摘要
文章选用古代常用于染色的六种植物,针对丝织品的染色方法展开研究,扩充建立红、黄、紫色多组颜色的检测体系,最终用于鉴定出土丝织品文物上植物染料的组成成分。为解决丝织品文物丰富颜色的分析问题,文章建立了基于自建精确质量数据库的方法,使用四级杆飞行时间串联质谱(UHPLC-QTOF-MS),对植物染料的化学成分进行快速鉴定,并探究同位素模式对鉴定结果的影响,增强鉴定结果的准确度和可信性。实验结果显示,文章所建立的数据库可以解决大量出土文物的植物染料鉴定问题,对文物的修复和文化的继承都具有十分重要的意义。
Six plants which were commonly used for dyeing in ancient times were chosen to study the dyeing method of silk fabrics,and red,yellow and purple testing system was established to identify the compositions of plant dyes on the unearthed silk fabric relics. To solve the problem of rich color analysis of silk fabric relics,the precise quality database was established,and UHPLC-QTOF-MS was used to fast identify the chemical compositions of plant dyes.Meanwhile,the influence of isotope mode on the identification result was explored to enhance the accuracy and credibility of identification results. The experimental results showed that the database established in this study could solve the problem of plant dyes identification on unearthed cultural relics,which is of great significance to the restoration and inheritance of cultural relics.
