Pomegranate and pomegranate juices (PJs) have taken great attention for their health benefits in the last years. As there is an increasing concern about potential health benefits of ellagic acid, it is of great interest to evaluate alterations in ellagic acid concentration of commercial PJs. The purpose of this study is to analyze total phenolic, free and total ellagic acid content of six comme...

Perilla frutescens is an annual herb of the mint family native to East Asia. Polyphenols present in perilla have various structural varieties with large diversity of biological activities. It is direct influence the quality of perilla plant and their potential functions. Some of these products have been studied and proven to be effective source of phenolic antioxidants. The aqueous extract cont...

Phenolic compounds like phenolic acids, flavonoids and tannins are important plant metabolites that are important for many pharmacological activites.we had earlier demonstrated the wound healing activity, analgesic and anti inflammatory of the methanolic extract. The extract was investigated to determine the nature of the phytoconstituents responsible for these activities and this led to the is...

background: olive oil wastewater  contains chemical contents and organic materials that are resistant to biodegradation.  the existence of phenolic inhibitor compounds, toxicity to microorganisms in wastewater treatment units, unpleasant odor, high biochemical oxygen demand (bod) and chemical oxygen demand (cod), high suspended solids, and compounds resistant to biodegradation in such wastewate...

1. The extent to which phenolic derivatives of benzoic acid (seven); of phenylacetic acid (one); of 3-phenylpropionic acid (one) and of cinnamic acid (six) served as precursors of the urinary benzoic acid excreted by sheep was determined after administration as continuous drips via rumen or abomasal cannulas. 2. Phenolic derivatives of benzoic or of phenylacetic acid were not dehydroxylated to ...

using hplc, the seasonal changes in the phenolic compound content of the leaves ofthe gemlik olive cultivar (olea europaea l) has been investigated with respect to theeffects on the alternate bearing of the cultivar. for this purpose, the leaf concentrations ofoleuropein, chlorogenic acid, caffeic acid, 3-hydroxycinnamic acid, scopolin and pcoumaricacid were analyzed at 10 day intervals around ...

In the research it was examined the changes in total phenolic contents and seven major phenolic compounds (gallic acids, +(−) catechin, catechol, Chlorogenic acid, o-coumaric acid, rutin and quercetin) of two litchi cultivars (Purbi and Bedana) shoot tips and fruits (for zygotic embryos) collected in different months, in order to determine their effects on the explants browning during establish...

Phenolic profile, antioxidant potential and pigment contents of wild watercress (Nasturtium officinale L.) were studied to assess the potential for future studies and its applications in neutraceuticals and bioactive functional ingredients. Different extracts of watercress (roots, stem and leaves) were analysed for pigment composition, total phenolic contents, and radical scavenging activity. T...

To explore the effects of harvest time on phenolic compounds during wine fermentation, grape berries (Vitis vinifera L. cv. Vidal) were harvested at 17.5, 22.8 and 37.2 masculine Brix and were used to make dry wine, semi-sweet wine and icewine with low alcohol levels, respectively. Phenolic acids and flavan-3-ols were assayed during the fermentation of wines by means of reverse phase-high perfo...

The aim of this work was to establish the antioxidant capacity and the polyphenolic profile of Artemisia absinthium that could potentially be used in the human diet. An ultra-high performance liquid chromatographic method was used to identify and quantify individual phenolic compounds of the A. absinthium leaves. A total of 20 polyphenolic compounds were identified and quantified in A. absinthi...
