Korean raspberry, Rubus coreanus Miquel (RCM), contains high concentrations of phenolic compounds, which prevent oxidative stress. To determine the effect of RCM on antioxidant capacity in humans, we assessed in vivo lipid oxidation and antioxidant enzyme activities from plasma in 15 healthy men. The subjects ingested 30 g of freeze-dried RCM daily for 4 weeks. Blood was taken at baseline and at the end of the study to determine blood lipid profiles, fasting plasma glucose, liver function, lipid peroxidation, and antioxidant enzyme activities. RCM supplementation had no effect on blood lipid or fasting plasma glucose concentrations but decreased alkaline phosphatase activity. RCM supplementation increased glutathione peroxidase activities (P < 0.05) but had no effect on lipid peroxidation. These results suggest that short-term RCM supplementation may offer health benefits by enhancing antioxidant capacity in a healthy population.
韩国覆盆子,Rubus coreanus Miquel(RCM),含有高浓度的酚类化合物,可防止氧化应激。为了确定 RCM 对人体抗氧化能力的影响,我们评估了 15 名健康男性体内的血浆脂质氧化和抗氧化酶活性。受试者每天摄入 30 克冻干 RCM,持续 4 周。在基线和研究结束时采集血液,以确定血脂谱、空腹血糖、肝功能、脂质过氧化和抗氧化酶活性。RCM 补充剂对血脂或空腹血糖浓度没有影响,但降低了碱性磷酸酶活性。RCM 补充剂增加了谷胱甘肽过氧化物酶活性(P<0.05),但对脂质过氧化没有影响。这些结果表明,短期 RCM 补充可能通过增强健康人群的抗氧化能力带来健康益处。
