Summary of results
HPLC profile of a low temperature (~50 °C) extract of fibers from a red 19th century Chinese silk shawl showed that both carthamin (red) and berberine (yellow) dyes were detected. Carthamin was most likely come from safflower and berberine from a plant that contains alkaloids, for example amur cork tree or Chinese cork tree [2]
HPLC profile
Absorbance at 450nm (mAU) Modified HPLC profile with author's permission [2]
