Production of acteoside from Cistanche tubulosa by β-glucosidase.

Acteoside and echinacoside are the major active components of Herba Cistanches. Facilitated β-glucosidation was investigated as a means of increasing harvest of acteoside from Cistanche tubulosa. Fresh Cistanche tubulosa was treated by microwave moisture processing to inactivate enzymes. β-Glucosidase is capable of hydrolyzing echinacoside for the production of acteoside, so six β-glucosidases were compared for their efficiency, specific...
