FIELD: food industry.
SUBSTANCE: method envisages milling coniferous trees greens. Then one extracts the tree greens with ethyl acetate and chloroform. Then remains are extracted in three stages: with distilled water, with water acidified with hydrochloric acid, with water solution of potassium hydroxide. Then one proceeds with concentration and settlement with ethyl alcohol. Then the sediment is centrifuged, dissolved in water and dialysed against distilled water. One performs lyophilic drying of the target product.
EFFECT: invention allows to produce pectin polysaccharides and glucuron- oxylan class hemicellulases of coniferous trees greens with high yield and high purification degree.
