Malachite green metabolized into LMG. Only the cation MG is deeply colored, whereas the leuco and alcohol derivatives are not. This difference arises because only the cationic form has extended pi-delocalization, which allows the molecule to absorb visible light. The leuco form of malachite green was first prepared by Hermann Fischer in 1877 by condensing benzaldehyde and dimethylaniline in the molecular ratio 1:2 in the presence of sulfuric acid. Malachite green is traditionally used as a dye. Kilotonnes of MG and related triarylmethane dyes are produced annually for this purpose. MG is active against the oomycete "Saprolegnia", which infects fish eggs in
The Malachite Box people used to say about the lucky workers that they "knew the words" and had certain helpers. The geography is well known because it is specified in the stories. Bazhov mentions real locations such as Sysert, the Polevskoy Copper Smelting Plant, the Gumyoshevsky mine, the villages Kosoy Brod and Krasnogorka, the Ryabinovka river. Mythical creatures in "The Malachite Box" are either anthropomorphous (primarily female) or zoomorphic. The animals that appear in the stories and have zoomorphic attributes are lizards, snakes ("The Great Snake"), cranes ("Dikes of Gold"), ants ("Zhabrei's Path"), swans ("Yermak's Swans"), cats, the deer. All these creatures, with
