| "Dragon’s blood resin is generically a complex mixture of flavanoids, exemplified by [[http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?sid=8141538|dracorubin]] and dracoic acid, their derivative chalcones and deep red aurones from which the formation of benzoic acid produced as a result of acid or alkaline hydrolysis is realised. It has long been believed that the antiseptic properties of benzoic acid have contributed to the therapeutic uses of dragon’s blood in antiquity; however, the characteristic Raman bands of benzoic acid, which include the strongest features at 794 and 1001 cm−1 do not appear in any of the resin spectra reported here. Hence, we can conclude that the amount of benzoic acid is either not detectable in the naturally harvested resins or that the benzoic acid arises from a post-harvesting treatment process which could cause the chemical scission of the flavanoids..." \\ | "Dragon’s blood resin is generically a complex mixture of flavanoids, exemplified by [[http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?sid=8141538|dracorubin]] and dracoic acid, their derivative chalcones and deep red aurones from which the formation of benzoic acid produced as a result of acid or alkaline hydrolysis is realised.

| | "Dracorhodin is a major constituent found in “Dragon's blood” resin of Daemonorops draco Willd. Blume. This natural flavylium compound is a potent pharmaceutical substance due to its biological and pharmacological activities such as antimicrobial, antiviral, antitumor and cytotoxic activity." \\ |
