The total arbutin content in the leaves of Bergenia crassifolia, B. ciliata and B. x ornata was determined. The highest arbutin content have been established for B. crassifolia and B. x ornata, and the lowest for B. ciliata.

All the tested aqueous extracts caused a dose-dependent increase in diphenolase activity of fungal tyrosinase in a similar way as arbutin. On the other hand, all the ethanol extracts inhibited the diphenolase activity of tyrosinase.
