A process for the preparation of hydroxyl substituted anthraquinones is described. The process couples a phthalic anhydride (substituted or unsubstituted) to benzene ring moiety substituted with at least two hydroxyl groups. Remaining hydroxy groups were converted to methoxy groups in some anthraquinones. The compounds are particularly useful for the treatment of parasitic diseases. Also, a method of treating or preventing malaria, filariasis schistosomiasis and other parasitic diseases using anthraquinones.

reported anthraquinones from daylily roots with potent activity against pathogenic trematode Schistosoma mansoni. Here we report the synthesis of novel anthraquinones A-S and their antifilrarial activity. Anthraquinones A-S were synthesized by a single-step Friedel-Craftsacylation reaction between phthalic anhydrides and substituted benzenes. The antifilarial properties of these synthetic anthraquinones were
