Abstract
An active natural flavanone compound: 3,7,3,4-tetrahydroxyflavanone, 3- protocatechuate obtained from the stembarks of Prosopis Africana, tested against inflammation and showed a significant anti-inflammatory activity inhibiting COX-2 and iNOS at concentration of 20mM. The structure was established on the basis of their UV, NMR (1D and 2D ) spectra, mass spectrometry and polarimeter.
