Abstract: A method for extraction and multi-scenario utilization of flaxseed protein-polysaccharide natural mixture is disclosed, comprising:(1) raw material pretreatment; (2) extraction of mixture I; (3) multi-scenario utilization of mixture I; (4) extraction of mixture II; and (5) multi-scenario utilization of mixture II. Compared with the traditional extraction mode (such as alkali-solution and acid-isolation method) of flaxseed protein, the method of the invention can enrich the flaxseed protein more efficiently, greenly and moderately, and can co-extract polysaccharide from flaxseed meal to form the flaxseed protein-polysaccharide natural mixture. Physical field/bio-enzyme coupling ultrasonic technique solves the bottleneck problem of low extraction rate of the flaxseed protein-polysaccharide natural mixture by water extraction method.

Abstract: The present disclosure provides an arctigenin liquid nano-preparation and a preparation method thereof, and relates to the technical field of pharmaceutical preparation. In the present disclosure, arctigenin is prepared into a liquid nano-preparation, having advantages of distribution of a droplet diameter on nanoscale, significantly increased specific surface area, rapid absorption, and high bioavailability. Meanwhile, nano-preparation entered the body can be captured by wandering leucocytes, and a medicament is delivered to inflammatory lesions through chemiotaxis, thereby conferring a targeted drug delivery feature on the arctigenin and making a therapy more targeted. Moreover, in the present disclosure, the arctigenin is dissolved in an oil phase, and the oil phase is dissolved in water by emulsification to further make the arctigenin dissolve in the water and increase water solubility of the arctigenin.
