Investigation of Asian Dyes and Pigments from the Artifact of “Murongzhi” and the Silk Road in China

[Image: see text] In this paper, a series of modern analysis methods, including Raman spectroscopy, X-ray diffraction, UV–vis spectrophotometry, and ultra-high-pressure liquid chromatography coupled with a thermoelectric LTQ-Orbitrap XL ETD mass spectrometer (UHPLC-MS/MS), were applied to analyze and accurately identify the chemical composition of plant dyes and the mineral pigment from the samples collected from grave goods. As a result, the textiles were dyed by the madder, Kermes, Phellodendron chinense, indigo, Lithospermum L., and so forth. In addition, the mineral pigment, charcoal, hematite, minium, cinnabar, azurite, and malachite were used to paint the exquisite artifacts in the tomb of Murongzhi. This research demonstrates the profound impact on cultural transmission and fusion in the “Tuyuhong” dynasty and explores the Silk Road in Tang dynasty.
