The Ephedra Story: Automated SPE Procedure and Analysis for the Determination of Ephedra and Ephedra-like Compounds in Dietary Supplements
18 Sept 2017Ephedra is a naturally-occurring substance derived from the Chinese herb Ma Huang. Its principle active ingredient is ephedrine, which, when chemically synthesized, is regulated as a drug. In recent years, they have been extensively promoted and used to aid weight loss, enhance sports performance and increase energy. This application note presents the advantages of using an automated solid phase extraction method coupled with HPLC to determine the various levels of ephedra and ephedra-like compounds in dietary supplements versus manual solid phase extraction.

Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.

Such drugs can have mind-altering effects, with some causing dependence and addiction.Natural ProductsSolid Phase Extraction (SPE)Solid phase extraction (SPE) is a sample preparation technique used to separate and concentrate analytes from complex mixtures. It is widely used in environmental, pharmaceutical, and clinical analysis. SPE provides higher sensitivity and selectivity compared to traditional liquid-liquid extraction methods, making it essential for accurate and reproducible results.
