In this contribution, pressurized liquid extraction (PLE) has been employed to isolate bioactive compounds from three native Romanian plants, oregano (Origanum vulgare), tarragon (Artemisia dracunculus) and wild thyme (Thymus serpyllum). Different PLE conditions have been tested including extraction with water, ethanol and their mixtures in a wide range of extraction temperatures (50-200°C), an...

Water solutions of extracts were investigated for total phenol content, flavonoid content and antioxidant activity. Susceptibility to degradation of water solutions of plant extracts, under light and in the dark, during storage at room temperature was investigated in order to determine their stability prior to their application for fortification of food products. Large dispersion of total pheno...

para-Selective processes for the chlorination of phenols using sulphuryl chloride in presence various sulphur-containing catalysts have been successfully developed. Several chlorinated phenols, especially those derived by para-chlorination phenol, ortho-cresol, meta-cresol, and meta-xylenol, are significant commercial importance, but reactions such not always as regioselective would be desirabl...

Vitex mollis is used in traditional Mexican medicine for the treatment of some ailments. However, there are no studies on what happens to the anti-inflammatory activity or antioxidant properties and total phenolic content of leaves and stem extracts of Vitex mollis during the digestion process; hence, this is the aim of this work. Methanolic, acetonic, and hexanic extracts were obtained from bo...

objective(s):astrodaucus persicus, apiaceae, is used as vegetable or food additive in some parts of iran. the essential oils of different parts of astrodaucus persicus from kordestan province were analyzed for the first time and compared with other regions. in this study, antioxidant activities and total phenols determination of aerial parts essential oils and root fractions of a. persicus were...

Dry olive mill residue (DOR) from the olive oil production by two phase centrifugation system was fractionated by a consecutive continuous solid-liquid extraction obtaining the EAF, PF, MF and WF fractions with ethyl acetate, n-propanol, methanol and water, respectively. The chemical, chromatographic and mass spectrometric analyses showed EAF, PF and MF to be mainly composed of simple phenols, ...
