应用超高效液相色谱-四级杆飞行时间质谱及二极管阵列联用技术对唐代纺织品上植物染料的分析和测定

Identification of indigoid dyes in natural organic pigments used in textiles of Tang Dynasty by Ultra Performance Liquid Chromatography-Quadrupole-Time of Flight-Mass Spectrometry and Diode Array Detector

中国古代纺织品印染技术在唐代得到极大发展,可用于染色的植物和染出的色彩数量均有所增加.本研究运用超高效液相色谱-四级杆飞行时间质谱联用分析(UPLC-Q-TOF-MS)和超高效液相色谱-紫外光电二极管阵列检测(UPLC-DAD)的方法对唐代纺织品所用植物染料进行了分析测定.测定结果显示,样品中红色和棕色丝线染料来源于茜草,蓝色丝线染料来源于蓝草类植物,紫色丝线由紫草染色而成.

Ancient Chinese textile dyeing technology has been greatly developed since the Tang Dynasty. The types of plant that can be used in dyeing has also increased during that period of time. In this study, Ultra Performance Liquid Chromatography-Quadrupole-Time of Flight-Mass Spectrometry（UPLC-Q-TOF-MS） and Diode Array Detector methods were used for analyzing and identifying of the dyestuff used on the two pieces of textile from the Tang Dynasty. The results show that the dyestuffs of the red and brown samples are derived from madder; the dyestuffs of the blue sample is derived from indigo, while the dyestuffs of the purple is derived from Lithospermum rythrorhizon.
