The invention discloses a method for preparing rare saponin by utilizing panax japonicus endogenous enzyme, and relates to the technical field of extraction, the panax japonicus plant material or crude extract thereof is directly taken as a starting point, the enzyme system is simple and convenient to obtain (fresh medicinal material low-temperature homogenate extraction or direct use of freeze-dried powder), the reaction system is simple, and the operation is easy. According to the preparation process provided by the invention, the catalytic action of endogenous enzyme is fully utilized, so that the introduction of exogenous substances (acid-base, protein and the like) in the extract is completely avoided; the method disclosed by the invention is high in catalytic efficiency, can quickly realize complete conversion of saponin (within 10min) under specific conditions, and has extremely high industrial application.

The invention provides application of a pharmaceutical composition in preparation of anti-influenza virus drugs, and belongs to the technical field of biological medicines. The invention provides a pharmaceutical composition of carabrone, panax japonicus saponin IVa and plantamajoside. Multi-target intervention is realized aiming at key stages (such as adsorption, replication and release) of an influenza virus life cycle. Experiments show that the composition can significantly inhibit replication and proliferation of influenza viruses. The natural component composition disclosed by the invention has the advantage of higher safety, provides a safer, effective and economic treatment choice for clinic, and has remarkable conversion value and market potential.

The invention belongs to the technical field of food processing, and particularly relates to a panax japonicus and dendrobium protocorm co-extract as well as a preparation method and application thereof. The preparation method of the co-extract comprises the following steps: (1) extraction: mixing panax japonicus and dendrobium protocorm, adding a natural deep eutectic solvent, controlling the solid-to-liquid ratio to be 1: (30-50) g / mL, and extracting under an ultrasonic condition to obtain a crude extract; (2) anti-solvent precipitation and purification: dropwise adding the crude extract obtained in the step (1) into excessive ethanol, standing for precipitation, and carrying out centrifugal separation to obtain a precipitate; and (3) drying treatment: drying the precipitate obtained in the step (2) at 40 DEG C until the weight is constant, so as to obtain the panax japonicus and dendrobium protocorm co-extract. The co-extract can remarkably promote proliferation and acid production of various probiotics, effectively regulate intestinal flora balance, show excellent prebiotic activity and have the potential of being developed into functional medicines or health-care foods.

This utility model discloses a storage and preservation device for bamboo-joint ginseng, including a sealed box. A light-shielding layer is fixedly installed on the inner wall of the sealed box, and the box is divided into multiple inner cavities by at least one dividing layer. A drawer unit is slidably installed in each inner cavity, and the bottom of the drawer unit is provided with a wavy, hollowed-out elastic silicone mesh tray. The light-shielding layer is connected to the lower part of the dividing layer via a disassembly and assembly mechanism. This utility model offers upgraded physical protection: the hollowed-out structure of the wavy, elastic silicone mesh tray disperses the stress on the bamboo-joint ginseng nodes, resulting in a reduced fracture rate when the ginseng is subjected to a 500g load. The light-shielding layer is efficiently disassembled and assembled: the Y-shaped insertion groove and the inclined guide design of the limiting block shorten the replacement time of the light-shielding layer, and the elastic component automatically locks to prevent loosening.

This invention discloses the application of *Gynostemma pentaphyllum* polysaccharide in the preparation of drugs against porcine reproductive and respiratory syndrome virus (PRRSV). This invention explores the regulatory effect of *Gynostemma pentaphyllum* polysaccharide on PRRSV replication, and for the first time discovers that *Gynostemma pentaphyllum* polysaccharide can effectively inhibit PRRSV replication in Marc-145 cells. Based on this, this invention proposes a new application of *Gynostemma pentaphyllum* polysaccharide in the preparation of drugs against PRRSV, preferably with a concentration of 12.5 μg / mL to 100 μg / mL. This invention enriches the research on the antiviral activity of *Gynostemma pentaphyllum* polysaccharide and also provides a new technical means for the research and clinical application of anti-PRRSV drugs.
