@article{1Ibrahim,_H._Sani_Aliero_yakubu_2011, title={Volatile metabolites profiling to discriminate diseases of tomato fruits inoculated with three toxigenic fungal pathogens}, volume={2}, url={https://www.updatepublishing.com/journal/index.php/rib/article/view/2354}, abstractNote={The volatile metabolites of tomato fruits inoculated with three toxigenic fungi isolated from spoilt tomatoes were profiled using gas  chromatography/mass spectrometry. Differences in the number and  amount of volatile metabolites were observed. The study yielded a total of 52 different volatile metabolites. Healthy ripe tomato fruits yielded  twenty-eight metabolites predominated among them were oleic acid amide (10.89%), 9-octadecenoic acid (9.83%), methyl cis-9-octadecenoate (7.73%), and the least was 2, 3-Heptanedione (0.32%). Tomato fruits inoculated with <em>A. niger </em>yielded 11; <em>A. flavus </em>yielded 15 different volatile metabolites while that inoculated with <em>F. oxysporum </em>yielded 8 volatile  metabolites. Among them only 5 volatile metabolite occurred relatively consistent in fruits inoculated with <em>A. niger</em> and <em>A. flavus</em> while adogen 73  and 9-Octadecenoic acid (Z) occurred relatively consistently in fruits  inoculated with the three fungi. Hexadecanoic acid and 6-Methyl-2,4-di - tert - butyl – phenol was common in fruits inoculated with <em>F. oxysporum</em> and <em>A. niger</em> with that of <em>A. niger</em> having the highest value (9.67%) for Hexadecanoic acid while fruits inoculated with <em>F. oxysporum </em>had highest (2.66%) for 6-Methyl-2,4-di - tert - butyl – phenol. Ten metabolites were  unique to <em>A. flavus</em> while <em>A. niger</em> and <em>F. oxysporum</em> had 4 metabolites unique to each of them. This study suggests that these unique metabolites can be used as biomarkers to detect tomato diseases/pathogen or toxigenic fungi at an early stage of disease progression and to manage tomato diseases in storage and outbreak of food borne disease, after further validation under commercial conditions.}, number={3}, journal={Research in Biotechnology}, author={1Ibrahim, A.D. and H., Hussaini, and Sani, A. and Aliero, A.A. and yakubu, S.
