Sappanwood 蘇芳(suo): A red dye extracted from any of several tropical trees of the senna genus, Caesalpinia, such as C. brasiliensis (from Brazil), C. crista (from Pernambuco), C. echinata (peachwood from Nicaraugua), or C. sappan (sappanwood from East Indies and Asia). Its principal colorant is Brasilin, a hydroxyanthraquinone, that gives a deep red to brownish color when it is oxidized to form brasilein. (Do we know it's sappanwood and not the others?)
Although it has been detected, the use of sappanwood appears to have been infrequent. Due to its sensitivity to pH, sappanwood can be manipulated to produce a range of colors as pink, red, or oranges. It is unknown if printers adjusted the pH to create a range of colors. Evidence of pH manipulation is difficult to extrapolate from the prints themselves since many of the examples have discolored due to fading and/or ageing. Sappanwood usually appears as a dull pinkish brown.

Analysis
Excitation Emission Matrix (EEM) spectroscopy can easily identify the organic reds: safflower, madder, and sappanwood. Sappanwood does not fluoresces under UVA radiation and produces a unique EEM pattern....
