摘　　要：为了找到有效抑制烟草中多酚类物质氧化分解的方法，向多酚提取液中添加抗坏血酸。放置一周后发现，与不加抗坏血酸的多酚提取液相比，加入抗坏血酸的下降趋势缓和，多酚含量稳定，说明抗坏血酸能有效抑制多酚类物质的氧化分解。该研究为控制多酚氧化酶（PPO）引起的烟草的颜色变化提供了一个有效途径。多酚类化合物的含量测定采用高效液相色谱法，重现性好，回收率为95．8％～102．8％，结果可靠。Ascorbic acid was added to the extraction of polyphenols to control the oxidation of poiyphenols in tobacco. The content of polyphenols with aseorbic acid was decreased slowly after one week storage, which supplied an effective way to control the activity of polyphenol oxidese. The content of polyphenols was determined by high performance liquid chromatography, and the recovery was in the range of 95.8 -102.8%.
