ZUSAMMENFASSUNG

Preparations of Harpagophytum procumbens and of Salix species are successfully used for the treatment of degenerative rheumatism and painful arthrosis. For the quality control of both drugs, rapid methods of quantification are desirable. Here we report the development of two HPTLC methods enabling the determination of harpagoside in Harpagophyti radix and of salicin in Salicis cortex. We focused on a standardized methodology and thorough validation including two laboratories. The methods allow the analyses of up to 16 samples in parallel demonstrating the proposed methods as very rapid and cost efficient.
