N-methylnicotinamide is a metabolite of niacin (or nicotinamide) and is commonly found in human urine. However low levels of urinary excretion of N-methylnicotinamide indicates niacin deficiency. In patients with liver cirrhosis nicotinamide methylation is increased leading to a rise in urinary N-methylnicotinamide. N-methylnicotinamide has been found to be a microbial metabolite.

Anemarrhenasaponin Ia, an useful anti-inflammation reagent, is isolated from Anemarrhenae rhizome. Anemarrhenasaponin Ia inhibits the generation of N-formyl-methionyl-leucyl-phenylalanine (fMLP)-induced superoxide.
