Introduction. The article presents information about the chemical composition and biological activity of the birch fungus – chaga (Inonotus obliquus). The biological activity of chaga is provided by its main components: polysaccharides, polyphenols, triterpenes, melanin, etc. A number of studies are presented that prove the antiproliferative, antiviral, immunomodulatory, antioxidant, neuroprotective activity of the biologically active substances of chaga. Information is presented with various methods for obtaining chaga extract. The biological active additive based on the extract of birch fungus (chaga) – "BioChaga", produced according to the original technology, by the Irkutsk company LLC "SibPribor" under the trademark "Baikal Legend" is considered. The high quality of the described biologically active additive "BioChaga" is due to the combination of environmentally friendly, rich in biologically active substances, medicinal plant raw materials of the chaga of the Baikal region and the author's technology for its processing. As a result of circulating extraction followed by lyophilization of the extract, an instant dry extract of chaga with a low density and high biological activity was obtained. Conclusion. The information presented in the article on the composition of biologically active substances, their activity, as well as the technology for obtaining chaga extract indicates the prospects for using birch fungus (Inonotus obliquus) as a source for obtaining medicines and biologically active additives.
