A novel purple-red pigment from the plant genus of Allium (onions, leeks), subgenus Melanocrommyum (drumstick onions), is described. Because this pigment, which reminds blood, some species are used in Southwest and Central Asia as herbal medications, spices or vegetables. proposal for formation structure provided, first example a tetrathiaporphyrin nature. The described substance shows low stab...

Carbon nanostructures offer a perfect link between nanoscale materials and organic molecules, making them an ideal platform for molecular catalysts. Herein, efficient, straightforward, high-yield synthetic approach is described to synthesize aryl boronic acid containing the pyrene moiety that noncovalently immobilized by π–π interaction carbon nano-onions’ surface. The nanostructured material c...

The majority of the by products formed during onion processing remain unutilized, yet they are rich in bioactive compounds and phytochemicals. Onions a very valuable vegetable. Onion chemical incredibly diverse, work through variety pharmacological mechanisms to prevent disease. Although mechanism action chemicals found onions has been studied, there is still room for further reformulating nutr...
