太空育种射干的FTIR分析

对我国首创的第4代太空育种射干与地面组射干的非晶成分从整体上进行了测定和对比分析，以期为更全面地了解太空射干品质的变化和深入研究积累资料，探索建立太空射干质量标准。结果表明两组样品的FTIR谱的主要吸收峰的峰位、峰形大致相同，但峰的强度却有明显差异。与地面组相比，太空射干在1 642 cm-1处酮类的CO伸缩振动峰增强，表明太空射干中的主要活性成分异黄酮类化合物含量明显增加，在1 318 cm-1处一水草酸钙吸收峰增加，在1 541，1 456 cm-1处分子中苯环的环伸缩振动峰、1 417 cm-1处亚甲基的C—H键弯曲振动峰以及1 051 cm-1处伯醇的C—O的伸缩振动峰都明显减弱。太空诱变育种有利于筛选出活性成分含量提高的射干新品种。预期太空射干的药效比地面组的有所增强，有待于深入研究来证实。

Analysis of Belamcanda Chinensis with Space Flight Mutagenesis by FTIR

The amorphous active components of the space mutagenesis Belamcanda chinensis and the ground group were measured,compared and analyzed.The purpose was to get a comprehensive understanding of the changes in quality of the 4th generation space mutagenesis Belamcanda chinensis,accumulate data for further studies,and try to establish the quality criterions of space mutagenesis Belamcanda chinensis.The result shows that the FTIR spectra of the space sample are almost the same as that of the ground one in terms o...
