| 摘 要： | 对甜荞(Fagopyrum esculentum Moench)苯丙烷次生代谢受紫外线B辐射的响应进行了研究.结果表明:不仅卢丁、槲皮素等黄酮类化合物含量在紫外线B辐射下显著升高,而且叶片苯丙烷单环酚类化合物,如阿魏酸含量等也大幅度升高,两类化合物的应激提高对甜荞的UV-B胁迫提供了重要的保护作用.

| Abstract: | The effects of ultraviolet B(UV-B) radiation on the phenylpropanoid compounds in common buckwheat(Fagopyrum esculentum Moench) herb were studied by HPLC method.The results showed that not only the contents of flavonoid compounds,such as rutin and quercetin, were significantly increased,but also those of phenolic compounds,eg.ferulic acid and P-coumaric acid,were markedly enhanced.The enhancements of two kinds of compounds provided important protection against UV-B injury in buckwheat herbs. |
