Abstract

Influence of a birch outer-bark grinding and short-time treatment by overheated steam on the yield and composition of triterpenes products, obtained by bark acetylation with acetic acid was studied. At selected conditions of birch outer-bark activation and acetylation the products, containing mainly betulin or betulin diacetate were produced.
