FIELD: biotechnology.
SUBSTANCE: method of processing wood green of fir to obtain fir oil, chlorophyll-carotene paste, aqueous extract of fir, comprising the sequential extraction of wood green with aqueous isopropanol, extraction with water, concentration of the isopropanol extract, hydro-distillation of the volatile components from the concentrate of the isopropanol extract to obtain fir oil, washing with water of hot bottom products for extraction of hydrophilic components and their separation from the lipophilic part, combining of hydrophilic components with an aqueous extract of wood green and concentration in vacuum to obtain the total aqueous fir extract, saponification of lipophilic part with aqueous solution of sodium hydroxide to obtain chlorophyll-carotene paste, under certain conditions.
EFFECT: method enables to extract efficiently fir oil, chlorophyll-carotene paste, aqueous fir extract of wood green of fir.
