Abstract
A methanolic extract of Oroxylum indicum strongly inhibited the mutagenicit y of Trp-P-1 in an Ames test. The major antimutagenic constituent was ident ified as baicalein with an IC50 value of 2.78 +/- 0.15 muM. The potent anti mutagenicity of the extract was correlated with the high content (3.95 +/- 0.43%, dry weight) of baicalein. Baicalein acted as a desmutagen since it i nhibited the N-hydroxylation of Trp-P-2.
