pomegranate (punica granatum l.), lythraceae, is mainly grown in mediterranean region. it is one of the major cultivated productions of iran, which have been used in folk medicine for many centuries. it has been proved that pomegranate has a high antioxidant activity and is effective in the prevention of atherosclerosis. this study compares the antioxidant activity, total phenolic and flavonoid...

Direct methanolic water extracts without any further treatment or extracts submitted to an acidic treatment yielded similar amounts of tyrosol present in olive oil: 216 ␮g (in 50 mL). From this value, urinary recoveries of tyrosol were unrealistic because they were 131.5–327.8% of the dose administered. When the tyrosol content was estimated after NaOH digestion and sonication of olive oil, the...

background & aim:extracts of roselle calyx,   possess compounds which could be considered as a great source of natural antioxidants.   in this project, antioxidant activities, phenolic compounds content and their   correlation analysis on calices of roselle (hibiscus sabdariffa) was investigated.  experimental: total polyphenolic compound, flavonoids and anthocyanins were determined spectrophot...

A methodology based on a solid phase extraction (SPE) was optimized for the recovery of phenolic compounds from spent fermentation broth generated Biofene® (trans-?-farnesene) production. For this purpose, two resins (XAD-2 and HP-20) three desorption solutions (water, 50/50 ethanol/water, ethanol) were tested. The most efficient resin revealed to be HP-20, using ethanol as solution, reaching a...

Nowadays use of edible films and coatings is increasing due to their biodegradability properties. Fish gelatin obtained from fish skin wastes can be used as an appropriate protein compound for preparing the edible films. It can be also replaced pork gelatin. In this study, films were prepared from fish gelatin and phenolic compound caffeic in four levels of 0%, 1%, 3% and 5% at pH>10, temperatu...

Phenolic compound profiles were investigated by HPLC-MS in two consecutive years to assess genotypic variation in berry skins of nine red Vitis vinifera cultivars. The results showed that the types and levels of phenolic compounds greatly varied with cultivar. Common wine grape cultivars such as Syrah, Cabernet Sauvignon, Cabernet Gernischt and Merlot contained more types of anthocyanins, flavo...

The present study was conducted to characterize various bioactive phytoconstituents in leaf aqueous extract of Abutilon indicum using FTIR and UV-Vis spectroscopy. Phytochemical profiling of leaf aqueous extract was carried out and the total phenolic compounds and flavonoids were determined spectrophotometrically following the standard methods. FTIR and UV-Vis profiles showed the presence of ph...

Olive from Olea europaea is native to the Mediterranean region and, both the oil and the fruit are some of the main components of the Mediterranean diet. The main active constituents of olive oil include oleic acid, phenolic constituents, and squalene. The main phenolic compounds, hydroxytyrosol and oleuropein, give extra-virgin olive oil its bitter, pungent taste. The present review focuses on...
