基于染料紫檀有机成分含量的指纹图谱

Fingerprint Based on the Organic Component Content of Pterocarpus Tinctorius

以赞比亚出产的染料紫檀为例,研究染料紫檀的有机成分含量,使用微波提取,气相色谱质谱联用法测定染料紫檀的有机成分组成,通过数据转换为散点图,这种图形趋势和组分含量就是染料紫檀的有机成分指纹图谱,直观地反映染料紫檀中有机成分特征。比较不同种木材有机成分指纹图谱的差别,用于鉴别染料紫檀。利用SPSS24中余玄相似性统计指纹图谱向量之间的相似度均在0.99以上,表明以这种方式构建的指纹图谱是有代表性和可信性。该方法对染料紫檀进行鉴别,有较高的有效性、可靠性和稳定性。

Taking the Pterocarpus tinctorius produced in Zambia as an example,the organic component content of the pterocarpus tinctorius was studied.The organic component composition of the pterocarpus tinctorius was determined using microwave extraction gas chromatography mass spectrometry,and the data was converted into a scatter plot.This graphical trend and component content are the organic component f ingerprint of the pterocarpus tinctorius,which intuitively reflects the characteristics of the organic components in the pterocarpus tinctorius.Compare the differences in f ingerprint spectra of organic components among different types of wood for identifying the pterocarpus tinctorius.Using the Yuxuan similarity statistics in SPSS 24,the similarity between f ingerprint map vectors is above 0.99,indicating that the f ingerprint map constructed in this way is representative and credible.This method has high effectiveness,reliability,and stability in identifying the pterocarpus tinctorius.
