✦ Synopsis

Koninklijk Instituut voor het Kunstpatrimonium B-1040 Brussel, Belgium zummary. Flavokermesic acid, a minor dye constituent isolated from Kermes insects, was identified as l-methyl-3,6,8-trihydroxy-9,10-anthracene dione-2-carboxylic acid (synonym for laccaic acid D or xanthokermesic acid).

In earlier reviews, flavokermesic acid was mentioned as a dyestuff accompanying kermesic acid in extracts of insects referred to as Kermes ilicis. This shield-louse species belongs to the family of the Kermesidae (1,2); it lives on the Ilex tree in Mediterranean countries.
