A wide variety of phytochemicals, mostly flavonoids or polyphenolics, have been shown to possess anticarcinogenic activities. Among these are the grape seed proanthocyanidins (GSPs), which are the active ingredients of grape seed extract (GSE). Substantial in vitro and preclinical in vivo studies have shown the chemopreventive efficacy of GSPs against various forms of cancers in different tumor...

We have developed a novel nuclei extraction method that allows for the extraction of high molecular weight DNA from leaves of woody perennial soft-fruit species that contain high levels of carbohydrates and polyphenolics. The method utilizes a modified buffer system including 4% (w/v) polyvinylpyrrolidone (PVP)-10 and a combination of nylon filters and Percoll gradients to purify nuclei extract...
