为了检测杨梅的抗突变作用，以小鼠骨髓嗜多染红细胞微核为指标，检测了新鲜杨梅果汁对亚硝酸钠和Ｎ－甲基苄胺致微核突变的抑制作用。结果表明，杨梅果汁能显著地抑制亚硝酸钠和Ｎ－甲基苄胺的致突变作用
In order to detect the anti-mutagenicity of red bayberry, the micronuclei of polychromatic erythrocytes in bone marrow were used as indicators to test the inhibitory effect of fresh bayberry juice on micronucleus mutations induced by sodium nitrite and N-methylbenzylamine. The results showed that Yangmei juice can significantly inhibit the mutagenic effect of sodium nitrite and N-methylbenzylamine
