摘　　要：为了探讨桑枝抗氧化作用的物质基础,进一步开发桑枝的药用功能,采用比色法对广东桑不同品种及不同生长季节桑枝的总黄酮含量、总抗氧化活性、.OH和O2-.清除作用进行了测定,结果表明:品种和生长季节对桑枝总黄酮含量和体外抗氧化活性有显著的影响(P<0.05)。分析结果还显示:染色体倍数性对桑枝总黄酮含量和体外抗氧化活性无显著的影响(P>0.05);桑枝总黄酮含量与抗氧化活性间呈现显著的正相关关系(P<0.01)。In order to study the material base of antioxidation of mulberry branches and develop medicinal function, the flavonoid contents, T-AOC, SHRC and SSARC of mulberry branch from different varieties of Morus atropurpurea Roxb and in different growth seasons were determined by colorimetric method. It revealed that mulberry species, mulberry varieties and seasons had significant influence on total flavonoid contents and its antioxidation activity（ P 〈0.05）. The influence of chromosomes ploidy of mulberry to total fiavonoid contents and the antioxidation activity was not significant（ P 〉0.05）. The correlation between the flavonoids content and antioxidation of mulberry branch was significantly positive （P 〈0.01 ）.
