The invention discloses a series of 8-substitued oxoisoaporphine derivatives as well as a synthetic method and application thereof. The synthetic method comprises the following steps: (1) performing cyclization reaction on 3-chlorophthalic anhydride and phenylethylamine as raw materials twice to construct an 8-Cl-1-azabenzanthrone matrix; (2) ammonifying the 8-Cl-1-azabenzanthrone matrix to obtain 8-amino-7H-dibenzoquinoline-7-ketone; (3) reacting 8-amino-7H-dibenzoquinoline-7-ketone with an acyl chloride compound connected with piperidine to obtain corresponding target products. A study of the applicant discovers that the derivatives have very good inhibition activity on acetylcholin esterase, have relatively good potential medicinal values and are expectedly used for treating Alzheimer diseases, cerebral vascular dementia and related diseases caused by reduction of similar cholinergic neurotransmitters. The structure of the 8-substitued oxoisoaporphine derivatives is shown in a formula.

The invention discloses cell membrane-simulated surface-modified bacterial cellulose and a preparation method and application thereof. The method comprises the following steps: oxidizing bacterial cellulose with a periodate to obtain aldehyde-based bacterial cellulose; and reacting the aldehyde-based bacterial cellulose with a disubstituted choline phosphonate, adding a reaction product into an alkaline solution for hydrolysis, and performing washing with water and drying to obtain the cell membrane-simulated surface-modified bacterial cellulose. The phosphorylcholine-based bacterial celluloseprepared by the invention is non-toxic to cells under physiological environment, and has good anti-protein adhesion and anti-cell adhesion. The preparation method has mild conditions, is easy to operate, can obtain a cell membrane-simulated modified bacterial cellulose material with anti-bio adhesion on the surface, and is suitable for preparing anti-bio adhesion and adhesion-proof biomaterials.

The invention discloses a tilapia mossambica larva starter feed and a preparation method thereof. The tilapia mossambica larva starter feed comprises the following components in parts by weight: 50-65parts of mussel powder, 20-40 parts of dried porcine soluble, 1-6 parts of hippophae rhamnoides fruit powder, 1-5 parts of vital gluten, 1-5 parts of sodium copper chlorophyllin, 0.1-0.5 part of choline, 0.5-2 part of calcium dihydrogen phosphate, 0.5-2 part of vitamin premix, 0.5-2 part of mineral premix and 2-6 parts of grease. According to the invention, the tilapia mossambica larva starter feed is rich in nutrition, good in food calling performance, easy to eat by the tilapia mossambica larva, good in palatability and easy to digest by the tilapia mossambica larva; and the survival rate of the tilapia mossambica larva and the development and growth level can be improved by eating the tilapia mossambica larva starter feed.

The invention provides a method for producing natural forage-use yolk toner through bean dregs and endives. The method includes the steps of airing or drying endives, bean dregs, orange peel, allium Chinese root and stem residues and plump kephyrion, smashing the raw materials respectively into coarse powder, weighing, by weight, 22-24 parts of endive powder, 13-15 parts of bean dregs, 10-12 parts of orange peel powder, 3-5 parts of allium Chinese root and stem residues, 5.6 parts of plump kephyrion powder and 7 parts of auxiliaries, evenly mixing the coarse powder of all the raw materials with the auxiliaries, processing the raw materials through a high-energy vibration mill twice so that all the raw materials can be subjected to two times of different solid mechano-chemistry reactions, and conducting screening through a 400-mesh sieve to obtain the finished product. By means of the method, endive choline components are greatly reduced, the animal absorption rate of active ingredients in pericarp is increased, the problems that endives and pericarp are poor in palatability and prone to corrosion are solved, the yolk color value of poultry can be increased by 90% or above through the produced natural forage-use yolk toner, the production cost is reduced, and the problem that the environment is polluted by factory waste is solved.
