中文摘要: 为快速鉴别不同种质宁夏枸杞化学成分的差异,采用红外光谱法对不同种质宁夏枸杞的红外光谱特征进行研究。结果表明:不同种质宁夏枸杞分别在 3 380、2 930、1 640、1 400、1 260、1 060、917、869、784、779、629 cm-1等处均有不同程度的较强红外吸收,说明不同种质宁夏枸杞的化学成分相似,但含量有所差异。聚类分析结果表明:不同种质宁夏枸杞由于化学成分的差异被分成3大类,14-16、14-17、14-107、16-23-7-8为一类,Z-44、14-4-4-13、14-401、精杞 4 号、14-26-5、宁杞 1 号为一类,14-87、宁杞 5 号、16-16-9-2、16-1-3-5、NM14-02 为一类。
Abstract:To quickly identify and evaluate the differences between chemical components of different L.barbarum L.germplasm,infrared spectroscopy was used to study the spectrum of chemical components of different L.barbarum L.germplasms.The results showed that different L.barbarum L.germplasms showed absorptions with different strength at 3 380,2 930,1 640,1 400,1 260,1 060,917,869,784,779,629 cm-1,respectively,which meant that the chemical components of different L.barbarum L.germplasms was similar but the content was different.The result of cluster analysis showed that the different L.barbarum L.germplasms were divided into three categories due to the difference of chemical components.14-16,14-17,14-107,and 16-23-7-8 were classified as a category,Z-44,14-4-4-13,14-401,Jingqi No.4,14-26-5,and Ningqi No.1 as a category,and 14-87,Ningqi No.5,16-16-9-2,16-1-3-5,and NM14-02 as a category.
