  Phytochemicals have received much recent attention in cancer prevention through simultaneous targeting multiple pathways in the disease progression. Here we determined that wolfberry phytochemicals was chemopreventive on the leukemic Jurkat cell. The water soluble wolfberry fractions (i.e., wolfberry phytochemicals) were enriched in carbohydrates (73.4 ± 4.5 % (w/w)), polyphenolics (1555 ± 112 mg quercetin equivalent / 100 g freeze dry powder, including 213 mg rutin/100 g freeze dry powder), and had enhanced antioxidant activity (7771 ±207 μM Trolox equivalent/ 100 g freeze dry powder). Wolfberry phytochemicals, but not purified wolfberry polysaccharide fractions, inhibited Jurkat cell proliferation, induced cycle arrest at the G2/M phase in a dose dependent manner starting at 1 mg/ml for 48 h. Wolfberry phytochemicals eliminated cellular reactive oxygen specie.. View More»
