Chrysophanic acid Usage And Synthesis
  • Chemical Propertiesyellow crystalline solid or brown powder
  • UsesChrysophanic acid, a natural anthraquinone, is used to study anticancer activity in EGFR-overexpressing SNU-C5 human colon cancer cells 1. It is also used to study the inhibition of replication of poliovirus types 2 and 3 (Picornaviridae) in vitro 2.
  • Usesantineoplastic, antibacterial
  • UsesA topical ointment used in the treatment of dermal conditions such as eczema and herpes.
  • DefinitionChEBI: A trihydroxyanthraquinone that is chrysazin with a methyl substituent at C-3. It has been isolated from Aloe vera and exhibits antiviral and anti-inflammatory activity.
  • Synthesis Reference(s)Tetrahedron Letters, 20, p. 4911, 1979 DOI: 10.1016/S0040-4039(01)86747-2
  • General DescriptionGolden yellow plates or brown powder. Melting point 196°C. Slightly soluble in water. Pale yellow aqueous solutions turn red on addition of alkali. Solutions in concentrated sulfuric acid are red.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity ProfileChrysophanic acid is incompatible with strong oxidizing agents.
  • Fire HazardFlash point data for Chrysophanic acid are not available; however, Chrysophanic acid is probably combustible.
  • Purification MethodsCrystallise chrysophanic acid from EtOH or *benzene and has m 195.6-196.2o, after sublimation it in a vacuum. The yellow mono-acetate has m 188-190o (from MeOH or Me2CO). It forms Ni2+, Co2+ and Cu2+ complexes. [Beilstein 8 H 470, 8 I 725, 8 II 510, 8 III 3808, 8 IV 3277.]
