Aglycon protopanaxatriol (APPT) has valuable pharmacological effects such as anti-inflammatory and anti-stress activities. However, the complete conversion of all typical glycosylated protopanaxatriol ginsenosides to APPT has not been achieved to date. β-Glycosidase from the hyperthermophilic

Complete biotransformation of protopanaxatriol-type ginsenosides in Panax ginseng leaf extract to aglycon protopanaxatriol by β-glycosidases from Dictyoglomus turgidum and Pyrococcus furiosus.
