The quantitative determination of total phenols, ellagic tannins and gallic and ellagic acids in the peel of the Tunisian pomegranate variety Chelfi, has been carried out. The ellagic tannin content is prominently less than the amount of total phenols, which led us to look for the presence of the condensed tannins. The determination of the content of catechic tannins in eight Tunisian varieties of the pomegranate was carried out using weekly samples over a period of 2 months. 
of characterization Extraction and compounds of pomegranate peel
This paper includes a detailed description of the methods used to extract some bioactive compounds like Tannins and some dyes from pomegranate peel. Experiments were carried out also to select the
Enzyme-assisted Extraction of Polyphenols from Pomegranate ( Punica granatum )
Pomegranate (Punica granatum) is an important fruit for direct consumption and for juice extraction. The peel of pomegranate (pomegranate peel) constitutes more than 40% of the fruit and is a
Antioxidant activity of extract of Rhus oxyacantha root cortex.
Results suggested antioxidant property of root extract of Rhus oxyacantha which could be ascribed to its free radical scavenging nature and prevented DDT-induced thymocytes death in a dose-dependent manner.
Absence of pomegranate ellagitannins in the majority of commercial Pomegranate extracts: implications for standardization and quality control.
To compare the phytochemical contents and antioxidant activities of commercially available pomegranate extract dietary supplements beyond their content of ellagic acid, a total of 27 different supplements in the form of capsules, tablets, and soft gels were studied.
Total Phenolic Contents and Antioxidant Activity of Pomegranate (Punica granatum L.) Peel Extracts
The phenolic compounds of pomegranate (Punica granatum L.) peel extracted by two methods (solvent and ultrasound-assisted) with five solvents (acetone, methanol, ethanol, water and ethyl acetate)
Evaluation of Egyptian pomegranate cultivars for antioxidant activity, phenolic and flavonoid contents
Aim The aim of the present study was to evaluate total phenolic and flavonoid contents as well as antioxidant activity of the peel, juice and seed extracts of pomegranate fruit from different
Pomegranates are widely researched fruits for their nutritional and health benefits as well as their organoleptic properties. Pomegranate juices are rich in vitamins, minerals and phytochemicals. In
Antioxidant capacities of phenolic compounds and tocopherols from Tunisian pomegranate (Punica granatum) fruits.
The antioxidant potency of pomegranate extracts was correlated with their phenolic compound content and the results implied that bioactive compounds from the peel might be potential resources for the development of antioxidant function dietary food.


Tannins in wood: comparison of different estimation methods
In the case of proanthocyanidins, reaction with vanillin in the presence of sulfuric acid is more sensitive than estimation by anthocyanidin formation. It is more specific than the assay by
Colorimetry of Total Phenolics with Phosphomolybdic-Phosphotungstic Acid Reagents
Several details of the assay of total phenolic substances have been investigated and an improved procedure developed. The improvements include the use of Folin-Ciocalteu reagent rather than the
HPLC Analysis of Gallic and Ellagic Acids in European Oakwood (Quercus robur L.) and Eucalyptus (Eucalyptus globulus)
We have studied the efficiency of analytical procedures for two phenolic compounds found in Eucalyptus globulus and Quercus robur L.: gallic and ellagic acid. Isochratic HPLC was used s a mean of
Tannins and related compounds. XL: Revision of the structures of punicalin and punicalagin, and isolation and characterization of 2-O-galloylpunicalin from the bark of Punica granatum L.
The structures of punicalin and punicalagin, isolated from the bark of Punica granatum L. (pomegranate), have been revised to 4, 6-(S, S)-gallagyl-D-glucose (1) and 2, 3-(S)-hexahydroxy-diphenoyl-4,
Plant proanthocyanidins. Part I. Introduction; the isolation, structure, and distribution in nature of plant procyanidins
The isolation and determination of structure of some plant procyanidins in their free phenolic forms are described. The distribution of procyanidins in the tissues of twenty-nine plant species has
