation of HaCaT cells. Antiproliferative effects were e...

Phenolic composition of different extracts of honeydew melon seeds and their antioxidant activity was determined for the first time. Phenolic compounds were identified using a reversed phase high performance liquid chromatography with diode array detection (HPLC-DAD) method. Results showed the identification of five phenolic compounds in water extract namely gallic acid and its derivative, hydroxyb...

Trapping of arynes with various nucleophiles provides a range of heteroatom-functionalized arene derivatives, but the corresponding reaction with water does not provide phenol derivatives. Silver trifluroacetate (AgO₂CCF₃) can nicely solve this problem. It was found that in typical organic solvent, AgO₂CCF₃ readily reacts with arynes to generate trifluoroacetoxy organosilver arene intermediate,...

The dry olive residue (DOR) obtained from the olive oil extraction process has toxic components against plants and microorganism growth, particularly monomeric phenols. In this investigation nine saprobic fungi were found to be capable of completely removing these phenols from the solid after 20 weeks of growth, although the rate depended on the type of fungi and phenol. Results showed that mos...
