“…Its color does not respond to pH, unlike aurofusarin [ 8 ]. Furthermore, it has chelating properties, forming complexes with Mg 2+ , Al 3+ , Fe 3+ , Ni 2+ , and Cu 2+ in a solid state and aqueous medium [ 53 , 54 , 55 ].…”

“…Several studies mention rubrofusarin or derivatives isolated from different sources, usually fungi [ 56 ], or plant roots or seed [ 55 ], for pharmacological purposes. Ashley et al [ 8 ] published a pioneer report on the isolation of rubrofusarin from F. culmorum and F. graminearum .…”

“…Jing et al [ 62 ] found rubrofusarin glycosides to have antioxidant properties, one of which was even stronger than vitamin C. The pigment was also found to exhibit estrogenic activity [ 69 ]. Rubrofusarin bioactivity has led Moreira et al [ 55 ] to effectively demonstrate its fitness to be applied as a fluorescent probe.…”

Several studies have explored in depth the biochemistry and genetics of the pigments present in Fusarium graminearum, but there is a need to discuss their relationship with the mold’s observable surface color pattern variation throughout its lifecycle. Furthermore, they require basic cataloguing, including a description of their major features known so far. Colors are a viable alternative to size measurement in growth studies. When grown on yeast extract agar (YEA) at 25 °C, F. graminearum initially exhibits a whitish mycelium, developing into a yellow-orange mold by the sixth day and then turning into wine-red. The colors are likely due to accumulation of the golden yellow polyketide aurofusarin and the red rubrofusarin, but the carotenoid neurosporaxanthin also possibly plays a major role in the yellow or orange coloration. Torulene might contribute to red tones, but it perhaps ends up being converted into neurosporaxanthin. Culmorin is also present, but it does not contribute to the color, though it was initially isolated in pigment studies. Additionally, there is the 5-deoxybostrycoidin-based melanin, but it mostly occurs in the teleomorph’s perithecium. There is still a need to chemically quantify the pigments throughout the lifecycle, and analyze their relationships and how much each impacts F. graminearum’s surface color.

“…In these systems the polarity functions were correlated with a variety of physicochemical properties (Stokes shifts, E T N ) measured in different solvent mixtures (ethanol-water, acetonitrile-water and dioxane-water). The emission bands for coumarin derivatives [15] were blue-shifted after adding the organic solvents in system and the Stokes shifts were unusually low in mixtures with lower values for the Lippert-Mataga solvent polarity parameter. The fluorescence behavior of the systems studied in the presence of different environments is important for the characterization of the coumarin derivatives in different pharmaceutical and chemical forms.…”
