Traumatic acid is a monounsaturated dicarboxylic acid naturally occurring in plants. The compound was first isolated from wounded bean plants by American chemists James English Jr. and James Frederick Bonner and Dutch scientist Arie Jan Haagen-Smit in 1939. Traumatic acid is a potent wound healing agent in plants (\"wound hormone\") that stimulates cell division near a trauma site to form a protective callus and to heal the damaged tissue. It may also act as a growth hormone, especially in inferior plants (e.g. algae). Traumatic acid is biosynthesized in plants by non-enzymatic oxidation of traumatin (12-oxo-trans-10-dodecenoic acid), another wound hormone.
