METHOD OF PRODUCING SPRUCE CONE EXTRACT WITH ANTIOXIDANT ACTIVITY AND WATER SOLUBILITY Russian patent published in 2024 - IPC A61K36/15 B01D11/02 A61P39/06 

FIELD: pharmaceutical industry.

SUBSTANCE: invention relates to a method of producing an extract with antioxidant activity and solubility in water. A method of producing an extract with antioxidant activity and solubility in water, in which spruce cones, crushed to a particle size that passes through a sieve with a hole diameter of 2 mm, are extracted with water in a ratio of 1:30 for 1.5 hours at a temperature of 80–85°C, then the extract is separated from the raw material by filtration and concentrated under vacuum at a temperature of 80–85°C 10 times of the original volume, the resulting extract is freed from the inactive fraction by sharply cooling the extract at a temperature of -18°C for 15 minutes, the precipitate is discarded, the supernatant is freeze-dried.

EFFECT: above method provides a dry extract of Norway spruce cones, which has pronounced antioxidant activity and good solubility in water at room temperature 20°C.
