Artifact Information

A male mummy (Yingpan man) (tomb No. 5) was discovered in Yingpan, Xinjiang by archaeologists of Xinjiang Institute of Archaeology [1]. The costume mainly includes a fine red woolen robe and an embroidered trousers. The robe was made of wool. The patterns of the robe shows the character and poses of nude putti. The robe patterns also have representations of goats and cattle with pomegranate trees standing between them [2].The colors on the two objects were well-preserved due to the special (very dry) climate in Xinjiang.

Analytical instrumentation and procedures

The dye was extracted from a thread (0.2-1mg) of the archaeological object in a solution of pyridine/water/1.0M oxalic acid as described by Mouri and Laursen [2]. The solution was evaporated to dryness under a nitrogen flow, and redissolved in 50 μL MeOH/H2O (1/1); subsequently, 20 μL of dye solution was injected onto HPLC column.

An extract was analyzed on an HPLC-PDA-MS system consisting of a Shimadzu LC-20A high performance liquid chromatography, a Shimadzu SPD-M20A photodiode array detector and a Thermo LTQ XL ion trap mass spectrometer. The separation was performed on a Shim-pack XR-ODS column (3.0 mm × 75 mm, 2.2-μm particle size) and a Phenomenex Luna C18 column (2.0 mm × 150 mm, 3-μm particle size). Columns were eluted with acetonitrile-water gradients containing 0.1% formic acid at a flow rate of 0.3 mL/min.


Summary of results

The results of dye analysis for woolen robe show that red dye was probably obtained from Rubia tinctorum, whereas yellow dye was likely obtained from a luteolin-based dye source, for example, weld or desert polar tree ( Populus euphratica or "Populus_pruinosa" ).

With regard to the embroidered trousers, brown and green threads were likely dyed with Rubia tinctorum and indigo-based dye sources, respectively.
