Flavonoids in the grasses (Poaceae family), Arthraxon hispidus (Thunb.) Makino and Miscanthus tinctorius (Steudel) Hackel have long histories of use for producing yellow dyes in Japan and China, but up to now there have been no analytical procedures for characterizing the dye components in textiles dyed with these materials. LC-MS analysis of plant material and of silk dyed with extracts of these plants shows the presence, primarily, of flavonoid C-glycosides, three of which have been tentatively identified as luteolin 8-C-rhamnoside, apigenin 8-C-rhamnoside and luteolin 8-C-(4-ketorhamnoside). Two of these compounds, luteolin 8-C-rhamnoside (M = 432), apigenin 8-C-rhamnoside (M = 416), along with the previously known tricin (M = 330) and several other flavonoids that appear in varying amounts, serve as unique markers for identifying A. hispidus and M. tinctorius as the source of yellow dyes in textiles. Using this information, we have been able to identify grass-derived dyes in Japanese textiles dated to the Nara and Heian periods. However, due to the high variability in the amounts of various flavonoid components, our goal of distinguishing between the two plant sources remains elusive. (C) 2011 Elsevier B.V.
