| Popis: | espanolEl jugo de vainilla ha mostrado tener empiricamente actividad antifungica contra algunas cepas de hongos; sin embargo, no se tiene reportes contra el genero Alternaria. En este trabajo, se obtuvo el perfil quimico del jugo de vainilla y se probo su actividad antifungica contra cepas de hongos de la familia Pleosporaceae, aisladas de plantas enfermas de sorgo y cebada. Las cepas fueron identificadas como Alternaria alternata por sus caracteristicas morfologicas y moleculares. La caracterizacion del jugo de vainilla de vainas de Vanilla planifolia mostro la presencia de vainillina, acido vainillico, p-hidroxibenzaldehido, acido p-hidroxibenzoico, guaiacol, glucovainillina, alcohol vainillico y furfural. El jugo de vainilla tuvo un efecto fungistatico contra todas las cepas de A. alternata probadas en este estudio, aumento el tiempo de latencia de 50 a 112 h, y no se produjeron conidios. Este resultado indica la posible aplicacion del jugo de vainilla como una alternativa para controlar cultivos agricolas como la cebada y el sorgo en Mexico. EnglishVanilla juice has been shown empirically to have antifungal activity against some fungal strains; however, there are no activity reported against Alternaria genre. In this work, the chemical profile of vanilla juice was obtained and its antifungal activity against fungal strains from the family Pleosporaceae, isolated from sorghum- and barley-diseased plants, was tested. The strains were identified as Alternaria alternata by their molecular and morphological characteristics. The vanilla juice characterization from Vanilla planifolia pods showed the presence of vanillin, vanillic acid, p-hydroxybenzaldehyde, p-hydroxybenzoic acid, guaiacol, glucovanillin, vanillyl alcohol, and furfural. Vanilla juice showed a fungistatic effect against all A. alternata strains tested in this study and increased the lag time from 50 to 112 h, and no conidia were produced. This result indicates the possible application of vanilla juice as an alternative to control agricultural crops such as barley and sorghum in Mexico. |
