HPLC Method for Epibatidine on Primesep 200 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Epibatidine
Epibatidine is an alkaloid with the chemical formula C11H13ClN3. It is secreted by the Ecuadorian frog commonly known as Anthony’s Poison Arrow frog from the genus of poison dart frogs, Ameerega. It’s existence in nature is still debated due to limited samples that were collected by John W. Daly, and even fewer samples that were still left when high resolution spectrometry was popularized and used on the compound. As a poison, Epibatidine causes full body numbness which can progress into full body paralysis and respiratory arrest. Due to it’s high toxicity, it is not used as a drug, despite the analgesic effect. You can find detailed UV spectra of Epibatidine and information about its various lambda maxima by visiting the following link.
Epibatidine can be retained and analyzed using the Primesep 200 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a sulfuric acid buffer. Detection is performed using UV.

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.
