Another aspect of the present invention is to obtain due to their ability to scavenge free radical and form inert the extract using all parts of the plant Quercus Infectoria, phenoxy radical intermediates. A number of epidemiological preferably from the galls. studies have Suggested that consumption of polyphenol-rich 0019. Yet another aspect of the present invention is to foods reduces the risk of developing chronic diseases. obtain a herbal composition comprising antioxidant rich 0006 Although, these polyphenol antioxidants reported extract of Quercus Infectoria, wherein the antioxidant is pref for the prevention of various lifestyle diseases but only a few erably methyl gallate. findings show that they are active and majority of the results 0020 Still another aspect of the present invention is to show that they have no clinical efficacy. The vast literature on obtain the extract of Ouercus Infectoria employing solvents antioxidants Suggests that the failure of polyphenol antioxi selected from non-polar hydrocarbon, chlorinated Solvents, dant in clinical cases because it is almost impossible to elimi an ester and ketones, an alcohol and water, preferably, nate many active oxygen species produced in the body by selected from hexane, chloroform, ethyl acetate, acetone, single antioxidant molecule. methanol or ethyl alcohol. 0007 Polyphenol antioxidants derived from the plant ori 0021. Yet another aspect of the present invention is to gin have structurally phenol group as backbone and make it obtain the extract of the said herbal composition employing more lipid soluble. The bioavailability of these plant polyphe methanol with hexane and acetone preferably in 1:1 ratio, nols is very low in GI tract and therefore most of these wherein the said extract is characterized by having antioxi antioxidants have not sufficiently displayed efficacy in the dant concentration of more than 80%. body even though they have been reported as potent antioxi 0022. Still another aspect of the present invention is to dants in vitro. obtain the extract of the said herbal composition employing 0008 To overcome the above said difficulties in the prepa methanol with chloroform and methanol preferably in 1:1 ration of antioxidant composition that is effective both in ratio, wherein said extract is characterized by having phenolic vitro and clinical, it is necessary to select a group of polyphe compounds concentration of more than about 108 w/w nolic compounds rich composition that is selectively address 0023.
