A dye for cells and tissues from Papaver rhoeas, comprising a new bioflavonoid, specifically staining the nucleus used for microscopic evaluation in histopathology, microbiology and cytology, is compiled. Apparently, it is an alternative to hematoxylin in routine use. The biochemical name of this compound is tetrahydro-3,4,5-trihydroxy-6-methyl-2H-pyran-2-yloxy) methyl) 2H-pyran-2,3,4,5-tetraol) -4-methoxyphenyl) -7 methoxy-4H-chromen-4-one. The NMR analysis showed that the biochemical structure of the molecule is a bioflavonoid (Fig. 4, 5). A molecule from Papaver rhoeas, along with synergistic and other molecules, penetrates into biological and non-biological samples. When combined with other synergistic mechanisms, the composition of the dye is obtained. The amount and type of dressing and pH are parameters that affect the quality and time of staining. The composition of Papaver rhoeas is obtained, in particular, for tissue research for diagnosis in laboratories and hospitals, and it is intended for routine use. Millions of biological samples from all over the world are exploring, such as those obtained during surgery and biological products that are samples stained for diagnosis. Dye for hematoxylin tissues is used routinely and is obtained from trees called Hematoxylin campechianum (logwood), which is part of the world's tropical forests. Each year, 3,000 logs, as well as plots, are cut down to produce approximately 1,200 tons of powder and 70,000 tons of liquid dye hematoxylin ($ 15 billion / year). The composition of Papaver rhoeas provides effective and specific staining, allowing you to select the core. In addition to the obvious economic benefits, Papaver rhoeas is widespread and can be easily collected and received. The composition of Papaver rhoeas also has an environmental impact on the Earth, which allows it to be an important and useful industrial product.Составляют краситель для клеток и тканей из Papaver rhoeas, включающий новый биофлавоноид, специф
