P. Nabais, J. Oliveira, F. Pina, N. Teixeira, V. de Freitas, N. F. Brás, A. Clemente, M. Rangel, A. M. S. >The molecular structure of the medieval watercolor known as folium has finally been solved in the 21st century. The interdisciplinary approach taken was the key >following medieval instructions >multi-analytical characterization of its structure was made using HPLC-DAD-MS, GC-MS, NMR (1H, 13C, COSY, HSQC, HMBC, INADEQUATE), and computational studies. Sometimes that's what it takes to build some momentum with technical innovations over a millennium. But then you can come up with conclusions like this: >In conclusion, chrozophoridin was used in ancient times to make a beautiful blue dye for painting, and it is neither an anthocyanin — found in many blue flowers and fruits — nor indigo, the most stable natural blue dye. It turns out to be in a class of its own. Thus, we believe that this will be not our final word on this amazing plant and its story and that further discoveries will follow soon. I like that last part, >this will be not our final word >further discoveries will follow soon. That's the kind of confidence and momentum too few workers will ever achieve, and in this case looks scientifically legitimate to me.
