Biological Activity
Melatonin-OH (Cyclic 3-hydroxymelatonin) (3COHM) (5 μg/mL) can be accurately detected and quantified via optimized HPLC, with a measured concentration of 4.93 μg/mL for a 5 μg/mL standard solution and a retention time of 8.1 min with excellent peak resolution[1].
Cyclic 3-hydroxymelatonin (3COHM) (5 μg/mL) can be detected and quantified via optimized MEKC, with a measured concentration of 4.70 μg/mL for a 5 μg/mL standard solution, though results differ significantly from HPLC measurements[1].
