English title: Carbohydrates in the sap of silver birch and its curly grained formAbstract
Carbohydrates of the sap of six curly and four silver birches (Betula pendula f. carelica Sok. and B. pendula Roth) were analysed by gas chromatography as trimethylsilyl derivates both from hydrolysed and unhydrolyzed samples. Sorbitol was identified from silver birch sap only. In each of the two groups there were glucose and fructose. No other carbohydrates were discovered. The hydrolysis had no influence on the results.
