Extractive Bioconversion

The objective of this study was the investigation of the extractive bioconversion of apigenin-7-O-?-glucoside in camomile ligulate flowers into apigenin by autofermentation in polyethylene glycol 6000/dextran 200000 two-phase system. In 22.5% polyethylene glycol/14% dextran aqueous two-phase system the obtained yield of apigenin in the top phase was 96.5%. In the presence of plant material that partiotioned to the interphase, the yield of apigenin in the top phase was 3.5 times higher in comparison to the model system.

The study is concerned with the conversion of apigenin-7-O-?-glucoside into apigenin in polyethylene glycol 6000 / dextran 20000 aqueous two-phase system by ?-glucosidase. Apigenin was separated from apigenin-7-O-?-glucoside and ?-glucosidase by their partition into opposite phases. In 14% PEG / 22.5% DEX aqueous two-phase system obtained yield of apigenin in top phase was 108%.
