Grape skin and seeds are sources for phenolic compounds that contribute to the sensory characteristics and beneficial bioactive of many processed foods. Hence, the study was aimed to evaluate and characterize the phenolic composition and evaluate the antioxidant activities of three grape varieties skin (white, red and black) and white grape seeds. The results indicated that among the grape skin of the three varieties, black grape skin (BGS) contained the highest amount of total phenolic…

Major flavonoids in grape seeds and skins: antioxidant capacity of catechin, epicatechin, and gallic acid.

The results indicated that dimeric, trimeric, oligomersic, oligomeric, or polymeric procyanidins account for most of the superior antioxidant capacity of grape seeds.

Phenolic content and antioxidant capacity of muscadine grapes.

According to previous results, ellagic acid and not resveratrol was the major phenolic in muscadine grapes, but reported here for the first time are the phenolic content and antioxidant capacity of mus cadine leaves.

An analytical survey of the polyphenols of seeds of varieties of grape (Vitis vinifera) cultivated in Greece: implications for exploitation as a source of value-added phytochemicals.

The predominant flavanol monomer in white and red varieties was catechin (which accounted for 50.5 and 49.3%, respectively, of the total content), whilst gallic acid and epigallocatechin were the constituents showing the lowest content, respectively.
