The phenomenon of Oak decline is one of worrying phenomena that has been occurred in Zagros forests, and the extent of the infected forest areas is spread increasingly. The present study aims to investigate the symptoms of Oak decline on the individuals and its effect on the secondary compounds of Quercus brantii leaves. For this purposes, three forest regions including Abolivafa, Miankouh and ...
To investigate adulteration in commercial chili powder, the volatile organic compounds of healthy and infected powdered chili pepper were characterized using a solvent-free solid injector (SFSI) coupled with gas chromatography/mass spectrometry (GC/MS). Except for one compound (capillary compound for blank), 43 compounds were identified in healthy and infected chili powder. Specifically, 31, 36...
