摘要：采用體外抗氧化體系研究五葉地錦（Parthenocissus quinquefolia）果實(shí)多糖、花色苷對(duì)超氧自由基、羥基自由基、DPPH自由基的清除能力，采用MTT法研究果實(shí)中花色苷和多糖對(duì)兩種肝癌細(xì)胞（HepG2，SMMC-7221）的抑制作用。結(jié)果表明，多糖和花色苷濃度與肝癌細(xì)胞的抑制率具有劑量依賴關(guān)系，當(dāng)花色苷濃度達(dá)到0.312 5 mg/mL時(shí)，對(duì)兩種肝癌細(xì)胞的抑制率分別為37.89%±1.74%、53.57%±1.72%;當(dāng)多糖提取液濃度達(dá)到0.312 5 mg/mL時(shí)，對(duì)兩種肝癌細(xì)胞的抑制率分別為79.59%±0.52%、58.85%±1.12%;多糖、花色苷濃度在0.80 mg/mL時(shí)對(duì)超氧自由基的清除率分別達(dá)到74.21%±2.48%、90.06%±0.86%;對(duì)羥基自由基的清除率達(dá)到75.87%±1.61%、68.60%±1.52%;對(duì)DPPH自由基的清除率達(dá)到91.41%±0.74%、90.73%±0.44%。另外，羥基自由基、超氧自由基清除能力與抗腫瘤之間顯示相關(guān)性，與DPPH相關(guān)性較差。五葉地錦果實(shí)中提取的多糖和花色苷對(duì)肝癌細(xì)胞具有一定抑制作用，同時(shí)表現(xiàn)出好的抗氧化能力，且兩者之間存在明顯相關(guān)性，具有開發(fā)潛力。

Abstract： In vitro the antioxidant activity of polysaccharide and anthocyanin on Parthenocissus quinquefolia fruit was discussed. Study on the scavenging ability of polysaccharide and anthocyanin with superoxide free radical， hydroxyl radical and DPPH free radical. Using MTT method to study the anthocyanins and polysaccharides in inhibition of 2 kinds of hepatoma cells（HepG2， SMMC-7221）. The results showed that the polysaccharide and anthocyanin concentration has a dose-dependent relationship with the HCC inhibitory rate， when the anthocyanin concentration reached 0.312 5 mg/mL， the inhibition rate of two HCC was 37.89%±1.74%， 53.57%±1.72%; when the polysaccharide concentration reached 0.312 5 mg/mL， the inhibition rate of two HCC cells was 79.59%±0.52%， 58.85%±1.12%. The polysaccharide or anthocyanin was 0.80 mg/mL， the scavenging rate of superoxide radicals was 74.21%±2.48%、90.06%±0.86%， the hydroxyl radical was 75.87%±1.61%、68.60%±1.52%， the scavenging rate of DPPH was 91.41%±0.74%、90.73%±0.44%. Furthermore，the scavenging ability of hydroxyl radical has a correlation with antitumor. The superoxide radicals also showed certain correlation， and the correlation of DPPH was poor. Parthenocissus quinquefolia fruit polysaccharide and anthocyanin has certain inhibitory effect on HCC and radical， there is a clear correlation with antioxidant and antitumor;it has the development potential.
