Biotransformation of Liquiritin in Glycyrrhiza uralensis Fisch Extract into Liquiritigenin by Plant Crude Enzymes

Liquiritin in licorice (Glycyrrhiza uralensis Fisch) extract was treated with three different plant crude enzymes (Prunus dulcis enzyme; PDE, P. armeniaca enzyme; PAE and P. persica enzyme; PPE) for biotransformation. The resulting product of liquiritin was analyzed by TLC and HPLC. The β-glucosidas...

Summary:Liquiritin in licorice (Glycyrrhiza uralensis Fisch) extract was treated with three different plant crude enzymes (Prunus dulcis enzyme; PDE, P. armeniaca enzyme; PAE and P. persica enzyme; PPE) for biotransformation. The resulting product of liquiritin was analyzed by TLC and HPLC. The β-glucosidase activities of crude enzymes were 259.6 U/g (PDE), 407.6 U/g (PAE) and 445.8 U/g (PPE), respectively. The liquiritin was converted to liquiritigenin after 12 hours of incubation with the crude enzymes. Liquiritigenin content reached its maximum level after the treatment with PPE at 37℃.
