1863 J. Stenhouse in Proc. Royal Soc. 12 633 The colouring matter of munjeet..contains no alizarine at all, but purpurine and a beautiful orange colouring matter crystallizing in golden scales, to which I purpose giving the name of ‘munjistine’.

1883 Amer. Jrnl. Pharmacy 55 366 The madder-root contains..three glucosides, viz...a third which gives munjistin or xanthopurpurincarboxylic acid.

1937 Proc. Royal Soc. 121 549 By the reduction of purpurin-3-carboxylic acid or galiosin, its glycoside, there is formed munjistin or 2:4-dihydroxyanthraquinone-3-carboxylic acid.

1957 R. H. Thomson Naturally occurring Quinones iv. 169 [They] showed that lucidin could be oxidized..to the corresponding acid (munjistin) with alkaline silver oxide.

1998 Phytochemistry 47 315 From the hydrophilic fraction of the Chinese medicinal plant Rhynchotechum vestitum, three anthraquinones were isolated. Munjistin-1-O-methyl ether is a new compound.
