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 Furthermore, Pavel Bazhov indicated that his stories can be divided into two groups based on tone: "child-toned" (e.g. "The Fire-Fairy", "Silver Hoof"), and "adult-toned" ("The Stone Flower", "Marko's Hill"). Denis Zherdev divided the stories into "gold" and "malachite" series, which begin with "Beloved Name" and "The Mistress of the Copper Mountain" respectively. In the mid-1930s Sverdlovsk Publishing House decided to publish the collection "Prerevolutionary Folklore of the Urals" (). In the summer of 1934 the folklorist Vladimir Biryukov was offered to make such a collection. The historian Andrey Ladeyshchikov became its chief editor. From August to December 1935 Biryukov collected
