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. [2]
