The total tannin contents of three different QUERCUS ROBUR L. galls collected from Estonia, three reference galls, and two plants were estimated. The dry common oak gall-apples tannin content was 47.2%; in brown shiny galls - 4.2%, and in grape galls - 3.4%; in Chinese galls - 89.1%, in Turkey galls - 81.4%, and in pistacia galls - 52.4%; in oak bark - 9.1%, and in common tormentil roots - 21.1%. The present study shows that the QUERCUS ROBUR common oak gall-apples but not brown shiny galls or grape galls may be used as raw material for production of tannin containing traditional remedies.
Key words: Cynipid galls, Quercus robur, common oak, tannins.
