A partition chromatographic method was developed which quantitatively separates the 2 major ipecac alkaloids emetine and cephaeline. The isolated alkaloids are determined by their ultraviolet absorbance at 283 nm. The method was applied to powdered ipecac root, ipecac sirup, and ipecac fluidextract. The results obtained show good precision.
