摘　　要：目的:磷酸吡哆醛进口标准品及合成品的比较与鉴定。方法:应用TG/DTA联用热分析仪分别对磷酸吡哆醛进口和国内合成品进行差热图谱扫描与分析。结果:进口及国内合成的磷酸吡哆醛的热谱特征一致,说明磷酸吡哆醛合成成功;其中的出峰温度、峰面积的差异是由于它们的纯度不同所致。结论:差热分析法用于对物质的鉴定,简便、快速。Objective： Comparison and identification of pyridoxal phosphate （including importation and own preparation）. Methods： TG/DTA scanning and analyse. Results： They were unanimous that characteristic thermal diagram of pyridoxal phosphate which importation and own reparation, this shows that own preparation was successful. At the same time difference that peaking temperature and the peaking area was due to their different purity. Conclusion： Differential thermal analysis method are simple and speedy for to identification of materials.
