Description and Uses
The matured fruit of Couroupita guianensis yields two highly unsaturated alkaloids. Couroupitine A is obtained in the form of yellow needles when crystallized from MeOH-CHCI3. It gives an ultraivolet spectrum with absorption maxima at 225 and 251 nm and an inflexion at 315 nm in EtOH.
Tryptanthrin is natural alkaloid, and a potent inhibitor of cyclooxygenase COX-2 and 5-lipoxygenase acting as an anti-inflammatory agent.
