Enzymatic upcycling of wild-simulated ginseng leaves for enhancing biological activities and compound K.

ABSTRACT: Compound K (CK), a ginsenoside with high bioavailability, is present at low levels in wild-simulated ginseng leaves (WSGL). WSGL contains the CK precursors, Rd and F2, in amounts up to 26.4 ± 0.4 and 24.1 ± 1.9 mg/g extract, respectively. In this study, CK production in WGSL reached 25.9 ± 1.0 mg/g extract following treatment with Viscozyme, Celluclast 1.5 L, Pectinex Ultra SP-L, and their combination. The antioxidant activities indicated by oxygen radical absorbance capacity, ferric reducing antioxidant power, and ABTS- and DPPH radical scavenging activity of enzyme-treated WSGL were enhanced 1.69-, 2.51-, 2.88-, and 1.80-fold, respectively, compared to non-treated WSGL. Furthermore, the CK-enriched WSGL demonstrated a 1.94-fold decrease in SA-β-galactosidase expression in human dermal fi
