Abstract

Sposób wytwarzania (+)-(R)-7-hydroksyflawanonu o wzorze 2, polega na tym, że do podłoża odpowiedniego dla grzybów strzępkowych wprowadza się szczep Aspergillus niger KB, następnie po upływie co najmniej 48 godzin do hodowli wprowadza się substrat, którym jest (±)-octan 7-hydroksyflawanonu o wzorze 1, rozpuszczony w rozpuszczalniku organicznym mieszającym się z wodą, transformację prowadzi się przy ciągłym wstrząsaniu, co najwyżej 30 godzin, po czym produkt ekstrahuje się rozpuszczalnikiem organicznym niemieszającym się z wodą i oczyszcza chromatograficznie. Związek ten może znaleźć zastosowanie jako antyoksydant w przemyśle spożywczym oraz jako składnik preparatów farmaceutycznych i kosmetycznych.The method of producing (+) - (R) -7-hydroxyflavanone of the formula II consists in the introduction of Aspergillus niger KB strain into a medium suitable for filamentous fungi, then after at least 48 hours the substrate which is 7-hydroxyflavanone (±) -acetate 1, dissolved in a water-miscible organic solvent, transformation is carried out with continuous shaking, at most 30 hours, after which the product is extracted with a water-immiscible organic solvent and purified by chromatography. This compound can be used as an antioxidant in the food industry and as an ingredient in pharmaceutical and cosmetic preparations.
