摘要
卷烟烟气会导致鼠肺细胞膜脂质过氧化损伤。采用适当的方法将茶多酚添加到卷烟中,能有效地抑制烟气引发的鼠肺细胞膜脂质过氧化水平,抑制率可达30%～40%,抑制效果优于维生素C和维生素E,且抑制作用的稳定性较好。实验还证明了把纳米SiO2与茶多酚溶液经超声波处理后再添加到卷烟中,其抑制烟气对鼠肺细胞膜脂质过氧化损伤效果更佳。
Cigarette smok has markedly induced lipid peroxidation in rat lung cell suspension. However, smoke produced by cigarettes that were processed with green tea polyphenols (GTP) has showed a reduced damage to rat lung cell membranes,This result suggested that GTP added into cigarette could significantly inhibit lipid peroxidation induced by cigarette smoke through scavenging free radicals. GTP could inhibit lipid peroxidation by 30% ? 40% , which was better than that of vitamin C or E.If GTP was also added into cigarettes in combination with nano SiO2, the result showed that this combination was superior to the inhibition of lipid peroxidation induced by cigarette smoke.
