Abstract: Fumonisins are the group of secondary metabolites produced by a fungi Fusarium verticillioides which often contaminate foods and most potent naturally occurring carcinogen. Fumonisins are highly stable molecules which are extremely difficult to remove of destroy once formed in a commodity. In the present study, to explored the potential of some indigenous medicinal plants in the detoxification of fumonisin in vitro. Of the various plants extracts tested, the methanolic extract (1%) obtained from the leaves of Lippia nodiflora (L.,) Verbenaceae showed the maximum degradation of fumonisin. The methanol extract of L.nodiflora showed significant levels of detoxification of other Fumonisins B2 also. Maximum detoxification decreased at pH7 and pH3. Time course study of fumonisin detoxification by L.nodiflora extract showed that degradation of fumonisin occurred within 10 min and the percentage of degradation gradually increased with increase in incubation time.
