Kermes vermilio Kermesic acid

The thin-layer chromatogram shows at first sight that the red samples of the coronation robe and of the Tunicella have been dyed with kermes (Kermococcus vermilio PLANCHON). As the comparison shows, not only the green spot of kermesic acid, but also the red spot of flavokermesic acid is clearly visible. 

Kermesic acid in Kermes from insect species such as Kermes vermilio Planchon. eaidKennococcus illicis. 

Kermesic acid is 9,10-dihydro-3,5,6,8-tetrahydroxy-l-methyl-9,10-dioxo-2-anthracenecarboxyhc acid the structure has been determined by GadgU et al. (1968). It is the principal compoimd foimd in dye extracted from the kermes insect Kermes vermilio Planchon and also, to a lesser extent, the so-called Pohsh cochineal insect Porphyrophorapolonica L. and to an even lesser extent the Armenian cochineal Porphyrophora hamelii Brandt. This consists principally of kermesic acid, although the related...
