Abstract

Sposób wytwarzania (+)-(R)-7-hydroksyflawanonu, polega na tym, że do podłoża odpowiedniego dla grzybów strzępkowych wprowadza się szczep Aspergillus niger 13/5, następnie po upływie co najmniej 48 godzin do hodowli wprowadza się substrat, którym jest mieszanina racemiczna 7-hydroksyflawanonu o wzorze 1, rozpuszczona 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 is that an Aspergillus niger 13/5 strain is introduced into a medium suitable for filamentous fungi, then after at least 48 hours the substrate which is a mixture is introduced into the culture. racemic 7-hydroxyflavanone of formula 1, dissolved in a water-miscible organic solvent. The transformation is carried out with continuous shaking, at most 30 hours, after which the product is extracted with an organic solvent immiscible with water 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.
