| Sumario: | Plants have developed a variety of protection mechanismswhich include the synthesis of both, low molecular weight secondarymetabolites and macromolecules as proteins and peptides withantimicrobial activity. There are previous reports of antifungal peptidesfound on the seeds of other Amaranthus species, so it is veryprobable that these kind of compounds are present in the A.hypochondriacus seeds. This was confirmed by the antifungal activityof a protean extract from A. hypochondricus against such pathogenicfungi as Alternaria alternata, Fusarium solani, Candida albicans,Fusarium oxysporum, Trichoderma sp. and Aspergillus ochraceus.The fungal growth inhibition was evaluated using the poisonedagar and the microspectrophotometry tests. |
