摘　　要：维生素B6(VB6)是一类吡啶化合物的总称。以组培烟草为材料,采用高效液相色谱结合荧光检测技术,分析紫外线、低温、盐和弱光胁迫对烟草体内VB6各存在形态含量的影响。结果表明:逆境条件下,VB6各存在形态含量发生变化,其中以磷酸吡哆醛和吡哆醇含量升高最明显。Vitamin B6（VB6）is the general term for a kind of pyridine compounds. The paper aims to study the changes of the existing forms of vitamin B6 in response to abiotic stress. In this experiment, the influence of UV-B, chilling, salt and weak light stress on the content of the existing forms of VB6 in tobacco plants was determined using HPLC with fluorescence detector. The results showed that in response to abiotic stress, the content of the existing forms of VB6 changed with pyridoxal 5＇-phosphate and pyridoxine increased most obviously.
