Abstract : The salts of fatty, rosin and maleopimaric acids are decomposed by ethylenediaminetetraacetic acid in a water-methanol mixture. The various metal ions are complexed and separated from the liberated organic acids by extraction. After methylation, the mixture of liberated acids is separated by a thin-layer chromatographic procedure. The various components are eluted and determined gravimetrically. A wet chemical procedure for the determination of maleopimaric acid is also given. (Author)
