嘎拉和金冠中多酚化合物种类不同，已知嘎拉果皮中含有花青素-山越橘苷，而金冠中没有；本实验发现金冠果肉中含有槲皮苷，而嘎拉果肉中没有检测到。

College of Animal Sciences, Zhejiang University, Hangzhou 310029, ChinaAbstract: In vitro chicken embryo hepatocytes were adopted to evaluate the antioxidizing effects of vitamin E and quercetin on polychlorinated biphenyls-induced toxicity.

利用体外培养的鸡胚肝细胞研究抗氧化剂维生素E和槲皮素对多氯联苯（polychlorinated biphenyls， PCB）引起的肝细胞损伤的缓解作用。

As antioxidants, the vitamin E or quercetin (10μg/mL) significantly attenuated the toxic effects of PCBs on the cultured hepatocytes. The above results indicated that vitamin E or quercetin might antagonize the toxic effect of PCBs via antioxidizing effects on in vitro cultured chicken embryo hepatocytes.

结果表明离体培养的鸡胚肝细胞可作为肝损伤的细胞模型，PCB对培养的肝细胞的损伤及抗氧化剂维生素E和槲皮素对它的缓解作用提示， PCB对肝细胞的损伤可能是通过诱导细胞膜发生脂质过氧化而导致细胞的死亡。
