FIELD: food industry.
SUBSTANCE: method for processing silver fir wood green envisages raw material milling, the raw material treatment with an alkali solution, the raw material filtering to remove the resultant solution, acids separation by way of extraction with an organic solvent. After milling the raw material is treated with 0.1-0.5% water solution of a mineral acid at a temperature of 50±5°C with the filtered raw material subsequent two-times washing with water. Then the blended acid filtrates are concentrated by way of water boiling out in a rotor evaporator at a temperature of 60°C. Polysaccharides are sedimented from the resultant concentrate with excessive ethanol. The raw material remaining after polysaccharides extraction is subjected to treatment with an alkali and an organic solvent to separate triterpenic acids.
EFFECT: invention enables silver fir wood green processing to produce polysaccharides and triterpenic acids and to increase the target products yield.
