Dihydrochalkony są syntezowane przez rośliny i charakteryzują; się słodkim smakiem. Również syntetyczne związki posiadające ugrupowanie dihydrochalkonu wykazują wysokie wrażenie słodkości (Winnig M, Bufe B, Kratochwil NA, Slack JP, Meyerhof W 2007 BMC Struct. Biol. 7, 66; Krammer G, Ley J, Riess T, Haug M, Paetz S, Kindel G, Schmidtmann R. Patent No.: US 20100233102; Sep, 16, 2010. Encyclopedia of Food Science, Food Technology and Nutrition. Academic Press, London 1993, Krutosikowa A., Uher M.: Naturalne i syntetyczne substancje o słodkim smaku. PWN, Warszawa 1990; 2'-HydroksydihydrochaIkon jest wykorzystywany jako blok budulcowy w syntezie propafenonu - substancji czynnej leków przeciwarytmicznych (Noe CR, Knollmuller M, Oberhauser B, Steinbauer G, Wagner E. 1986 Chemische Berichte, 119, 729-743; Ecker G, Chiba P, Hitzler M, Schmid D, Visser K, Cordes HP, Csollei J, Seydel JK, Schaper K-J. 1996 J. Med. Chem. 39, 4767-4774; Ecker G, Noe CR, Fleischhacker W. 1997 Monatsh. Chem. 128, 53-59). Znana jest również ich aktywność względem patogennych mikroorganizmów, w tym gram-dodatnich i gram-ujemnych bakterii oraz grzybów (Awouafack MD, Kusari S, Lamshoft M, Ngamga D, Tane P, Spiteller M. 2010 Planta Med. 76, 640-643). Dihydrochalkon (floretyna) jest aktywnym inhibitorem tyrozynazy grzybowej (Zhang L-Q, Yang X-W, Zhang Y-B, Zhai Y-Y, Xu W, Zhao B, Liu D-L, Yu H-J, 2012 Food Chem 132, 936-942).Dihydrochalcones are synthesized by plants and are characterized by; sweet taste. Also, synthetic compounds having a dihydrochalcone group show a high sweetness impression (Winnig M, Bufe B, Kratochwil NA, Slack JP, Meyerhof W 2007 BMC Struct. Biol. 7, 66; Krammer G, Ley J, Riess T, Haug M, Paetz S, Kindel G, Schmidtmann R. Patent No .: US 20100233102; Sep, 16, 2010. Encyclopedia of Food Science, Food Technology and Nutrition. Academic Press, London 1993, Krutosikowa A., Uher M .: Natural and synthetic sweet-tasting substances PWN, Warsaw 1990; 2'-Hydroksydihydrocha Ikon is used as a building block in the synthesis of propafenone - the active substance of antiarrhythmic drugs (Noe CR, Knollmuller M, Oberhauser B, Steinbauer G, Wagner E. 1986 Chemische Berichte, 119, 729-743; Ecker G, Chiba P, Hitzler M, Schmid D, Visser K, Cordes HP, Csollei J, Seydel JK, Schaper KJ. 1996 J. Med. Chem. 39, 4767-4774; Ecker G, Noe CR, Fleischhacker W. 1997 Monatsh Chem. 128, 53-59) They are also known to be active against pathogenic microorganisms, including am-positive and gram-negative bacteria and fungi (Awouafack MD, Kusari S, Lamshoft M, Ngamga D, Tane P, Spiteller M. 2010 Planta Med. 76, 640-643). Dihydrochalcone (phloretin) is an active inhibitor of fungal tyrosinase (Zhang L-Q, Yang X-W, Zhang Y-B, Zhai Y-Y, Xu W, Zhao B, Liu D-L, Yu H-J, 2012 Food Chem 132, 936-942).

P r z y k ł a d. Do kolby Erlenmajera o pojemności 2000 cm3, w której znajduje się 500 cm3 sterylnej pożywki zawierającej 5 g aminobaku i 15 g glukozy, wprowadza się szczep Rhodotorula glutinis KCh 242. Po 72 godzinach jego wzrostu dodaje się 100 mg 1-(2'-hydroksyfenylo)-3-(4-metoksyfenylo)-prop-2-en-1-onu o wzorze 1, rozpuszczonego w 1 cm3 tetrahydrofuranu (THF). Transformację prowadzi się w 25 stopniach Celsjusza przy ciągłym wstrząsaniu przez 7 dni. Następnie mieszaninę poreakcyjną ekstrahuje się trzykrotnie chloroformem, osusza bezwodnym siarczanem magnezu i odparowuje rozpuszczalnik. Otrzymany ekstrakt oczyszcza się chromatograficznie, używając jako eluentu mieszaniny heksan i aceton 9:1.Example: The strain Rhodotorula glutinis KCh 242 is introduced into an Erlenmajer flask with a capacity of 2000 cm 3 containing 500 cm 3 of sterile medium containing 5 g of aminobac and 15 g of glucose. After 72 hours of its growth, 100 mg is added 1- (2'-hydroxyphenyl) -3- (4-methoxyphenyl) prop-2-en-1-one of formula 1, dissolved in 1 cm 3 of tetrahydrofuran (THF). The transformation is carried out at 25 degrees Celsius with continuous shaking for 7 days. The reaction mixture was then extracted three times with chloroform, dried with anhydrous magnesium sulfate, and the solvent was evaporated. The extract obtained is purified by chromatography using a 9: 1 mixture of hexane and acetone as the eluent.
