Plumbagin (5-Hydroxy-2-methyl-1,4-naphthoquinone) is a plant-derived naphthoquinone possessing a number of pharmacological activities.
A yellow pigment. antimicrobial activity. In animals, it has antimalarial, anticarcinogenic, cardiotonic, antifertilityaction, and anti-atherosclerosis effects.
Plumbagin is named after the plant genus Plumbago, from which it was originally isolated.
