Abstract
Modified technology of obtaining arabinogalactan from wood of
Larix sibirica and
Larix gmelinii on the basis of aqueous extraction of arabinogalactan in the ultrasonic set-up, filtration of the extract, its separation into fractions by means of ultrasonic spraying and concentrating in a rotary vacuum evaporator is considered. The concentrate is precipitated in the organic solvent, washed, dried and ground. It is notable that arabinogalactan extraction is carried out without preliminary extraction of dihydroquercetin.
