A new anthraquinone, viz. 1,3-dihydroxy-5,6,7-trimethoxy-2-methylanthraquinone has been synthesised by the cyclisation of 1',3'-dihydroxy-3,4,5-trimethoxy-2'-methylbenzophenone-2-carboxylic acid with sulphuric acid in presence of boric acid, and has been found to be identical with the natural sample earlier isolated from Cassia javanica roots.
