Mugineic acid is the organic compound consisting of a azetidine group and three carboxylates. A colorless solid, it is a siderophore. More specifically, it is a phytosiderophore, i.e. a plant-produced siderophore. It functions as an iron accumulating agent for barley and other plants. Related phytosiderophores include nicotianamine and avenic acid.^[1]

Structure of Co(III) complex of tetra-deprotonated mugineic acid (as sodium salt, not shown).^[2]^[3]

It is biosynthesized from S-methylmethionine. The compound binds metal ions as a hexadentate ligand.^[4]
