Embodiment 1

[0037] A. Culture medium formula: slant medium formula: every liter of potato juice (peel the potato and cut it into small pieces, get 200g and put it into 1L 50% seawater, boil for 30min, filter, and use 50% seawater for the filtrate (seawater and tap water by volume) Add glucose 20g, agar 2.0g in ratio mixing) be settled to 1000ml). Seed culture medium formula: add 20g of glucose in every liter of potato juice (preparation method is the same as above). Fermentation medium formula: same as seed medium.

[0038] B. Fermentation process: slant culture: Prepare the culture medium according to the above slant culture medium formula, divide into test tubes, and prepare the slant after sterilizing at 121° C. for 30 minutes. The preserved endophytic fungus of mangrove plants, Aspergillus dwarfus CCTCC NO: M206063, was transferred to the slant medium and cultured at 25°C for 7 days. Shake flask culture: Prepare the medium according to the formula of the seed medium, pack into 500 E...

[0042] A. Medium formula: slant medium formula: per liter of potato juice (peel the potato and cut it into small pieces, take 300g and put it in 1L 100% seawater, boil for 30min, filter, and dilute the filtrate to 1000ml with 100% seawater) Add 30 g of glucose and 3.0 g of agar. Seed medium formula: add 30g of sucrose in every liter of potato juice (preparation method is the same as above). Fermentation medium formula: same as seed medium.

[0043] B. Fermentation process: slant culture: Prepare the culture medium according to the above slant culture medium formula, divide into test tubes, and prepare the slant after sterilizing at 121° C. for 30 minutes. The preserved endophytic fungus of mangrove plants, Aspergillus dwarfus CCTCC NO: M206063, was transferred to the slant medium and cultured at 28°C for 5 days. Shake flask culture: Prepare the medium according to the above seed medium formula, pack it into Erlenmeyer flasks (100ml / bottle), sterilize (121°C, 30min), insert t...

Abstract

The gram Liewei mellow preparation method and in the system anti-acetylcholin esterase medicine's application, relates to one kind of gram Liewei to be mellow, and provides one kind to originate from the mangrove forest endogenous fungus secondary metabolite gram Liewei mellow preparation method and the application. The preparation method is: dwarf rods Aspergillus BYY-1 seed culture; submerged fermentation; broth filter strains; concentrated filtrate decompression after repeatedly using organic solvent extraction, collection and decompression organic phase was concentrated extracts; Extracts of the silica gel column chromatography and recrystallization obtained after refining grams Levy alcohol. Levy alcohol grams of acetylcholinesterase inhibition with notable is a reversible inhibitor of acetylcholinesterase, can be used for the treatment of Alzheimer's and other associated with a lack of acetylcholine diseases drugs.

Description

technical field [0001] The present invention relates to a kind of clavatol (clavatol), relate in particular to a kind of preparation method that comes from mangrove endophytic fungi-Aspergillus dwarf clavatanicus BYY-1 (A.clavatonanicus) fungal metabolite clavatol compound, and The new application of the compound in the preparation of medicines for treating Alzheimer's disease and other diseases related to acetylcholine deficiency. Background technique [0002] Alzheimer's disease is a neurodegenerative disease, the incidence rate is about 10% in the elderly population aged 65-69, and the prevalence rate in the population over 85 is about 47%, and it is still increasing. Alzheimer's disease seriously endangers the health and quality of life of the elderly. After the disease, the patient will gradually lose the ability of learning and memory, resulting in serious obstacles to self-care and death. [0003] Alzheimer's disease or Alzheimer's Disease (Alzheimer's Disease, AD) i...
