Substituent effect on the ozonation of anthraquinones was discussed. Reactivity of anthraquinones with ozone increased as greater was the electron donative property of the substituent. When the unsymmetrical anthraquinones were ozonized, the remarkable selectivity of ozone attack on the both aromatic rings was observed.

Spectral studies of some hydroxy-derivatives of anthraquinones [PDF]
The u.v., visible, and i.r. spectra of several hydroxy-anthraquinones are discussed and the bands are assigned. These bands are compared with those of anthracene and anthraquinone. The band at 207 nm.

The Direct Chlorination of Anthraquinone Oxime. The Regioselective Chlorination of Anthraquinone [PDF]
Abstract The reaction of anthraquinone oxime with chlorine in the presence or absence of a catalyst was investigated. In concentrated sulfuric acid, the direct chlorination of anthraquinone oxime takes place easily at 100 °C. The chlorination occurs selectively in the β-position in the absence of a catalyst and in the α-position in the ...

Anthraquinones and Anthraquinone Glycosides from the Roots of Cassia multijuga [PDF]
Abstract From the roots of Cassia multijuga 1:3-dihydroxy-2-methyl anthraquinone, 1:3:8-tri-hydroxy-6-methoxy-2-methyl anthraquinone, 1:8-dihydroxy-6-methoxy-2-methyl an-thraquinone-3-O-rutinoside and 1:8-dihydroxy-2-methyl anthraquinone-3-O-rutinoside have been isolated and their structures elucidated.
