The data will be acquired in the closing months of the current project. Data processing, analysis and formal reporting will follow as time permits. Phase II will be a combination of literature researching and empiracal research using the generic HPLC-esi(+) MS method to analyze the DHPA (and N-oxide) content of the commercially obtained Petasistes spp. Phase III will include large quantities of powdered Petasites spp being extracted and the processing of DHPAs. Phase IV will include the initial application of the generic HPLC-esi(+) MS analytical method to determine the need for modifications and to enhance the resolution and detection of the analytes. This method will be validated and applied to commercial Petasites-dervied dietary supplement products.
