摘要: A HPLC method has been developed for the simultaneous characterisation of anthraquinone glycosides and aglycones in extracts Rubia tinctorum L. The anthraquinones are separated on an end-capped C18-RP column with a water–acetonitrile gradient as eluent measured UV detection at 250 nm. With this lucidin primeveroside ruberythric acid lucidin, alizarin, purpurin, quinizarin 2,6-dihydroxyanthraquinone can be analysed. Lucidin which is not commercially available was synthesised starting from resorcinol phthalic anhydride. mixture were by droplet counter-current chromatography ascending flow chloroform–methanol–water eluents prior to their use standards.
