The application discloses a method for reducing toxicity and increasing efficiency of ginkgo biloba juice fermented by macroreticular resin assisted probiotics, and the strains are ginkgo endogenous lactobacillus, and the names are lactobacillus plantarum TY-HYB-SYY-Y2 and lactobacillus pentosus TY-HYB-SYY-Y3 , and the preservation numbers of the China General Microbiological Culture Collection Center are CGMCC No. 25128 and CGMCC No. 25127 respectively; the macroreticular resin is a macroreticular adsorption resin. The application finds that the ginkgo endogenous lactobacillus can promote the reduction of the content of toxic substances such as ginkgoic acid and ginkgo poison during the fermentation of ginkgo biloba juice, and at the same time, the content of ginkgo lactone is increased, and it is found that the content of ginkgo acid is further reduced during the macroreticular resin assisted fermentation process, and a more obvious reduction effect is achieved.

The invention relates to the technical field of nutrition injections, in particular to a nutrition injection for fruit tree trunks and a preparation method of the nutrition injection. The nutrition injection is prepared from the following raw materials: urea, a compound nutrient, an additive solution, cane sugar and water. In the preparation process of the nutrition injection for the fruit tree trunks, the ginkgo leaves, the rosemary and the lotus leaves are combined and added, and bilobalide components of the ginkgo leaves can promote division and elongation of root cells of fruit trees, so that the root systems of the fruit trees are more developed, and the water and nutrient absorption capacity of the fruit trees after transplanting is enhanced; rosmarinic acid has the effect of adjusting plant hormone balance and can stimulate fruit trees to root again at damaged positions of root systems after transplanting and improve the activity and absorption efficiency of the root systems, nuciferine is beneficial to improving the growth environment of the fruit tree root systems and promoting microbial activity of the fruit tree root systems, good conditions are provided for growth of the fruit tree root systems, and the yield of the fruit trees is increased. The yield and the transplanting survival rate of the fruit trees are effectively improved.

The invention relates to the technical field of functional food preparation, and discloses a ginkgo biloba extract based on functional food and a preparation process of the ginkgo biloba extract. The preparation process comprises the following steps: (1) treating ginkgo leaves; (2) carrying out solid-liquid separation, cooling the filtrate A, and crushing filter residues; (3) immersing the filter residue in water, carrying out solid-liquid separation to obtain a filtrate B, carrying out macroporous resin adsorption treatment on the filtrate B, and mixing the filtrate B with the filtrate A to obtain a ginkgo leaf extracting solution; (4) adding the filter residue, starch hydrolysate and glycosidase, and performing microwave extraction; (5) introducing supercritical CO2 for extraction; (6) removing CO2 from the extract, and concentrating to obtain the ginkgo leaf extract; and (7) obtaining the functional food. According to the method, the extraction rate of ginkgo flavone and ginkgolide is increased, no solvent such as ethyl alcohol participates in the whole preparation process, and the problem that the quality of the extract is reduced due to the fact that an alcohol solvent is prone to acid-base reaction is solved.
