Microbial contamination is the most important cause of losses in plant tissue culture, therefore various synthetic and toxic compounds are used to counteract this problema: However, there are species such as Melia azedarach L. which have antimicrobial, insecticidal and nematicides properties that could be an ecological alternative. The present work studied the disinfecting effect of the ethanolic extract of leaves of Melia azedarach L. in garlic bulbs. It was found that in the treatments HgCl 0.1% (Control 1), Extract of Melia – H2O (1:1), Extract of Melia – EtOH 70% (1:1), Extract of Melia and EtOH 70% (Control 2) were statistically equal with an asepsis of 100%, 100%, 95%, 90% and 85% respectively, and superior to Extract of Melia – H2O (1:9) with 35% asepsis, evidencing the disinfecting power of the extract of melia in tissue culture. The treatment with the lowest concentration of the initial extract, Extract of Melia – H2O (1:9), had the highest percentage of contamination (65%), also presenting all the pathogens found in the other treatments such as fungi of the genus Penicillium, Fusarium and Aspergillus and Gram-negative and Grampositive bacteria. A non-directed metabolomic analysis was carried out on Extract of Melia - H2O (1:1) and Extract of Melia – EtOH 70% (1:1) identifying 100 metabolites, of these the 17 compounds that exceed 25E+06 in abundance relative in at least one of the extracts were chosen. Finding the antibiotic and antifungal (Chalcone) and the fungicides (Phacidin and Terbinafine). All this shows the great potential of secondary metabolites and opens a great opportunity for Peru to exploit its plant diversity to give it added value.
