Abstract

The invention relates to a pretreatment steam extraction method for rosin, arabinogalactan and dihydroquercetin in larch wood powder. The method comprises the following steps of S1, water immersion pretreatment, wherein the larch wood powder is subjected to water immersion treatment, filtration is conducted to obtain a filtrate containing arabinogalactan, and the moist larch wood powder is reserved; S2, steam extraction, wherein steam with the pressure of 0.2 MPa is added to the moist larch wood powder treated in the first step for steam extraction, and filtration is conducted to obtain an extraction solution; S3, concentration and drying of the extraction solution, wherein the extraction solution of the third step is concentrated and dried to obtain an extract containing rosin and dihydroquercetin; S4, recrystallization, wherein the extract containing the rosin and dihydroquercetin is recrystallized to obtain the refined rosin and dihydroquercetin separately. The method has the advantages that the material is directly used without being dried, the method is economical and environmentally friendly, many products are generated, the yield is high, solvents are not needed in all the processes, and the method is low in cost and suitable for industrial large-scale production.

Description

Technical field

[0001] The invention relates to a pretreatment steam method for extracting pine resin, arabinogalactan and dihydroquercetin from larch wood powder, and belongs to the technical field of flavonoid extraction. Background technique

[0002] Turpentine is an important raw material for chemical industry, mainly used to make raw materials for paint. Arabinogalactan can reduce the particle size of oil-in-water emulsion particles and increase the proportion of small-size emulsion particles. It has excellent emulsification and dispersion capabilities and can be used as skin conditioners, moisturizers, thickeners, and glues. Coagulant, film-forming agent, etc., added to cosmetics as a film forming agent, which can slow down the loss of water.

[0003] Dihydroquercetin has a strong antioxidant capacity, can effectively eliminate excess free radicals from the human body, promote capillary permeability, its antioxidant properties are better than many existing antioxidants, and ...
