【摘要】 采用哺乳动物细胞诱发基因突变试验，研究了魁蜜种和ＦｒｕｉｔｉｎｇＭａｌｅ种猕猴桃汁对Ｎ—甲基—Ｎ’—硝基—Ｎ—亚硝基胍（ＭＮＮＧ）诱发ｇ１２细胞ｇｐｔ位点突变的拮抗作用。结果表明，两种猕猴桃汁对ＭＮ－ＮＧ的诱变性都有显著的抑制作用，进一步说明了猕猴桃抗损伤作用的广谱性，同时发现猕猴桃汁的活性成分是在细胞内发生作用的。更多还原

【Abstract】 Antimutagenicity of the two kinds of kiwi fruit(KF) was studied with 6-thioguanine-resistant mutation assay.The results showed that both Kuimi and Fruiting Male KF could significantly reduce the frequency of 6-thioguanine-resistant mutants induced in g12 cell line by MNNG,and the suppressing effects of KF functioned within cells.更多还原
