HPLC Separation of Adenosine, Cordycepin and Adenine on Newcrom AH Column

HPLC.cloud View on hplc.cloud   Due to cordycepin having a very similar structure to adenosine, it has shown to have inhibitive properties on the COVID-19 coronavirus. However, due to their similar structures, the separation of the two sugars can be challenging. Both sugars can be separated isocratically in about six minutes on the Newcrom AH mixed-mode column, which has both hydrophobic and cationic exchange properties. The mobile phase consists of acetonitrile (ACN, MeCN) and water with ammonium formate as a buffer which makes it mass-spec (MS) compatible. It can also be UV detected at 260nm.
